The U.S. Commerce Department has expanded its export controls on 140 Chinese technology companies, restricting access to essential equipment and software for semiconductor manufacturing. This decision is part of an ongoing effort to mitigate national security risks associated with advanced technologies. The revised entity list includes firms primarily based in China, as well as subsidiaries located in Japan, South Korea, and Singapore. These measures aim to limit China’s ability to produce advanced semiconductors critical for artificial intelligence applications.
U.S. expands export controls on 140 Chinese tech firms
The recent actions by the U.S. reflect a significant escalation in efforts to restrict China’s access to critical technology. Among the companies added to the entity list is Naura Technology Group, a key player in semiconductor manufacturing. The new measures encompass not only companies that produce computer chips but also manufacturers of the sophisticated equipment necessary for chip production. This move signals a broader strategy to close off avenues for Chinese firms to leverage U.S. technology for military advancements and other uses deemed threatening to U.S. interests.
High-bandwidth memory chips, essential for processing large data sets in AI systems, have also come under tighter controls. The new rules limit exports of these components to China, directly affecting manufacturers like Samsung and Micron Technology, which produce the cutting-edge HBM technology vital for AI training and operations. As a result, firms manufacturing semiconductor fabrication equipment, such as Lam Research and KLA Corp, may see repercussions from these restrictions.
China’s Commerce Ministry has responded to the expanded controls with strong objections, labeling the measures as economic coercion and a violation of market principles. The ministry stated that it would take actions to safeguard China’s rights and interests, although specific details on these counteractions remain undisclosed.
The U.S. administration, through statements from Commerce Secretary Gina Raimondo and Matthew S. Axelrod, emphasized that these measures are crucial for national security. Axelrod noted that the goal is to prevent Chinese firms from using American technology to develop their own advanced semiconductor capabilities, which poses a risk not only to the U.S. but also to allied nations.

Impact on global semiconductor market
In the wake of these developments, the stock prices of Japanese semiconductor equipment manufacturers rose significantly, as investors responded positively to the anticipated shift in supply chain dynamics. Companies like Advantest and Tokyo Electron saw increases of around 4.6%, while Applied Materials gained 4.9%. Conversely, the market reacted negatively to Chinese companies like Naura Technology Group and Piotech Inc., which experienced declines of 3% and 5.3%, respectively, following the announcement.
The newly implemented export controls could instigate a major shift in the semiconductor landscape, compelling Chinese firms to accelerate initiatives aimed at achieving technological self-sufficiency. Beijing has invested heavily in domestic semiconductor initiatives, seeking to reduce its reliance on foreign technology amidst increasing pressures from the U.S. The Chinese government has stated its determination to stabilize and fortify its advanced chip production capabilities.
Compounding the complexities of the situation, the U.S. has expanded the “foreign direct product” rule, which allows for more stringent controls over non-U.S. manufacturers that utilize American technology in their products. Companies based in Japan and the Netherlands, while typically exempt, may face indirect repercussions through the actions of their suppliers and partners that engage with the Chinese market.
Despite ongoing tensions, the global semiconductor industry remains vigilant.
