The total number of porn websites blocked in China has reached 726, with the imposition of ban on another 244 sites last week.
The Government crackdown on porn websites had begun on January 5, according to Xinhua news agency.
A statement issued by the Special Operation Office for Crackdown on Online Porn and Lewd Content revealed that about a third of the closed websites had not registered with governmental departments, reports the China Daily.
The statement further added that such websites violated the top legislature's regulations, and other laws regarding public distribution of sexual images.
