China ’ s News Media Tweeting , Competing With US Sources

This paper examines China’s recent initiative on international social media and assesses its effectiveness in counteracting Western dominance in international communication. Analysing data collected from the Twitter platform of three public accounts run by China’s state news media CGTN, People’s Daily and Xinhua News, it finds that their news agenda about China focuses on the country’s top leaders and achievements, while that about other countries is on breaking news. Their China-related tweets receive more positive replies than their non-China-related tweets, but tweets about China’s top leader, Xi Jinping, receive fewer positive replies than soft news items. Analysis of Twitter data of the #southchinasea hashtag finds that China’s media mainly compete with US sources for influence. China’s state media influence the news agenda on the issue by active and persistent tweeting and drawing retweets. However, US sources are more influential as a whole in setting the news agenda and amplifying certain news events. The study finds evidence that forces seemingly unfriendly to both China and the US attempt to skew the news agenda of #southchinasea using manipulated accounts.


Introduction
Western dominance of international communication (MacBride et al., 1980) manifested as a real diplomatic issue for China in the 1990s, after Western television news beamed images of the injured and dead next to rolling military tanks in the streets of Beijing in early June 1989 to the living rooms of audiences around the world.To counteract the negative image created by such reports -which China described as ' demonisation' (Li, 1998), and which resulted in punitive diplomatic measures by other countries -China strengthened its external communication in the decade afterwards.Resorting to the latest communication technologies, China launched its first externally targeted satellite television channel in 1992 before building a global satellite television network in the 2000s.It built foreign-language news websites from 1997 and accomplished the China National Network in 2001 (Zhang, 2009).As social media become an increasingly important source of news, China's news media have lately embraced international social media platforms for external communication -although, ironically, many some of their news from social media (Shearer & Gottfried, 2017).Since 2013, at least half of Twitter users in the US have used the platform as a news source.In late 2017 the figure was 74 per cent, up 15 per cent from early 2016, probably because of the Twitter activities of the US President Donald Trump (Newman et al., 2017).Internationally, Twitter is used as a news source by a higher percentage of its users than other social media, although Facebook and some apps designed for private communication are more popular news sources (Newman et al., 2017).The private communication on Facebook and privately -oriented apps, however, are not accessible to researchers for privacy reasons.This study, therefore, concentrates on the public communication on Twitter.
News media are the most retweeted (Meraz & Papacharissi, 2013) and most influential users on Twitter (Lee et al., 2010), but the influence of China's news media on Twitter is rarely studied.There is one notable exception: Guo, Mays & Wang (2017) found that in 2011-14 most tweets about the South China Sea focused on China in a negative way, and that US newspapers were more influential than China's newspapers in forecasting discussion of bilateral relationships between nations involved in the South China Sea dispute on Twitter.

China's news media on Twitter
Twitter, along with several other international social media platforms, has not been legitimately accessible to users in China since 2009.However, a study conducted in 2015 estimated that users who reside in mainland China, and those who reside outside but who are significantly connected in following or interacting with users inside mainland China, together hold 8,275 Twitter accounts (Song, Faris, & Kelly, 2015).
The official blocking has not stopped news organisations in China running accounts on international social media.Our search found the following verified Twitter accounts belonging to Chinese media, some of which are also associated with other seemingly legitimate un-verified accounts: • China Radio International (CRI) (now called @ChinaPlusNews) since April 2009 • Global Times (@globaltimesnews) since June 2009 • China.org.cn(@chinaorgcn) since May 2010 • China Daily (@ChinaDailyAsia) since April 2011 • People's Daily (@PDChina) since May 2011 • Xinhua News (@XHNews) since February 2012 • Guangming Daily (@Guangming_Daily) since June 2012 • China Central Television News (@CCTVnews) 1 since January 2013 (superseded by China Global Television Network, @CGTNOfficial, from 4 January 2017) • Sixth Tone (@SixthTone) since February 2016 Un-verified accounts of official organisations in China include: • China Pictorial (@CHINA_PICTORIAL) since March 2014 • Beijing Review (@BeijingReview) since June 2009 • China State Council Information Office (@chinascio) since September 2015 We found no verified accounts run by commercial news media, such as Caijing or Caixin.Nor did we find a verified or credible account representing the Chinese president, Xi Jinping, on Twitter.It appears that state media are used as China's official voice to address and interact with the international audience.This paper seeks to examine this voice by analysing the news agenda of selected verified official accounts of China's state media.It aims to assess the influence of these accounts by observing the responses to their tweets.A case study of the #southchinasea hashtag is used to further examine China's relative influence on Twitter.Specifically, the study asks: 1. What are the most prominent themes in the tweets of China's state media?2. What is the sentiment of the replies received by the tweets?3. What are the most prominent themes in the original tweets containing #southchinasea related to China? 4. What are the most prominent themes in the entirety of tweets including retweets and replies containing #southchinasea related to China?
Comparing the results of questions 3 and 4 is expected to help us assess the impact of China's state media in the #southchinasea sphere.

