US Internet giants Yahoo and MSN confirmed Friday they had signed a code of conduct for their blogging operations in China that committed them to protecting the interests of the Chinese state.
Yahoo, Microsoft's MSN and other blog providers in China this week signed the "self-discipline" pact, under which they pledged to "safeguard state and public interests," according to a statement from the China Internet Society.
The pact "encourages" the Internet firms to register the real names, addresses and other personal details of the bloggers, and then keep this information.
The firms also committed to delete any "illegal or bad messages", according to a copy of the pact posted on the society's website.
Along with sex and violence, China's communist rulers have also deemed that opinions critical of it or the spreading of democratic ideology are not allowed.
Yahoo China and MSN told AFP they had signed the pact, but did not give any further comment.
"I can confirm that we signed the pact this week," Yahoo China's Beijing-based spokesman Dou Xiaohan said.
