Its reliance on U.S. semi-conductors is a crucial point of leverage for the U.S., both in its attempt to limit Chinese influence from 5G and in the broader U.S.–China trade dispute. Recent restrictions on U.S. exports and on U.S. sales to China's foreign semiconductor suppliers such as Taiwan Semiconductor Manufacturing Co. risk undermining U.S. manufacturers' sales and competitiveness in China's burgeoning market.