Data and Methods
Influence on Twitter is usually evaluated by the structural position of the user in the social network (common measures are page-rank and number of followers), or the extent of information adoption by others of the user's messages (common measures being the number of retweets, comments, and mentions) (Lee et al., 2010), but these two types of measures do not necessarily correlate (Cha, Haddadi, Benevenuto and Gummadi, 2010;Lee et al., 2010).This study relies on the number of followers of the account, the Like and retweet counts of the tweets from Twitter's user metrics, and the number of replies to the tweets that we collected as indicators of influence.
The design and interpretation of the study are sensitised by the knowledge that user metrics of social media are subject to manipulation.Cases of fake follower numbers on Twitter, including of Xinhua News, have been reported (Confessore, Dance, Harris, & Hansen, 2018;Grundy, 2015).Social bots have been found to manufacture tweets and tamper with human interaction on Twitter to amplify visibility of certain information or misinformation (Shao, Ciampaglia, Varol, Flammini, & Menczer, 2017).Seemingly manipulated accounts have been observed to conduct propaganda on Twitter by China and against China (Bolsover, 2017).In China, the requirement for real name registration of social media accounts means that similar manipulation of information often takes the form of hidden paid posters, known as the 'Internet water army' (shui jun, 水军) in the commercial context (Chen, Wu, Srinivasan, & Zhang, 2013), and the 'fifty-cent army' (wu mao dang, 五毛党) in the service of the government (Han, 2015;King, Pan, & Roberts, 2017).
Two Twitter datasets were collected -one of China's state media accounts and one of the #southchinasea hashtag.The first dataset contains data from the following three public accounts on Twitter: • CCTVNEWS/China Global Television Network: @cctvnews/@CGTNOfficial • People's Daily, China: @PDChina • China Xinhua News: @XHNews.
These three media are among the most important central-level media supported by the Chinese state to expand globally.Their Twitter accounts gather far larger followings than any other account listed above.On 13 April 2018, the Twitter user interface showed that @CGTNOfficial had 7.64 million followers, @PDChina 4.66 million, and @XHNews 12 million.The largest following of the other accounts of China's news media was for China Radio International (CRI) (@ChinaPlusNews), with 597,000 followers, and China.org.cn(@chinaorgcn), with 531,000 followers.The three selected accounts are also associated with a number of regionally focused verified (e.g.@cgtnamerica, @XHJapanese) and unverified (e.g.@xinhua_hindi) accounts, and accounts that focus on individual programmes (e.g.@CGTNDCproducers) with smaller followings and which were not included in this analysis.Hence the three media outlets, which also hold accounts on Facebook, YouTube and Instagram, are considered the most effective of China's media on Twitter.
The South China Sea dispute was considered an appropriate case study because China's expansive and competing territorial claims against neighbouring countries in Asia, which also threaten the navigational routes of several other countries, necessitates competition for supportive international public opinion.
The #southchinasea hashtag was selected as the field site of the dispute as it was far more popular than another hashtag focused on the issue, #south_china_sea, which was the only other similar hashtag identified through frequency analysis of hashtags of our #southchinasea dataset.Using TrISMA, a tool developed in Australia to track, store and process the entirety of public social media data posted by Australians (Bruns et al., 2016), we found that the number of Australian tweets containing the #south_china_sea hashtag was a tiny fraction of those containing #southchinasea.We assume a similar distribution would apply to the global dataset.The hashtag search was preferred to keyword-combination searches as it collects tweets tagged by their authors as focused on the South China Sea, making them more relevant for our purpose.
We started by using the DMI-TCAT (Digital Methods Initiative Twitter Capture and Analysis Toolset), an open-source tool developed by the University of Amsterdam 1 (which sources data from the Twitter streaming API in real time) to collect data.We supplemented the tweets and replies collected by capturing Like and retweet data directly from Twitter's REST API for China's media dataset on 25 October 2017, and for the #southchinasea dataset on 27 November 2017.
The period studied of China's state media dataset was 1 October 2016 to 24 October 2017.The coverage of an entire year should give a clear overview of the activities of state media.
The period studied in the #southchinasea dataset was 13 December 2016 to 23 May 2017.The selection took into consideration the development of events in the South China Sea as reflected in Google Trends since 1 January 2009.Interest in 'south china sea' peaked on 12 July 2016, when a tribunal of the Permanent Court of Arbitration (PCA) in the Hague ruled against China's claim to historical territorial rights within the 'nine-dash line' (its self-declared territorial boundary) in the South China Sea.After that public interest in the issue declined until around 15 December 2016, when China seized a US drone.This also brought to light that China was installing weapons in the area, and had just started daily passenger flights to one of the disputed islands.Interest continued to decline until a very small peak around 19 May 2017, when China threatened to go to war with the Philippines over the dispute and a draft framework was then finalised among ASEAN countries about conduct in the South China Sea.We are satisfied that the selected period involves concerns at international and regional levels affecting multiple countries.
Twitter's streaming API enforces restrictions on data scraping to a maximum of 1 per cent of the entire Twitter data stream at the moment of collection.This could potentially affect the #southchinasea dataset.We evaluated the comprehensiveness of the collected #southchinasea dataset by comparing the Australian messages collected in the dataset to those collected by TrISMA, and found that 97 per cent of the Australian #southchinasea messages in TrISMA were included in our #southchinasea dataset.This gives us confidence that our #southchinasea dataset captures the overwhelming majority of relevant messages.Restrictions applied by the Twitter REST API are not expected to affect our collection of the China media dataset.
Among the data collected using the above methods, English-language messages were counted and further analysed.While all the tweets collected from the China state media accounts were in English, 34 per cent of replies made to their tweets that contained non-English (ASCII) symbols (including 6 per cent of English-language tweets containing the truncation symbol "…") were discarded.Ten per cent of collected messages in the #southchinasea dataset containing non-English symbols were discarded.

