[JURIST] Chinese officials have ordered the closure of 25 video-sharing websites in a recent crackdown on Internet content considered pornographic, violent, or a threat to national security, the Chinese State Administration of Radio, Film and Television [official website, in Chinese] said Friday. Under rules that went into effect earlier this year, Chinese video-sharing websites must delete and report any content that falls into one of the prohibited categories. Chinese officials also plan to penalize 32 other websites that violated these rules, including the popular Chinese video-sharing website Tudou [corporate website].

On Sunday, China blocked access [JURIST report] to the video-sharing website YouTube [corporate website] after videos of a recent government crackdown [YouTube videos] on Tibetan protesters challenging Chinese rule were posted on the website. AP has more.
