In a significant move to safeguard national security and maintain technological leadership, the U.S. Commerce Department has introduced stringent export controls targeting advanced chip-design software, chemicals, and related technology equipment destined for China. Announced on May 29, 2025, these restrictions mark a continuation of the United States’ efforts to curb China’s access to cutting-edge technologies that could bolster its military and artificial intelligence (AI) capabilities. This decision, part of a broader strategy to protect U.S. interests, has sparked global attention and raised questions about its impact on the semiconductor industry, international trade, and U.S.-China relations.
The U.S. Commerce Department, through its Bureau of Industry and Security (BIS), has been tightening export controls on advanced technology since October 2022, when it first introduced measures to limit China’s ability to acquire high-performance semiconductors, supercomputers, and related manufacturing equipment. These actions stem from concerns that China’s advancements in AI, supercomputing, and military modernization could pose a threat to U.S. national security. The latest restrictions, effective immediately, target electronic design automation (EDA) software, critical chemicals used in semiconductor production, and specific technology equipment.
According to reports, major U.S. and allied companies, including Cadence Design Systems, Synopsys, and Siemens EDA, have been instructed to halt sales of their chip-design software to Chinese customers without obtaining an export license. These companies collectively dominate approximately 80% of China’s chip design market, making this a pivotal move in the U.S.’s technology containment strategy. Additionally, the restrictions extend to chemicals essential for semiconductor manufacturing and other strategic goods, such as jet engine technology, further tightening the screws on China’s tech ambitions.
The U.S. government views advanced semiconductors and related technologies as critical to maintaining a strategic edge in fields like AI, quantum computing, and military applications. Assistant Secretary of Commerce for Export Administration Thea D. Rozman Kendler previously stated that China’s efforts to become a global leader in AI by 2030, coupled with its use of advanced computing for surveillance and military purposes, necessitated these controls. The 2021 National Security Commission on Artificial Intelligence warned that if China surpasses the U.S. in chip technology, it could gain a military advantage across various domains, including autonomous weapons and cyber capabilities.
The new rules specifically target:
These measures build on previous restrictions, such as the October 2022 rules that added advanced chips and manufacturing equipment to the Commerce Control List (CCL) and imposed licensing requirements for exports to China. The latest controls also expand the Foreign Direct Product (FDP) rules, affecting foreign-made items that rely on U.S. technology or software, and add over 140 Chinese entities to the BIS Entity List, including major players like Huawei, SMIC, and their affiliates.
The semiconductor industry is a cornerstone of the global economy, powering everything from smartphones to medical devices and defense systems. China, which accounts for roughly 50% of global chip sales by revenue, is a critical market for U.S. and allied companies. The new restrictions are likely to have significant repercussions for both American firms and their Chinese counterparts.
For U.S. companies like Cadence, Synopsys, and Lam Research, the immediate impact may be a loss of revenue from the Chinese market. Posts on X indicate that these firms have been ordered to suspend sales, which could disrupt supply chains and affect their bottom lines. However, the U.S. has attempted to mitigate this by exempting allies like Japan, the Netherlands, and South Korea from certain restrictions, recognizing their role in producing advanced chipmaking equipment. This carve-out aims to maintain cooperation with key partners while targeting China’s indigenous production capabilities.
For Chinese companies, the restrictions pose a significant challenge to their “independent and controllable” campaign, which seeks to achieve self-sufficiency in semiconductor production. Companies like SMIC and Huawei have made strides in developing advanced chips, such as 7nm and 5nm processors, despite earlier controls. However, the latest rules, particularly those targeting EDA software and chemicals, could slow their progress by limiting access to critical tools and materials. For instance, SMIC’s new $7.6 billion plant has faced delays due to difficulties in securing equipment, a situation likely to worsen under the new restrictions.
China’s Ministry of Commerce has strongly criticized the U.S. measures, describing them as “economic coercion” and “non-market practices.” In response to earlier controls, China imposed its own export restrictions on critical minerals used in semiconductor and defense industries, signaling a tit-for-tat approach. On May 19, 2025, China accused the U.S. of undermining global trade consensus and pledged to take further action if the restrictions persist. This escalation raises the risk of a broader trade conflict, potentially disrupting global supply chains and increasing costs for consumers.
Despite these challenges, some experts believe China’s technological progress will not be entirely halted. Zhou Linwen, chief science editor at The China Academy, argued that Chinese engineers and scientists are capable of developing their own solutions, as evidenced by Huawei’s launch of a 5nm chip in 2023. However, achieving self-sufficiency in advanced chip design and production remains a complex and costly endeavor, and the new restrictions could delay China’s ambitions by several years.
The U.S. export controls are part of a broader strategy to counter China’s Military-Civil Fusion doctrine, which integrates civilian technology advancements with military objectives. The Biden administration, and now the Trump administration, have adopted a “small yard, high fence” approach, focusing on protecting a select group of critical technologies rather than imposing blanket restrictions. This strategy is evident in the targeted nature of the controls, which focus on advanced-node ICs and high-performance computing while allowing exports of legacy chips for consumer applications.
Looking ahead, the Trump administration has signaled a continuation of aggressive export controls, with Under Secretary of Commerce for Industry and Security Jeffrey I. Kessler emphasizing the need to prevent U.S. technologies from being used in Chinese military applications like hypersonic weapons and quantum computing. The addition of 140 Chinese entities to the Entity List in December 2024, including Huawei-connected fabs and research centers, underscores this commitment.
However, the effectiveness of these controls remains uncertain. While they have disrupted China’s semiconductor ecosystem, they have also spurred Beijing to double down on its self-reliance efforts. Chinese firms have resorted to stockpiling equipment and using shell companies to acquire restricted technologies, as seen in Huawei’s reported smuggling of 2 million chiplets from TSMC. These workarounds highlight the challenges of enforcing export controls in a globalized industry where chips and software can be easily concealed or rerouted.
The U.S. Commerce Department’s latest export restrictions on advanced chip-design software, chemicals, and technology equipment represent a bold step to protect national security and maintain technological supremacy. By targeting critical tools and materials, the U.S. aims to slow China’s progress in AI, supercomputing, and military modernization. However, the measures come with trade-offs, including potential revenue losses for U.S. companies and the risk of retaliatory actions from China. As the U.S.-China tech rivalry intensifies, the global semiconductor industry faces an uncertain future, with implications for innovation, trade, and geopolitical stability.
