or shut down internet access in response to incidents it deems a risk to national security. For example, in response to the 2009 riots in Xinjiang, the Chinese government restricted internet access in the region and shut down the social media platforms Twitter and Fanfou. In May 2022, outspoken market strategist Hong Hao's social media accounts in China (Weibo & WeChat) were suspended due to series of negative commentaries regarding the country's two-year slump on COVID-19 lockdowns and political tensions. Text messaging According to Reporters without Borders, China has over 2,800 surveillance centers devoted to text messaging. As of early 2010, cell phone users in Shanghai and Beijing risk having their text messaging service cut off if they are found to have sent "illegal or unhealthy" content. In 2003, during the severe-acute-respiratory-syndrome (SARS) outbreak, a dozen Chinese people were reportedly arrested for sending text messages about SARS. Skype reported that it was required to filter messages passing through its service for words like "Falun Gong" and "Dalai Lama" before being allowed to operate in China. During protests over a proposed chemical plant in Xiamen during the summer of 2007, text messaging was blocked to prevent the rallying of more protesters. Video games In 2004, the Ministry of Culture set up a committee to screen imported online video games before they entered the Chinese market. It was stated that games with any of the following violations would be banned from importation: Violating basic principles of the Constitution Threatening national unity, sovereignty, and territorial integrity Divulging state secrets Threatening state security Damaging the nation's glory Disturbing social order Infringing on others' legitimate rights The State General Administration of Press and Publication and anti-porn and illegal publication offices have also played a role in screening games. Examples of banned games have included: Hearts of Iron (for "distorting history and damaging China's sovereignty and territorial integrity") I.G.I.-2: Covert Strike (for "intentionally blackening China and the Chinese army's image") Command & Conquer: Generals – Zero Hour (for "smearing the image of China and the Chinese army") Battlefield 4 (for "smearing the image of China and endangering national security") The historic ban of major video game consoles in the country was lifted in 2014 as part of the establishment of the Shanghai Free-Trade Zone. Consoles had been banned under a rule enacted in 2000 to combat the perceived corrupting influence of video games on young people.
