Beijing, Dec 2 (IANS): China's ministry of culture Tuesday announced a list of internet firms, including Tencent and Baidu, which are suspected of spreading pornography and gambling.

Mobile game platforms run by the two firms and nine other internet companies were alleged to be involved in pornography, gambling and violence, Xinhua reported citing a ministry statement.

The statement also chastised comic and animated products on 21 websites provided by companies, including China Telecom and Tencent, for containing bloody, terror and violent content.

The document added that some products seemed to be intentionally playing the pornography card, challenging accepted moral values.

The companies will be fined and the amounts published later, said Liu Qiang, a deputy director in the market department of the ministry.

Liu said the ministry planned to establish a blacklist of companies that repeatedly break rules and impose harsher punishments on them.

"We hope that major companies can shoulder their due social responsibilities and offer healthy, quality, cultural products," said the official.