Theme analysis
To study the news agenda of China's state media on Twitter, themes of their tweets (excluding retweets but including replies made by the state media) were analysed by word frequency and word co-occurrence frequency using the scikit-learn package in the Python 3.6 script (http://scikit-learn.org/stable/index.html).In addition to the standard Stopword list precompiled by the package, words standing for Monday to Sunday and URLs were further excluded before running the analyses.We take frequency as the number of tweets in which a word appears, meaning that even if a word appears in the same tweet twice or more, frequency is still counted as one.A 'word' is defined as a single word in the first round of analysis, and a two-word term (two consecutive words) in the second round.In each round of analysis, co-occurrence frequency analysis was conducted among the most frequent 50 words.
In the #southchinasea dataset, word frequency and co-occurrence frequency analyses as described above were applied to the original tweets (excluding retweets and replies), and then to the entirety of messages (including original tweets, retweets and replies received by the original tweets).The words #southchinasea and 'southchinasea' were additionally excluded in the analyses.

Sentiment analysis
Since Twitter is mainly a news medium (Kwak, et al., 2010), we reckoned that applying sentiment analysis on information-giving tweets would not be productive.Instead, sentiment analysis was conducted on the replies received to the tweets from the selected accounts in the China state media dataset, using version 3.2.5 of the Natural Language Toolkit package (http://www.nltk.org/),separately on tweets whose content was directly related to China and tweets that did not directly relate to China.To split the dataset into China and non-China-related, we followed a three-step process.First, all the tweets published by the three accounts were filtered using a list we compiled of 227 Chinarelated keywords, which included geographical, political and cultural keywords, helped by searches on various China-related websites.In step two, we compiled a similar keyword list that related to foreign countries and landmarks to identify a non-China-related body of tweets.We were then left with 5,191 tweets that did not contain any China or foreign-related keywords in the compiled lists.These tweets were manually coded into China and non-China-related by the two authors, after a trial coding of 2 per cent of the same tweets, which produced 91.3 per cent inter-coder agreement (Krippendorff's Alpha 0.85).
Reliability of the automated sentiment analysis on the replies was tested through comparing the automated coding to manual coding of a random sample of 0.5 per cent each of the replies from the China-and non-China-related bodies of tweets.While automated coding generated sentiment scores on a continuous scale from -1 to +1, the first author manually coded according to a 5-point scale (-1, -0.5, 0, +0.5, +1) while the second author attempted a 9-point scale (-1, -0.75, -0.5, -0.25, 0, through to +1).We were able to obtain satisfactory agreement between automated and manual coding when we converted the scores to a 3-point scale (-1, 0, +1) based on the following rules: • Same polarity, and the absolute value (irrespective of whether the numeral is positive or negative in value) of both coding is greater than 0.1 • Different polarities, or one/both are zero, and absolute value of both coding is less than 0.1 9 69.3 per cent (Krippendorff's Alpha 0.53) between automated and the first author's coding of the China sample 9 68.0 per cent (Krippendorff's Alpha 0.52) between automated and the second author's coding of the China sample 9 70.9 per cent (Krippendorff's Alpha 0.52) between automated and the first author's coding of the non-China sample 9 70.0 per cent (Krippendorff's Alpha 0.56) between the two authors' coding of the China sample Since the agreement between automated coding and each of the author's is comparable to the agreement between the manual coding done by the two authors, we were satisfied that the automated coding was as good as human coding in differentiating sentiment on a 3-point scale, although we were cautious of the rather low Krippendorff's Alpha scores (Krippendorf, 2013).On this basis, automated sentiment analysis was conducted on the replies received by the China-and non-China-related bodies of tweets that contained more than three characters in the text, excluding those that contained a URL link alone.Sentiment analysis was not conducted on the #southchinasea dataset because several countries are often included in the same tweets.Since our interest is on the sentiment related to China, the analysis would not serve our purpose.

