China unveiled tighter Internet controls on Friday, legalizing the deletion of posts or pages which are deemed to contain "illegal" information and requiring service providers to hand over such information to the authorities for punishment.
The rules signal that the new leadership headed by Communist Party chief Xi Jinping will continue muzzling the often scathing, raucous online chatter in a country where the Internet offers a rare opportunity for debate.
The new regulations, announced by the official Xinhua news agency, also require Internet users to register with their real names when signing up with network providers, though, in reality, this already happens.
Chinese authorities and Internet companies such as Sina Corp have long since closely monitored and censored what people say online, but the government has now put measures such as deleting posts into law.
"Service providers are required to instantly stop the transmission of illegal information once it is spotted and take relevant measures, including removing the information and saving records, before reporting to supervisory authorities," the rules state.
