Explained | Why and how China is drastically limiting online gaming for under 18s

China on Monday introduced new rules that limit the amount of time under-18s can spend on video games to three hours a week, a move it said was necessary to combat gaming addiction. The National Press and Publication Administration, the regulator which approves video game titles, said on Monday the new rules were a response to growing concern that games affected the physical and mental health of children. About 62.5% of Chinese minors often play games online, and 13.2% of underage mobile game users play mobile games for more than two hours a day on weekdays, according to state media. In 2017, Tencent Holdings said it would limit play time for some young users of its flagship mobile game "Honor of Kings", a response to complaints from parents and teachers that children were becoming addicted.