China's state media on Twitter
China's three state media accounts were very active in publishing tweets (N = 53,967), of which 52,047 were unique by content in the 389 days from 1 October 2016 to 24 October 2017.Their tweets received 255,857 replies (not counting promotions or petitions), of which 215,484 were unique by content.To the average of 4.7 replies received per tweet (4.1 unique replies to every unique tweet), the state media engaged little with them: not only did they publish few reply tweets overall (N = 1,552), the overwhelming majority of their reply tweets were made to tweets published by themselves to provide further information about their original tweets (Table 1).This suggests that, despite the interactional capabilities of social media, China's state media used Twitter predominantly as a one-way propagation platform.
The most-liked tweet published by the three in the period was @CGTNOfficial's three photographs of gold-coloured fireworks with the caption: 'Showers of molten iron, a stunning fireworks alternative, light up #China arts fest https://goo.gl/xbEr52'. 3The most-retweeted tweet came from @CGTNOfficial: '#BREAKING Thailand's King Bhumibol Adulyadej, the world's longest-reigning monarch, has passed away aged 88' 4 with four accompanying photographs.The most-replied to tweet was a three-minute video, published by @XHNews on 16 August 2017, with the caption: '#TheSpark: 7 Sins of India.It's time for India to confess its SEVEN SINS,' 5 the first of which, according to the video, was India's troops illegally crossing the border with China.It is noteworthy that two of the three tweets involved serious non-China-related international events.
Most of the popular tweets, however, were China related, and they tended to be less serious.The second most-liked tweet was a video with the caption: 'Just when you think it's a police officer who thinks he can park anywhere, this amazing moment happens.'The video shows a Chinese policeman who stops his police vehicle in the middle of the road to block all traffic and jumps out to usher an old lady across the road.The second most retweeted tweet was a caption: 'When the teacher asks you to bring a fish to class for observation and you tell your father any fish will do', 6 that accompanies a photograph which shows a large mud carp on a stainless-steel tray on a table in front of a small child and several other children sitting around the table each holding a small transparent box with a gold fish inside.An example of a popular tweet was a video with the caption: '570 meters above valley!World's highest bridge in SW China's Guizhou ready to open for #Shanghai-Kunming High-Speed Railway'. 7 The popular tweets suggest that China's news media, despite generally seen as lacking credibility, could draw user attention for other reasons.Replies made to soft items tended to be positive, indicating that users could identify with the messages.Many comments left by retweeters of the tweet about the death of Thailand's king were written in Thai, suggesting that some non-Chinese nationals used CGTN as an information source.Emotive expression of negative sentiment was mixed with appreciative responses in replies made to the tweet of fireworks photos, and the tweet on '7 sins of India' drew predominantly negative and critical replies.This suggests that at least some following of China's state media is not built on endorsement.We also found, consistent with previous studies (Bolsover, 2017), that some users used the reply function on the tweets of China's state media to vent their grievances.Notable among such responses was a campaign against an alleged fund-raising scandal at the Yunnan Kunming Fanya Non-Ferrous Metal Exchange (Radio Free Asia, n.d), which replied in Chinese.

China-related tweets
China's state media tweeted about a broad range of themes.Among the China-related tweets, President Xi Jinping was the most conspicuous theme, with #xijinping being the most frequent single word (n = 1429), and 'jinping' occurring in 299 tweets (243 of which as 'president jinping') (the software ignores words of fewer than three characters).#xijinping cooccurs most highly with 'president' (n = 823) (See Figure 1 and supplementary file for visualisations for all figures), and indeed 'president #xijinping' is the most frequently-occurring (n = 804) 2-word term (Figure 2).'New year' is the fifteenth most frequent two-word term (n = 134), and was mainly used in tweets about celebration and hope for the future in China-related tweets.The same phrase, however, is related to security concerns and accidents in addition to celebrations in non-China-related tweets, among which the term ranks sixty-fourth.Our observation found that Chinese festivities, including, for example, the Winter Solstice festival, form a consistent theme, indicating a focus on traditional Chinese culture.There is a substantial body of tweets focused on the lighter side of life in China, which may be less easily identified by keywords.Many tweets focus on beautiful sceneries, cultural heritage, and amusing moments in street life.The emphasis of China's achievements and culture by state media on Twitter echoes an earlier finding about CCTV's international channel and the China National Network (Zhang, 2009), which, together with the continued focus on the country's leaders, suggests that China's state media on Twitter are repeating the same themes as published on other platforms in their external communication.The focus on China's culture and civilization is one of the tactics recently reiterated by President Xi Jinping for China's external communication (Xinhuanet.com, 2016).There are also many cute animals (particularly giant pandas) and scientific discoveries in various parts of the world, activities of Chinese persons in foreign/international organizations (e.g. the Chinese basketball player Yao Ming in the US), and international events held in China (e.g. the world robot conference).These themes are consistent with the tactic of focusing on points of common interest between China and the West ('Xinhuanet.com, 2016).'korean president' (n = 124), North Korea, missile, Japan and security and defence issues.This mirrors international concern about test-launches of an intercontinental ballistic missile by North Korea in July 2017, and China's concern about the deployment in South Korea of the American Terminal High Altitude Area Defence (Thaad) system.

