\nBEIJING \u2014 Three popular Chinese Internet services have been ordered to stop streaming video after censors complained it contained improper comments on sensitive issues. The move prompted a sell-off in the U. S.-traded shares of Sina Corp. and its microblogging service, Sina Weibo.
Thursday\u2019s announcement adds to efforts by President Xi Jinping \u2019s government to tighten media control ahead of a Communist Party congress late this year. Xi is due to be appointed to a second five-year term as party leader.
Video streamed by users of Sina Weibo, AcFun and Phoenix New Media\u2019s Ifeng.com contained \u201cnegative comments\u201d about unspecified sensitive issues, the State Administration of Press, Publication, Radio Film and Television said. It ordered them to stop the services.
Communist leaders promote Internet use for business and education but try to block access to material deemed subversive or obscene.
Beijing has been especially wary of social media since some sites were used by organizers of the Arab Spring protests that spread across the Middle East in 2010 and led to the downfall of the Egyptian and Tunisian governments.
Rules that took effect June 1 bar private or foreign companies from directly disseminating news or investing in online news services. Those that want to work with foreign partners must undergo a security review.
In January, the government announced a 14-month crackdown on cloud-hosting and content-delivery services. The technology ministry said it forbids use of virtual private networks and leased lines to circumvent government filters and access banned websites abroad.
On the Nasdaq Stock Market, Weibo shares fell 6.1 percent and shares of Sina fell 4.8 percent after Thursday\u2019s announcement. Both regained less than 1 percent Friday.
\u201cThe company is communicating with the relevant government authorities to understand the scope of the notice. It intends to fully cooperate with the relevant authorities, \u201d Weibo said.
Sina Weibo\u2019s main business is a microblogging service similar to Twitter. It is one of the world\u2019s most popular social media services, with 313 million users as of December, according to the company.
Weibo\u2019s stock market value surpassed Twitter\u2019s early this year. It stood at $15.8 billion after Thursday\u2019s sell-off \u2014 or more than double the $6.2 billion market value of its parent company \u2014 compared with $13.2 billion for Twitter.
AcFun is a video-sharing site that is popular with young Chinese, and Ifeng broadcasts brief news and entertainment videos.
In a statement on its Weibo account, AcFun promised to carry out a \u201ccomprehensive rectification\u201d of its website management to create a \u201cclear and bright online environment.\u201d<\/p>\n
