Since late last year, Chinese internet regulators have cracked down more sharply on the country"s tech giants for violations of rules. The Global Times, a tabloid published by the ruling Communist Party"s official People"s Daily newspaper, said in a Chinese-language commentary on Monday that Didi"s apparent "big data analysis" capability could pose risks to the security of individuals" personal information.
