U.S. officials moved Friday to cut off Chinese tech giant Huawei from global chipmakers, ramping up sanctions on the company seen by Washington as a national security risk.
The move is part of a ramping-up of attacks on China, with Donald Trump and his administration accusing it of being culpable for the spread of coronavirus.
Hostility to China is set to be a central theme in his re-election campaign.
The Commerce Department said it was broadening its sanctions enforcement to include semiconductor designs that are developed using US software and technology.
