Trump administration tightens restrictions on Huawei

What they're saying: The Commerce Department says Monday's action will "prevent Huawei's attempts to circumvent U.S. export controls to obtain electronic components developed or produced using U.S. technology."

• This May, Commerce amended a rule to go after Huawei's acquisition of semiconductors that use U.S. technology and software. Monday's announcement tightens that rule.
• “As we have restricted its access to U.S. technology, Huawei and its affiliates have worked through third parties to harness U.S. technology in a manner that undermines U.S. national security and foreign policy interests," Commerce Secretary Wilbur Ross said. "This multi-pronged action demonstrates our continuing commitment to impede Huawei’s ability to do so.”
