U.S. chip export controls limit China’s access to advanced computing

U.S. export controls target China’s access to advanced semiconductors and the tools needed to manufacture them, rather than imposing a blanket ban on chip sales. Administered by the Commerce Department’s Bureau of Industry and Security, the restrictions aim to slow military modernization by limiting capabilities used in AI, supercomputing and advanced weapons.

The rules cover high-performance computing chips, semiconductor manufacturing equipment and software, and support by U.S. persons for certain advanced chip facilities in China. The Foreign Direct Product Rule extends U.S. jurisdiction to certain foreign-made products based on American technology or software, bringing overseas manufacturers into the licensing framework.

Companies exporting, reexporting or transferring controlled items to restricted entities or end uses must seek authorization. Many applications involving advanced computing and semiconductor end uses in China face a “presumption of denial.” Less-advanced chips outside the restrictions can still be sold without these licensing requirements.

NVIDIA and AMD developed lower-performance chips for the Chinese market in response to the controls. Equipment suppliers including Applied Materials, Lam Research and ASML also faced reduced access to China’s advanced fabrication plants, while Beijing intensified efforts to build a domestic semiconductor equipment industry. Regulatory updates have expanded equipment restrictions, requiring companies across the supply chain to reassess compliance.
