BBC:

Chinese technology giant Tencent is introducing tough new rules to identify under-age gamers, amid a crackdown on gaming addiction in the country.

From mid-September it will introduce a real-name registration system for its Honour of Kings games, which will be linked to China’s public security database.
It will identify children and restrict the time they spend on the game.

The move is the first of its kind in the world’s largest gaming market.

Tencent, which also operates the Chinese social network WeChat, posted its first profit decline since 2005 this summer, blaming the drop on tighter regulation, specifically around the approval of licences that allow companies to make money from new mobile games.
