The agency also expanded existing controls on chipmaking gear, including products made by US firms at foreign facilities, but with carveouts for key allies, such as Japan and the Netherlands. That comes after months of negotiations between Washington, Tokyo and the Hague, during which Biden officials floated — but ultimately did not pursue — applying US controls to companies like Tokyo Electron Ltd. and ASML Holding NV.
The US unveiled new restrictions on China’s access to vital components for chips and AI, escalating a campaign to contain Beijing’s technological ambitions but stopping short of earlier proposals that would have sanctioned more key Chinese firms.
The Department of Commerce slapped fresh curbs on the sale of high-bandwidth memory chips made by US and foreign companies, likely affecting South Korea’s SK Hynix Inc. and Samsung Electronics Co. as well as Idaho-based Micron Technology Inc. Those components handle data storage and are essential for AI applications.
