(Reuters) -China's internet regulator has instructed the nation's biggest technology firms to stop buying all of Nvidia's artificial intelligence chips and terminate their existing orders, the Financial Times reported on Wednesday.

The Cyberspace Administration of China (CAC) directed companies including ByteDance and Alibaba this week to terminate their testing and orders of the RTX Pro 6000D, the report said, citing three people with knowledge of the matter.

Reuters couldn't immediately verify the report.
