China to launch cybersecurity probe into more Us firms after cracking down DiDi

On Monday, China's cyberspace watchdog said it is investigating online recruiter Zhipin, and truck-hailing apps Huochebang and Yunmanman, ramping up a crackdown on the mainland's tech companies amid tightened regulations on data security.

The announcement comes a day after the Cyberspace Administration of China (CAC) ordered a suspension of app downloads for Chinese ride-hailing giant Didi Global, which went public in a US listing last month.

Full Truck Alliance, the result of a merger between Huochebang and Yunmanman, and Kanzhun, the owner of Zhipin, went public in the US stock market last month.

The three app-based businesses should halt new user registrations during the review, the CAC said in a statement, adding that the investigations are to "prevent national data security risks and safeguard national security".

The cyberspace agency did not offer further details about the investigation into the three apps but cited China's national security law and cybersecurity law.
