BEIJING - China set new regulations on Internet news content on Sunday, widening a campaign of controls it has imposed on other Web sites, such as discussion groups.

"The state bans the spreading of any news with content that is against national security and public interest," the official Xinhua news agency said in announcing the new rules, which took effect immediately.

The news agency did not detail the rules, but said Internet news sites must "be directed towards serving the people and socialism and insist on correct guidance of public opinion for maintaining national and public interests."
