The company has faced criticism in the United States over potential ties to the Chinese government that could enable surveillance. In 2017, ZTE was fined for illegally exporting U.S. technology to Iran and North Korea in violations of economic sanctions. In April 2018, after the company failed to properly reprimand the employees involved, the U.S. Department of Commerce banned U.S. companies (semiconductors) from exporting to ZTE for seven years. The ban was lifted in July 2018 after ZTE replaced its senior management, and agreed to pay additional fines and establish an internal compliance team for 10 years. In June 2020, the Federal Communications Commission designated ZTE a national security threat, thereby barring it from any U.S. subsidies.
