U.S. Treasury Proposes Rules to Restrict AI Investments in China
The U.S. Department of the Treasury has released a notice of proposed rulemaking to restrict American investments in Chinese companies developing artificial intelligence, semiconductors, and quantum computing. These rules implement an executive order signed by President Joe Biden in August 2023, which aims to prevent U.S. capital and expertise from supporting technologies that could enhance China’s military and intelligence capabilities. The proposed regulations require U.S. persons and entities to notify the Treasury Department of certain transactions or prohibit them entirely, depending on the specific technology sector.
Scope of the Proposed Investment Restrictions
The Treasury Department’s proposal focuses on “countries of concern,” specifically China, Hong Kong, and Macau. The rules target three primary areas of concern: artificial intelligence, semiconductors, and quantum information technologies. Under these provisions, U.S. investors would be prohibited from participating in transactions involving:

- Artificial Intelligence: Systems designed for military applications, cybersecurity, or surveillance, as well as AI models requiring significant computing power to train.
- Semiconductors: Technologies involved in the design, fabrication, or packaging of advanced integrated circuits.
- Quantum Information: Technologies related to quantum computers, sensors, and secure communication systems.
According to the Treasury, the goal is to create a “narrowly tailored” program that prevents the transfer of “know-how” and capital that could assist in the development of technologies critical to military modernization. The rules apply to private equity, venture capital, and joint ventures, among other investment vehicles.
Compliance and Reporting Requirements
The proposed framework distinguishes between prohibited transactions and those that merely require disclosure. Prohibited transactions involve specific high-risk technologies where the risk to U.S. national security is deemed too great. Conversely, notification-only requirements apply to transactions in technology sectors where the risks are lower but still warrant government oversight.

The Office of Investment Security within the Treasury Department will manage the program. U.S. persons who fail to comply with these rules could face civil and criminal penalties. The rulemaking process includes a public comment period, allowing industry stakeholders and legal experts to provide feedback before the regulations are finalized.
Comparing U.S. Export Controls and Investment Restrictions
These investment restrictions complement existing U.S. efforts to limit China’s technological advancement, most notably the export controls managed by the Department of Commerce. While export controls restrict the physical sale of hardware and software to Chinese firms, the Treasury’s new rules address the flow of money and intellectual guidance.

| Mechanism | Primary Focus | Agency |
|---|---|---|
| Export Controls | Physical goods, software, and technology transfers | Department of Commerce |
| Investment Restrictions | Capital flows, venture funding, and advisory services | Department of the Treasury |
Looking Ahead
The Treasury Department is currently reviewing comments submitted by industry groups and the public. Once the comment period concludes, the agency will finalize the regulations. Market analysts expect the final rules to clarify the definitions of “AI systems” and “advanced integrated circuits” to ensure that general-purpose commercial software and consumer electronics are not inadvertently caught in the scope of the restrictions.
As the U.S. seeks to balance economic engagement with national security, these regulations represent a significant shift toward increased scrutiny of cross-border investment. The outcome will likely influence how venture capital firms and multinational corporations structure their portfolios involving Chinese entities for the foreseeable future.
