China Accuses U.S. of Abusing WTO National Security Exceptions

China accused the U.S. of abusing a national security exception at the World Trade Organization by cutting off Huawei Technologies Co. to American suppliers and warned the move could have grave consequences for the global trading system.

At a meeting of the WTO’s Committee on Market Access in Geneva on Tuesday, China said the U.S. had violated WTO rules and urged the Trump administration to “immediately lift all unilateral sanction measures against Chinese companies.”
