History

Historical Context

In August 2018 the U.S. NDAA barred federal use of Huawei and ZTE gear, and on 15 May 2019 the Commerce Department added Huawei and 70 foreign subsidiaries to the Entity List, cutting off U.S. technology sales. That precedent shapes today’s debate over Moonshot AI’s China-made Kimi K3 model, as the Trump administration again weighs export restrictions that could echo the earlier market shock.
