China stops online video streaming, jolting investors

In response to censors' complaints regarding improper comments about sensitive issues, three popular Chinese internet services have been ordered to stop streaming video. The move prompted a sell-off in the US-trade shares of Sina Corp. and its microblog service, Sina Weibo.

Authorities said on Thursday video streamed by users of Sina Weibo, ACFUN and a website of Hong Kong-based Phoenix TV contained "negative comments" about unspecified sensitive issues.
