Tencent was largely spared the massive fines slapped on its peers Alibaba Group Holding Ltd. and Meituan, but the Shenzhen-based technology company was hit by new restrictions in the gaming sector. Chinese authorities introduced strict rules last August limiting the time minors' could spend playing videogames to curb videogame addiction, and what officials view as responsible for a host of societal ills, including distracting young people from school and family responsibilities. Tencent, which gets a large part of its sales from videogames, said growth in its domestic games revenue weakened to 1%, while revenue from another key business segment, online advertising, fell 13%, as China's wide-ranging regulatory actions last year hurt demand from advertisers across industries, particularly those in the after-school-tutoring and internet-services sectors.
