The Trump administration’s immediate focus is tightening restrictions on Huawei Technologies Co., the giant Chinese telecommunications company that the White House and Congress view as a national security threat. The Commerce Department recently sent to the Office of Management and Budget new regulations that would largely eliminate a loophole that allowed U.S. companies to sell to Huawei from their overseas facilities, said people familiar with the actions.
Some lawmakers and national-security experts say Huawei’s equipment would allow Chinese leaders to spy on Americans, which the company has regularly denied. A Huawei spokesman didn’t immediately return a request for comment on the potential restrictions.
