US shuts ‘secret backdoor’ that may have allowed Chinese companies to use Nvidia’s top AI chips

The US government has rushed to close a major security loophole that accidentally allowed Chinese tech firms to use the world’s most powerful artificial intelligence chips for nearly a year, a report has said. The US Department of Commerce issued a guidance on Sunday (May 31), shutting down a ‘secret backdoor’ that may have let foreign subsidiaries of Chinese companies bypass strict American trade bans, as er a report by news agency Reuters.

For the past year, the US has tried to block China from accessing Nvidia’s semiconductors needed to build advanced military and commercial AI.
