Last year, around this time, Huawei was put on an Entity List by the U.S. Department of Commerce that banned it from dealing with any U.S. company. Among other repercussions, the move led Google to revoke Huawei's Android license meaning it could no longer launch new Android products with Google's Play suite pre-loaded. The ban by the U.S. government has now been extended through 2021.
In May 2019, Trump signed an executive order declaring a national emergency and preventing U.S. companies from using telecom equipment from selected companies as they posed a threat to national security. Apart from Huawei, the ban also affected ZTE and a few other Chinese companies. In order to avoid major disruptions, the U.S. Commerce of Department has been issuing temporary licenses to Huawei that allow it to procure products from U.S. companies and the latter to obtain some products from it. That license is set to expire in a few days, though it is expected to be renewed again. Back in March, the wireless trade association CITA had asked the commerce department for a "long-term" license extension for Huawei given the current scenario worldwide.
The Federal Communications Commission has marked Huawei and ZTE as national security risks that prevent customers of these companies in rural America from using an $8.5 billion government fund to buy their equipment.
