US tries to maintain supply chain after imposing export curbs on China chips

The US is scrambling to tackle unintended consequences of its new export curbs on China’s chip industry that could inadvertently harm the semiconductor supply chain, people familiar with the matter said.

By late Tuesday, hours before a new restriction took effect, South Korean memory chipmaker SK Hynix Inc said it got authorization from the United States to receive goods for its chip production facilities in China without additional licensing imposed by the new rules. The Biden administration had planned to spare foreign companies operating in China such as SK Hynix and Samsung Electronics Co from the brunt of new restrictions, but the rules published Friday did not exempt such firms.