Sentiment of replies to China's media tweets
To examine the overall sentiment of replies received to the tweets from Chinese state media, the sentiment score of each of the replies after conversion was aggregated.Analysis shows that -within the limitations of reliability mentioned above-replies tend to be positive but more so towards China-related tweets than to non-China-related tweets (Table 2).Higher positivity in replies to China-related tweets may be related to the more human-interest themes in them than in non-China-related tweets.Non-China-related themes sometimes involve conflict between China and other countries (as in the '7 sins of India' tweet), which is more likely to draw critical comments.
To further understand the response of Twitter users, we analysed the sentiment of replies made to three prominent Chinese themes: Xi Jinping's visits, the Belt and Road Initiative (BRI), and giant pandas.Tweets were identified as about these themes by keywords: We are aware that the 'panda' criteria would exclude many tweets about giant pandas that contain videos and captions without the 'panda' word or hashtag, but reckon that the tweets included by the criteria are relevant for our purpose.Results show that the panda theme receives more replies per tweet than the BRI or Xi's visits (Table 2).Replies to the pandarelated theme are also more positive, particularly compared to Xi's visits.Almost 18 per cent of replies to the Xi visit theme are negative.Results of the sentiment analysis are consistent with the observation that the most popular tweets are soft news items.The results speak to the appeal of China's culture (loosely defined) -and less so its economics -compared with its politics.

#southchinasea on Twitter
Our collected #southchinasea dataset, after de-spamming, contained 71,238 messages, including 22,922 original tweets, 47,111 retweets and 1,205 replies to original tweets.To assess the relative influence of China's state media in the hashtag, we de-duplicated identical original tweets published by the same accounts to arrive at 16,854 unique original tweets by account and consolidated the Like and retweet counts around these tweets.We ranked the influence of the accounts by a score, calculated by multiplying the number of unique original tweets published by the account with the average Like count and average retweet count of the unique original tweets, and arrived at a list of top twenty accounts.

China's state media in #southchinasea
Tweeting activity China's state media were active in publishing tweets using the #southchinasea hashtag.
In the 160-day period, @PDChina published 56 unique original tweets, an average of 0.35 per day, and ranks fourth by the number of unique original tweets among the top twenty accounts.@XHNews published 53 and @cctvnews/cgtnofficial 21 unique original tweets (Table 3).In addition, CCTV published 12 and @cgtnamerica published two unique original tweets.
The tweeting level of China's state media outperformed other news media among the top 20 accounts in #southchinasea except the Moscow headquartered news agency, @SputnikInt.However, they lag far behind two non-news accounts: @9DashLine and @AsiaMTI.@9DashLine describes itself as '[f]ocused on security developments across the South China Sea and Indo-Pacific region.RT ≠ endorsement'.While its name on Twitter contains the Chinese characters equivalent to '9 dash line', which may suggest sympathy with China's territorial claims, its tweeting of reports published by news suppliers does not reveal a clearly identifiable political position.@AsiaMTI is the verified account of the Asia Maritime Transparency Initiative, formed by the Washington DC based Center for Strategic and International Studies (Table 3).Other influential accounts outside the top twenty that tweeted actively using #southchinasea include US and Chinese news and research accounts (Table 4).

