U.S. revokes some licenses for exports to China's Huawei

WASHINGTON — The United States has revoked some export licenses that allowed companies such as US chip firm Qualcomm to supply Chinese tech giant Huawei, the Commerce Department confirmed on Wednesday.

The move adds pressure on Huawei, which has long been caught in an intense technological rivalry between Beijing and Washington over U.S. fears it could be used for Chinese espionage operations.
