Fellow tech company Intel ‘reviewing regulations’ as timing of move brought forward

The chip designer Nvidia has said the US has told it to immediately halt the export of some of its high-end artificial intelligence chips to China as regulators advanced the deadline.

The restrictions were supposed to come into effect 30 days after 17 October, when the Biden administration announced measures to stop countries, including China, Iran and Russia, from receiving advanced AI chips designed by Nvidia and others.
