Telecommunications Denial Order Enforcement Act This bill directs the President to determine annually whether telecommunications companies domiciled in China, including Huawei and ZTE, have violated U.S. export controls or sanctions. If a violation is found, the President must impose appropriate penalties. Chinese subsidiaries of foreign companies are excluded from the bill. The bill also prohibits executive agencies from reducing any penalty imposed on a Chinese telecommunications company for violating a sanction or export control, unless the President certifies that the company has not violated U.S. law for at least one year and is fully cooperating with investigations.
