Summary of Key Points
The United States has implemented export control policies targeting China's chip and artificial intelligence (AI) sectors for several years. These measures have evolved, from restrictions on EUV lithography machines during the Trump administration to the Biden administration's "small courtyard, high wall" strategy, which includes the use of entity lists and the Foreign Direct Product Rule (FDPR). However, the actual outcomes have been less than satisfactory. On one hand, the U.S. has faced issues with poor enforcement due to a lack of bureaucratic personnel and policy inconsistency. On the other hand, China has promoted independent innovation through industrial policies (such as Huawei's LogicFolding technology) and initial methods like smuggling and re-exporting goods. More significantly, the restrictions have caused U.S. companies to lose access to the Chinese market and reduce their R&D investments, while also forcing the Chinese tech industry to become more secretive, making it difficult for outsiders to assess its true capabilities. The international think tank IISS believes that the U.S. needs to re-evaluate the benefits and costs of these controls, as they may have backfired.
Detailed Analysis
1. U.S. Control Policies: From "Comprehensive Blockade" to "Targeted Strains," with Increasing Stringency
U.S. technology restrictions on China have been gradual and progressively tightened:
- Trump Administration: In 2019, the U.S. banned Dutch company ASML from selling EUV lithography machines to China, which are essential for manufacturing advanced chips, and added Huawei and other companies to the entity list, preventing them from purchasing U.S. technology.
- Biden Administration: The "small courtyard, high wall" strategy was introduced, focusing on the most critical technologies for national security (such as advanced chips and AI) and implementing stricter policies, including the FDPR. This rule applies even to products manufactured by foreign companies if they use U.S.-owned hardware, software, or technology.
- Second Trump Administration: Control measures became more opportunistic; for example, in 2025, when China threatened to restrict rare earth exports (essential for many U.S. industries), the U.S. temporarily suspended the related entity rules, indicating that policies can shift based on geopolitical considerations.
2. Poor Enforcement of Control Policies: Insufficient Personnel and Inefficiency
Even the strictest policies are ineffective if not properly enforced:
- Bureaucratic Challenges: The Bureau of Industry and Security (BIS), responsible for export controls, has faced staffing and funding shortages. A 2024 Senate report highlighted difficulties in regulating Russian semiconductors, let alone a large market like China.
- Policy Inconsistency: Policy changes, such as the suspension of the related entity rules in 2025 to appease China's rare earth concerns, have created loopholes for Chinese companies.
- Companies Finding Loopholes: Despite increased efforts to crack down on smuggling, Southeast Asia has become a key route for re-exporting goods, with chips first sold to neighboring countries and then transferred to China.
3. China's Response: From "Bypassing Restrictions" to "Developing Independently," with Independent Innovation as the Mainstream
China has actively responded to the restrictions:
- Initial Measures: China stockpiled chips, resorted to smuggling, and used third-party re-export channels. However, these tactics were temporary, as the U.S. later negotiated agreements with Southeast Asian countries to shut down these loopholes.
- Long-Term Strategies: The Chinese government has focused on industrial policies and supported breakthroughs in key technologies, such as Huawei's LogicFolding technology that allows the production of advanced chips without EUV lithography machines. Chinese AI company Z.ai quickly released a cheaper alternative model after Anthropic's restrictions. NVIDIA CEO Jensen Huang suggested that China's chip development is only a few nanoseconds behind the U.S.
4. The Negative Consequences of Controls: Disadvantages for U.S. Companies and Increased Chinese Secrecy
The restrictions have had unintended consequences for the U.S.:
- Market Losses for U.S. Companies: Prohibitions on selling products to China result in significant revenue losses for U.S. firms, such as NVIDIA, which misses out on potential profits that could be invested in R&D.
- Increased Chinese Secrecy: Chinese companies are becoming more secretive, making it harder for the U.S. to assess their technological capabilities.
- Push for Domestic Development: The restrictions have forced China to develop its own technology ecosystems, accelerating its independent innovation process.
5. Reconsidering the Effectiveness of Controls
The IISS report suggests that U.S. control policies may be counterproductive:
- Failing to Halt China's Progress: China's advancements in chip and AI have outpaced expectations, and the restrictions have not hindered its development.
- Higher Costs for the U.S.: U.S. companies face market losses and slowed R&D, while China has become more self-reliant.
- Need for Re-Evaluation: The U.S. must weigh the benefits of these controls against the costs, including potential losses to its own industries and the risks of China's increased independence.
Conclusion
U.S. efforts to restrict Chinese technology have ultimately led to increased Chinese innovation and have caused significant setbacks for U.S. companies. This highlights that technological competition is not about simple blockades but about who can innovate more quickly. For the U.S., focusing on its own R&D and enforcement is more effective than trying to cut off competitors. For China, independent innovation is the key to breaking through foreign restrictions. The future of technological competition will likely be more complex, but the ultimate goal remains control of core technologies.
