U.S. moves to cut off chip supplies to Huawei

The Trump administration said it would impose export restrictions designed to cut off Chinese telecom-equipment maker Huawei Technologies Co. from overseas suppliers, threatening to ignite a new round of U.S.-China economic tensions.

The restrictions stop foreign semiconductor manufacturers whose operations use U.S. software and technology from shipping products to Huawei without first getting a license from U.S. officials, essentially giving the U.S. Commerce Department a veto over the kinds of technology that Huawei can use.

The restriction further tightens the U.S. export-control system’s existing rules related to Huawei. Washington alleges that Huawei gear could be used by Beijing to spy globally, which Huawei has repeatedly denied.
