Huawei 5G Ban (2019)
May 2019What Happened
The Trump administration added Huawei to the Commerce Department Entity List and effectively banned the company from U.S. telecommunications networks, cutting off access to Google services and American chip suppliers. The action extended globally as the U.S. pressured allies to exclude Huawei from 5G infrastructure.
Outcome
Huawei's smartphone business collapsed outside China, losing access to Google's Android services. The company stockpiled chips before restrictions tightened.
The ban reshaped global telecommunications supply chains. European carriers faced costly Huawei equipment removal. China accelerated domestic semiconductor development. The precedent established a template for technology decoupling.
Why It's Relevant Today
The DJI ban follows the same playbook: national security justification, Covered List mechanism, exemption of existing equipment, and pressure on domestic alternatives to fill the gap. The Huawei case shows both the feasibility and the costs of such restrictions.
