The move marks Tencent's latest attempt to meet the Chinese government's call for tighter controls to combat gaming addiction and increasing near-sightedness among young people. A state announcement in August called for the publishing regulator to control the number of new online video games and to limit the amount of time young Chinese spend playing such games.
Tencent, the world's largest gaming company by revenue, has run into regulatory roadblocks this year and Chinese authorities have not approved any new games since March.
Without approval for in-app purchases Tencent has been unable to make money from some of its hugely popular games, such as PlayerUnknown's Battlegrounds Mobile (PUBG Mobile), which is a game that CLSA estimates could generate up to $1bn in annual revenue if given a monetisation licence.
