US tightens chip curbs on China in major crackdown

The United States has imposed its third major round of export controls on China’s semiconductor industry in three years, targeting 140 companies with restrictions on chipmaking equipment, software, and advanced memory chips. Among those affected are prominent firms like Naura Technology, ACM Research, and SiCarrier Technology, as well as entities linked to Huawei, a key player in China’s chip advancements.

The measures, aimed at stalling China’s progress in AI and military technologies, also introduce new licensing requirements for US and foreign companies shipping equipment with US components to China. Commerce Secretary Gina Raimondo stated the restrictions are intended to block China’s military modernisation. Despite the sanctions, Chinese officials condemned the move as “economic coercion” and vowed countermeasures.

The rules also impact allies, with restrictions extending to chipmaking equipment from countries like Singapore and South Korea, while Japan and the Netherlands are exempt. Some global players, including Dutch firm ASML, downplayed the immediate impact but acknowledged potential long-term effects. These actions come as China accelerates efforts toward self-sufficiency in semiconductor production, though it remains years behind industry leaders like Nvidia and ASML.

This latest crackdown follows the sweeping 2022 curbs on high-end chips and manufacturing tools under the Biden administration, reflecting a sustained US effort to curtail China’s access to critical technologies.
