Chinese authorities have removed 13,175 websites as part of a national campaign against pornography on the Internet, xinhuanet.com reported Tuesday.

The China Internet Network Information Center (CNNIC) said that since Dec. 9, 3,015 websites were turned in by reports and 10,160 others were caught by the screening of the register agencies.

The Internet center is screening the 13 million CN domains, of which 2618 were removed for being pornographic. The illegal application rate of CN domains has narrowed down from 25 percent to 15 percent, said an Internet center official.
