BEIJING, Sept. 28 (Xinhua) -- The Ministry of Culture is planning to check 200 randomly-selected online games operators, after giving dozens of warnings for various violations.

The ministry will personally examine 50 operators, while authorities in Beijing, Shanghai, Guangzhou, Shenzhen and Hangzhou will review 30 each, the ministry said Wednesday.

The 200 targets account for about 13 percent of online game operators in the country.

The checks will focus on operators that use banned content, import games without approval, are unlicensed, or fail to use real-name registrations for players.

Last month, the ministry urged 26 operators to rectify violations, such as providing games using pornography, gambling, or that going against social ethics, as well as failing to take measures to prevent children becoming game addicts.

In China, online game operators must prevent minors from playing too long, and use measures such as reducing or even invalidating their in-game gains after a set time-limit.

The ministry said it planned to launch similar inspections on a regular basis, covering all game operators within two years, with more frequent checks on repeat offenders and targets of multiple public complaints.
