China boosts localisation after US chip curbs

Chinese semiconductor firms targeted by new US export controls are doubling down on localising their supply chains and leveraging stockpiled resources to maintain production. The restrictions, the third major US crackdown in three years, impact 140 companies and focus on chipmaking equipment, software, and high-bandwidth memory. Despite the curbs, Chinese chip stocks saw slight gains as analysts noted the measures were less severe than expected.

Key companies like Naura Technology and Empyrean have vowed to accelerate domestic technology development. Some, such as Beijing Huafeng Test & Control Technology, reported fully localised supply chains. While the measures hit China’s reliance on foreign manufacturing equipment, imports of semiconductor machinery surged by a third this year, showing resilience in the face of external pressures.

The exclusion of ChangXin Memory Technologies (CXMT), a major AI chip component maker, surprised analysts. The move eased concerns for South Korean suppliers reliant on Chinese revenue, with shares of key partners like Jusung Engineering and Mirae Corp rebounding. The latest curbs reflect ongoing efforts to balance US security goals with the global semiconductor market’s interdependencies.
