The Bureau of Industry and Security, the national security arm of the U.S. Department of Commerce, has announced it will be adding Huawei and its affiliates to the Bureau’s “Entity List.”

The action stems from “information available to the Department that provides a reasonable basis to conclude that Huawei is engaged in activities that are contrary to U.S. national security or foreign policy interest.” This information includes alleged violations of the International Emergency Economic Powers Act, conspiracy to violate IEEPA by providing prohibited financial services to Iran, and obstruction of justice in connection with the investigation of those alleged violations of U.S. sanctions.
