China has put more than 4.65 million computers in over 81,000 Internet cafes across the country under watch to crack down on illegal online games, according to Minister of Culture Cai Wu.

In an interview with Xinhua, Cai said the ministry has closed 219 illegal Internet games with lewd, pornographic and violent contents, and has blocked the access to illegal games and relevant websites for more than 87 million times since the beginning of this year.

China launched a series of nationwide campaigns to crack down on the spread of lewd and pornographic contents through the Internet and mobile phones in 2009.

In the latest development, the Ministry of Public Security said on Thursday that the ministry has closed down more than 2,300 WAP websites accessible by mobile phones, and arrested 34 people for running those websites.

Cai said the culture ministry would set up laws and regulations on Internet games in order to strengthen administration in the sector, and would improve censorship of the games in the future.
