After Didi violated China's network security law, data security law, and personal information protection law, China's Cyberspace Administration fined the company 8.026 billion yuan ($1.19 billion).
It was unclear whether the fine would allow Didi to add new users or restore its presence on China's app stores following the fine.
A Didi subsidiary was among companies fined in March by China for not complying with antimonopoly laws and failing to disclose certain transactions, including Alibaba and Tencent.
