Shares of Chinese videogame giants Tencent Holdings Ltd. and NetEase Inc. dropped Thursday, after authorities summoned the companies and ordered them to follow new rules for the online-gaming industry.
The two companies and others were ordered to follow recent regulations imposing much tighter restrictions over minors’ playing time, to step up content control and censorship, and to refrain from unfair competition, the state-owned news agency Xinhua said.