'Likes' and retweets
According to Twitter data, the tweets of China's state media containing #southchinasea were very successful in fetching Likes and to a lesser extent retweets: @XHNews published the most-liked (by consolidated Like count, henceforth) original tweet (n = 2159) and the mostretweeted original tweet of all accounts (n = 507).@cctvnews (including @CGTNOfficial) published the second most-liked original tweet (n = 494), and @PDChina published the ninth most Liked tweet (n = 185).Their average Likes per tweet ranged from 92.5 to 199.3, which placed them between fifth and twelfth in ranking among the most influential twenty by average Likes of original tweets (Table 3).
@XHNews also published the most retweeted original tweet, while @cctvnews and @PDChina were among the top 11 of the 20 most influential accounts in #southchinasea considering maximum retweets.However, their rankings by average retweet count of original tweets are slightly lower (ranked 8-15 of the top 20) (Table 3).Accounts that ranked at the top of average Likes and average retweets in #southchinasea were not active tweeters of the hashtag.The account that averaged the highest Likes per tweet (n = 418.8) is the official US Navy account (@USNavy), which published only four tweets.FoxNews published one tweet, and received 317 Likes and 295 retweets, making it number two average Like and number one by average retweet in #southchinasea.However, @foxnewsvideo published two tweets but only has an average Like of 9, and an average retweet of 5. Five of the top 20 accounts in #southchinasea are run by the US news media and personnel -two accounts by Heather Nauert, a former anchor/reporter on Fox News and now spokeswoman at the US State Department (one account in her personal and the other her present official capacity), one by Fox News, one by Jim Sciutto (CNN Chief National Security Correspondent), and one by ShepNewsTeam (Fox News anchor Shepard Smith's team).Other accounts include the US Pacific Command, the Australian Foreign Minister Julie Bishop, the Russian news service @RT_com, a finance information media group in China, the Yicai Global @yicaichina, and several businesspeople (@mkopNY, @ kentkristensen1) and academics (@ianbremmer, @samirsinh189) (Table 3).Based on our score, which takes into account the tweeting level, average Likes and average retweets per tweet, XHNews ranks as the most influential, and PDChina the second most influential, of all accounts using the hashtag #southchinasea.
The most-liked tweet, which is also the most retweeted, published by @XHNews on 26 April 2017, is a two-hour video 'Chasing sunrise in #SouthChinaSea and exploring an uninhabited island'. 8It features a trip made by a male and a female journalist of Xinhua News Agency to one of the disputed Spratly Islands (called Nansha, or literally 'South Sand', Islands in the video, and falling within the 'nine-dash line'-demarcated territory claimed by China), described as administered by the Sansha city of China's southern Hainan Province -as part of a series of reports about the Belt and Road Initiative.The audience sees the sunrise over water in the China Sea as the pair introduces the importance of the area in ancient and present maritime navigation on a speedboat, and sees them examine the corals and ceramics on the beach, and the flora and fauna of the island as they walk around.It then sees the underwater world around the island after the cameraman dives in with his camera.The idyllic portrayal of the tropical island and the purported significance of the South China Sea in the maritime silk road belied the conflict behind the 2016 PCA ruling, which China rejected, and the controversy over navigational rights in the area.China's state media published seven of the ten most-liked tweets.The seven tweets talk either about the non-military aspect of the geographic area like the above one, or showcase China's naval drills.Their content contrasts with the other three tweets in the top ten, published by @USNavy, which showcases the naval might of the US.
As for attracting retweets, China's state media were less successful.Only three of the ten most retweeted original tweets were published by China's state media (all of which fall within the top ten most-liked).The other seven were published by US sources: three by @jimsciutto, two by @AsiaMTI, and one each by @FoxNews and mkopNY (Table 5).
The results suggest that in the #southchinasea hashtag, China's state media compete mainly with US sources for influence, be they non-profit organizations, news organizations or official US government bodies.Individual tweets of China's state media attracted extensive positive attention, but their average retweet count was often smaller than that of the US sources.However, the active tweeting of China's state media could enable them to exert influence in a way different from the US sources, which, except @AsiaMTI, were far less active in tweeting the hashtag.By the sheer volume of their tweets, China's state media are important shapers of the news agenda on the South China Sea dispute on Twitter.On events or issues that other sources do not tweet about, they would set the frame.This kind of influence would apply to @AsiaMTI, @9dashline, and @SputnikInt as well.
The verb that most frequently co-occurs with #china is 'warns' (n = 952) (See Figure 4).'#China warns' is the third most frequent 2-word term (n = 883), and 'warns #us' (n = 834) is the fourth most frequent two-word term after ' china sea' and 'south china', The object of China's warning is the US: '#china warns' co-occurs the most with 'warns #us' (n = 832), the fourth most frequent two-word term) -a use supported by our reading of the original tweets.
'Tension' is the noun that most frequently co-occurs with '#china' (n = 878), other than #us and 'sea'.'Tension escalating' ranks eleventh among frequent two-word terms (n = 797).At the same time, ' chinese' co-occurs with ' aircraft' in 92, and with ' carrier' in 83 tweets.The word frequencies and co-occurrences suggest that China is presented as a threatening actor in the original tweets of #southchinasea.
A number of high-frequency two-word terms such as '#us challenging', 'states #us', '#us cause', '#american researcher', 'researcher states', ' challenging actions', 'stance #china', 'indonesia takes', and 'takes stance' with similar frequencies of around 800 alerted us to identify about 800 repeats each of the following three tweets, the words within which explain the results of the theme analysis: • #American researcher #US is the Cause of the #SouthChinaSea Conflict (unique URL supplied with each tweet, as noted below) None of these 2,400 or so repeat tweets drew Likes or retweets.They were published by the same 19 accounts, which, upon checking on Twitter, have all now been suspended.Each of these 19 accounts published all of the above three tweets, with each account embedding a URL link in its tweets that was different from those used by other accounts, but all of which pointed to the same web page on the same website.This is clear evidence that systematic attempts were made to skew the news agenda on #southchinasea.The content of the '#American researcher' tweet is not favourable to the US.The '#China warns' tweet runs contrary to China's official rhetoric of 'China's peaceful rise'.The 'Tensions escalating' tweet is not in China's interest.These tweets, published by the same accounts, suggest that some force unfriendly to both the US and China seemed to be behind these attempts to skew the news agenda.Themes of all tweets in #southchinasea about China When retweets and replies are included in the analysis, the influence of China's state media, particularly @xhnews, can be seen.'#China warns' is less prominent, now being the seventh most frequent two-word term (n = 1096).Also less prominent is 'warns #us' (n = 951; rank = 14).'Tension escalating' and the other above-mentioned high-frequency two-word terms have moved to rank ninth and below.Instead, 'aircraft carrier' has become the most frequent two-word term (n = 2714), after 'china sea' and 'south china': It most frequently co-occurs with 'naval formation' (n = 547), 'chinese naval', '#china aircraft', 'carrier formation'.'@xhnews china' (n = 376), and 'carrier enters' in that order, suggesting that some of the co-occurrences come from the third most retweeted original tweet published by @xhnews.This suggests that retweeting has helped @xhnews to spread its message.'Underwater drone' is now the eighth most frequent two-word term (n = 1055) (See Figure 5), and it most frequently co-occurs with '@xhnews china' (n = 128), again suggesting that tweets published by @xhnews have influenced the prominent themes in #southchinasea to some extent.

