HONG KONG -- Shares in China's biggest gaming companies plunged in Hong Kong on Friday after Beijing issued draft regulations aimed at curbing players' spending, with $46 billion wiped off Tencent Holdings' market capitalization.
All online games will be required to set limits on users recharging their accounts, and pop-up alerts should be used to warn and remind users of "irrational spending," according to the draft rules issued by the National Press and Publication Administration, China's gaming regulator.
