China's Ministry of Culture has issued new regulations banning children from using virtual currency to buy items in games.
The controls are made possible by a requirement that online game players register with their real names.
Minors will be banned from buying or selling items with virtual currencies, although the purchase of "products or services" will be allowed.
Game companies will be required to develop "techniques" limiting children's gaming time in order to prevent addiction, an issue which has been in the headlines in China since a series of deaths among "internet-addicted youths" last year. But the techniques, or the amount of gaming time, aren't specified.
The Ministry also requires companies to develop means to keep children from playing "inappropriate games", forbidding online games from including content that involves pornography, cults, superstition, gambling and violence.