Conclusion
To counteract Western domination of global communication, China has adopted a proactive strategy in its external communication as it grows in economic strength, and now aspires to set its own frame of global discourse.The activities of China's state media on Twitter constitute a step towards this aspiration.Our analysis of big data collected from the Twitter Open API found that the selected public accounts run by Xinhua News, People's Daily, and CCTV News/CGTN have established a significant presence in the Twittersphere in the six-and-a-half years or so since they started their accounts.Each of them has several million, some more than 10 million following accounts, the overwhelming majority of whose owners must reside outside China given the blocking of Twitter access in China.The substantial percentage of non-English replies collected in the state media dataset suggests that China's state media reach an international audience in the true sense of the term, not restricted to English-language users, while some of the following accounts might be within China as the collected non-English replies contain tweets written in Chinese characters.The state media accounts tweet actively about China and to a lesser extent, the rest of the world.Some of their tweets are highly successful in attracting Likes and retweets, and on average receive a handful of replies.
Just over 60 per cent of tweets published by China's state media focus on China, and their Twitter news agenda resembles those they publish on other platforms.It still smacks of propaganda.The Chinese president -particularly when he makes official visits -is the most prominent theme in their tweets.The Chinese premier comes second on the news agenda, while metropolises such as Beijing, Shanghai and Hong Kong are the sources of frequent stories.Achievements and developments of China are also high on their news agenda.These serious items generally do not appeal to their followers as much as soft items, which may be less prominent in the news agenda but whose popularity makes them more prominent to Twitter users.The sentiment of replies to the panda theme is more positive than to the Belt and Road Initiative or President Xi Jinping's visits.This supports the view that China's soft power varies across different spheres (Sparks, 2016), and suggests that a more nuanced analysis of China's strategy of external communication would be fruitful.
China's state media make a concerted effort to compete as global news services by devoting just under 40 per cent of their tweets to news not directly related to China.These tweets often focus on breaking news, involving disasters and accidents, or presidents of other countries.These themes are similar to those covered by Western media, and suggest that China's state media follow Western news values in their reporting of non-China-related events.
Irrespective of the interactive capabilities available on Twitter, China's state media primarily use the platform as a one-way propagation medium, and rarely engage in conversation with those who reply to their tweets.While the same lack of reader engagement is also observed in the accounts of state media on China's domestic social platform, Weibo, international social media present new challenges that may further deter their use of the interactive features.Unlike on domestic social media, where 'undesirable' messages could be censored, China's state media are not able to delete critical replies or petition tweets on Twitter that are posted as replies to their tweets.Actively responding to replies may encourage petition or promotional uses of the reply feature on Twitter, and threatens to derail the mission of building good images of China as a big nation (Xinhuanet.com 2016).
Their high volume of tweeting about China makes China's state media important shapers of the news agenda about the country on Twitter.This is clearly seen in the case study of the #southchinasea hashtag, where the three Chinese state media accounts, individually, are among the most active and influential tweeters.They rank among the top fifteen accounts with the highest average Likes and average retweets per tweet, with Xinhua News publishing the most liked and most retweeted tweet of the hashtag in the studied period.Retweets of their original tweets have helped to make the themes related to China in #southchinasea less emotive.
Compared with the two most active tweeters of the hashtag, the tweets of China's state media received more unique replies.Yet the active response to their tweets cannot be equated to Twitter users' support for their messages.Sentiment analysis of the replies received by the tweets of China's state media identifies much negativity, especially in response to tweets not related to China in content (Table 2).It is likely that among the large number of followers of China's state media accounts are some who follow to monitor their tweets with the purpose of disputing their content.
Sources from the US and China make the majority of the most influential 20 accounts in #southchinasea.While this reflects dominance of US sources on the American platform, the prominence of China's state media may not be found among issues in which China has lesser interest.Even in #southchinasea, China's sources are beaten by US sources among the top twenty, both in terms of the number of accounts (four versus seven news-related and official accounts from the US alone) and the total number of tweets published.The US think tank, AsiaMIT, published more unique original tweets on its own than the combined tally of unique original tweets published by China's four accounts, The other US accounts among the top twenty in #southchinasea tweeted far less frequently using the hashtag than China's state media, but when they did, they provoked more retweets on average than the latter.This means that China's state media have yet to upset the dominance of US sources on Twitter, as exemplified in our study of #southchinasea.
Processing the data, it emerges that systematic attempts exist in #southchinasea to skew the news agenda by repeating tweets, an activity often performed by automated bot accounts.While the manufactured tweets are fake in the sense that they do not originate from the claimed account holders, they are real in terms of their existence in the Twittersphere as published content about the South China Sea.While manufactured tweets distort user metrics, their impact on legitimate Twitter users is uncertain.Twitter users tend to get their news through scrolling their timelines or browsing tweets of those they follow more than through searches (Rosenstiel et al., 2015).The repeated 2,400 tweets discussed above, in fact, received no Likes or retweets, meaning that even if the manufactured accounts managed to draw some legitimate followers, their tweets did not engage them.Our reading of these manufactured messages suggests that some force unfriendly to both the US and China may be behind the artificial amplification of a certain agenda in #southchinasea.

