The Chinese government has ordered China's top ten websites to work together to fight the piracy of Olympic material, according to the state-run Xinhua News Agency.

Sina, Netease, official Olympic website Sohu and six other sites signed an agreement with China Central Television (CCTV), which is the games' official internet broadcaster in China, stating they will not provide video, images or content that would violate CCTV's rights, nor will they provide links to such material.

The State Administration of Radio, Film and Television, China's internet and broadcast content regulator, has ordered all websites to respect CCTV's broadcast rights, online and offline.

CCTV, also China's top broadcaster and domestic licensee for the 2008 Olympics, has partnerships to provide online and mobile content to 160 websites, in China and the Macau Special Administrative Region, west of Hong Kong.

The move may have come in part because of the filming and broadcast of rehearsals of the opening ceremonies by a Korean news team from Seoul Broadcasting System (SBS), a move that incensed the Beijing Organizing Committee for the Games of the XXIX Olympiad (BOCOG).

The 2008 Olympics begin Friday night in Beijing, and run through August 24.
