(Yicai Global) Oct. 29 -- Tencent Holdings' internet services unit Shenzhen Tencent Computer System has run afoul of China's industry and information technology ministry, which slammed it with a fine and entered it onto a list of bad operators for unlicensed business dealings, exceeding its scope of business, failure to cooperate with oversight and inspections, and violations of the real name system, the ministry announced today on its official website.

The regulator also imposed fines on 20 other internet services firms, which it likewise added to its rogues roster in the third quarter.

Tencent Computer System also swallowed a CNY50,000 fine for unfair competition on March 18, data on company data search portal Tianyancha show.

Tencent Computer System supplies internet services in the form of online communication, entertainment, and advertising, along with other internet value-added services, public information shows.
