Beijing's pervasive policing of cyberspace and attempts to block the Internet are already among the world's most stringent. The Ministry of Public Security said the "purification of the Internet" and fighting of online crime are closely tied to the country's stability. Nearly 9,000 pornographic Web sites have been deleted from the Internet and 5,394 suspects captured in 2009, although it did not say how many of them were formally arrested or charged; but have vowed to strengthen Internet policing .

It said future efforts would focus on China-based operators of overseas-registered Web sites and companies that provide Internet services, or register domain names or rent virtual space to sites with pornographic content. It also says the main targets of its Web censorship are pornography, gambling and other sites deemed harmful to society.

Porn internet surfing is long regraded as a privilege for the communist party officials in China and allow thousand or possibly million of 'horny' Chinese unlimited free access is against the national interests, claims one high ranking communist official.

Critics, however, say that often acts as cover for detecting and blocking sensitive political content. Its restrictions of the Internet are often referred to as the "Great Firewall of China."

Many foreign sites have been blocked by China's Internet authorities, including YouTube, Facebook, Twitter and a host of other media and news Web sites.

Last year, China backed down from a requirement for new computers to be loaded with a controversial Internet-filtering software known as Green Dam Youth escort after a major outcry from Chinese citizens and computer companies.
