Tightening the Reins on China’s Chipmaking Ambitions

The United States has unveiled its third major effort in recent years to limit China’s access to advanced semiconductor technology. This latest crackdown imposes export restrictions on 140 companies, including Chinese semiconductor toolmakers such as Naura Technology Group, Piotech, ACM Research, and SiCarrier Technology. The restrictions also target advanced memory chips and additional chipmaking tools.

This move is aimed at curbing China’s progress in developing semiconductors for artificial intelligence (AI) and military applications, aligning with US national security concerns.

Expanding the Entity List

Nearly two dozen semiconductor firms, over 100 chip toolmakers, and three investment companies have been added to the US Entity List, requiring special licenses for US suppliers to export goods to them. Among these are firms linked to Huawei Technologies, such as Swaysure Technology and Shenzhen Pensun Technology.

The Entity List now also includes private equity and tech firms like Wise Road Capital and Wingtech Technology, cited for aiding China’s efforts to acquire sensitive chipmaking capabilities abroad.

Global Impact and Reactions

The new restrictions could significantly affect US toolmakers like Lam Research and Applied Materials, as well as non-US firms, including Dutch semiconductor equipment maker ASM International.

The rules extend to equipment produced in allied countries like Israel, South Korea, and Singapore, though Japan and the Netherlands are exempt. This expanded foreign direct product rule also allows the US to regulate foreign items containing any US chip content when shipped to China.

Chinese officials have condemned the measures, labeling them as “economic coercion” that disrupt global supply chains. In response, China is accelerating efforts toward self-sufficiency in semiconductor production, though it remains behind global leaders like Nvidia and ASML.

Memory Chip Restrictions

The restrictions also cover high-bandwidth memory (HBM) chips, vital for AI applications. Technology such as “HBM 2” and higher, produced by Samsung, SK Hynix, and Micron, faces new controls. Samsung, with around 20% of its HBM sales tied to China, is expected to be the most affected.

Broader Implications for Allies

The new rules come after extensive discussions with Japan and the Netherlands, which play pivotal roles in advanced chipmaking equipment production. The Dutch government has stated it will evaluate the restrictions, and ASML has indicated that it sees no immediate material impact but acknowledges potential effects if similar assessments are made by the Dutch government.

Countries adopting similar controls may receive exemptions, aligning them with US security measures.

Strategic Continuity

This package represents the Biden administration’s ongoing strategy to constrain China’s technological advancements. It builds on prior measures, including sweeping controls implemented in 2022, marking a significant shift in US tech policy toward China since the 1990s.
