China bans tech companies from buying Nvidia’s AI chips

China’s internet regulator has banned the country’s biggest technology companies from buying Nvidia’s artificial intelligence chips, as Beijing steps up efforts to boost its domestic industry and compete with the US.

The Cyberspace Administration of China (CAC) told companies, including ByteDance and Alibaba, this week to end their testing and orders of the RTX Pro 6000D, Nvidia’s tailor-made product for the country, according to three people with knowledge of the matter.
