China reportedly issued new rules today forbidding minors from playing video games more than three hours a week, while banning youth gaming entirely from Monday to Thursday. While some news reports say the ban applies to all video games, enforcement measures issued by the National Press and Publication Administration (NPPA) primarily target online games and online services related to gaming.

"Gaming companies will be barred from providing services to minors in any form outside the stipulated hours and must ensure they have put real-name verification systems in place, said the regulator, which oversees the country's video games market," a Reuters article said. "Previously, China had limited the length of time under-18s could play video games to 1.5 hours on any day and three hours on holidays under 2019 rules."
