It is the gaming companies that are responsible for compliance with the regulations, reports Reuters with reference to the state-run Chinese news agency New China.

In order to sell gaming services in China, the gaming companies must be able to guarantee that they can verify who is playing and they are not allowed to admit players under the age of 18 at times other than the permitted ones, according to the regulations.

Previous regulations limited children's online play to three hours per day on weekends and 1.5 hours per day on weekdays.

In connection with the tightening of the regulations, the Chinese authority that supervises the gaming sector will also intensify and deepen the inspections of the gaming companies, to ensure that they adhere to the regulations and have systems to counteract gambling addiction on site.