Limitations of the study
Our study has provided empirical understanding of the performance of China's state media on Twitter, the international social media platform recognised for news use.We are confident that our methods and data have produced valid results, but they need to be read in context.Our analysis relies on user metrics as indicators of influence but they are liable to manipulation.While genuine retweeting indicates influence, it does not necessarily equate to endorsement of the view expressed by the original tweet.Methodologically, since '#southchinasea' was used as the keyword to collect tweets in the case study, replies that do not include the #southchinasea hashtag in the text of the reply would be excluded in the dataset.However, The most frequent theme related to the Chinese president were his visits (n = 348): #xijinping co-occurs the highest with #xivisit (n = 233) and 'visit' (n = 115).In addition, 'jinping' co-occurred with 'visit' in 45 tweets and '#xivisit' in 43.The focus of China's state media Twitter accounts on the activities of the country's top leader is consistent with the news agenda of China's traditional national media.Other themes related to #xijinping were ' cooperation' (n = 103), 'summit' (n = 86), 'ties' (n = 84), 'says' (n = 81), and ' development' (n = 70).Other prominent themes in the China-related tweets were: • Premier Li Keqiang: 'premier' n = 757, 195 of which were 'premier keqiang' and 178 of which were 'premier #likeqiang'.The themes associated with 'premier' were most often, again, 'visit' (n = 101) and ' cooperation' (n = 93).• The Belt and Road Initiative: #beltandroad n = 718.#beltandroad co-occurred most frequently with 'initiative' (n = 253), ' cooperation' (n = 115), and 'president' (n = 89).• The National Party Congress, which held its nineteenth plenary session in March 2017 (n = 651 combined: 'thcpc thpartycongress' n = 286; 'national' co-occurrence with ' congress' n = 235; 'national' co-occurrence with 'thecpc' n = 130).

Non-China-related tweetsBreaking news was the most common theme tweeted about other countries by China's state media.It is logical given the nature of social media, and the aspiration of China's state media to compete with other international media.#Breaking was the most frequent word (n = 1850), which most often co-occurs with 'says' (n = 198), 'killed' (n = 198), 'injured' (n = 165), and 'police' (n = 155) (See Figure3).'Death toll' was the third most frequent two-word term (n = 264).Another top theme of the non-China-related tweets relates to the president ('president' n = 1391) of foreign countries, which co-occurred most frequently with the US president.'Trump' occurs in 787 tweets, @realdonaldtrump 504, and #trump in 338 tweets.Many of these tweets reported what he 'said'.Russia is a country that features prominently, with 'russia' (n = 797), 'russian' (n = 715), and #russia (n = 196) being high frequency words, again involving heavily what the Russian President 'says'.The interest on foreign presidents is reflective of the importance accorded to these leaders based on elite-centric news values, consistent with what would also be covered by Western media with whom China's media compete.The theme of the US follows the importance of the country, both globally and to China in particular, whereas the coverage of Russia is correlated with the strengthened relationship between Russia and China as reflected by the multiple meetings between the two presidents in the last few years.North Korea is heavily reported ('#dprk' n = 591; ' dprk' n = 317) particularly in relation to 'missile', 'nuclear', 'test' and 'military' issues.South Korea is mainly reported in relation to
