The Cyberspace Administration of China (CAC) has received filings from 26 app stores operated by companies like Tencent, Huawei, Ant Group, Baidu, Xiaomi, and Samsung.

China’s cyberspace regulator has released the names of the first batch of mobile app stores that have completed filing business details to regulators, signaling it has begun to enforce new rules that expand its oversight of mobile apps. This comes as Beijing has been expanding oversight of smartphone and mobile app usage over the past several years.

The Chinese Ministry of Industry and Information Technology has issued a notice requiring mobile app filing by March, prompting companies like Tencent and Huawei to demand compliance. Apple’s compliance could result in app removal.
