US Treasury Proposes Expanded Rule to Crack Down on High-Tech Investments in China and Adversaries

US Treasury Expands Restrictions on High-Tech Investments

The US Treasury Department has proposed a comprehensive rule to crack down on high-tech investments flowing to China, Russia, North Korea, and other countries of concern1

1

. The proposal marks a significant expansion of the Outbound Investment Security Program, targeting American capital that could accelerate adversarial military capabilities in critical technology sectors2

2

. Treasury Secretary Scott Bessent emphasized that these regulations aim to prevent adversaries from using U.S. investment to develop technologies that threaten national security4

.

The new rule would apply restrictions on high-tech investments exceeding $50,000, while excluding many financial investments such as stock purchases3

3

. This threshold ensures focused oversight on substantial capital flows that could meaningfully enhance technological development in adversarial nations.

Expanded Technology Coverage Under New Proposal

The proposed rule significantly broadens the scope of restricted technologies beyond previous frameworks. Restrictions now cover artificial intelligence—referred to as "superintelligence" or SI in Treasury documentation—alongside supercomputing, hypersonic systems capable of traveling at five times the speed of sound, and biotechnology1

1

. This expansion reflects growing concerns about how American capital might accelerate military-relevant capabilities in adversarial nations.

Craig Singleton, senior fellow at the Foundation for Defense of Democracies, noted that the screening of outbound investments "recognizes that capital can accelerate military-relevant capabilities just as surely as technology transfer can"5

. The proposal sends a clear signal to markets that Washington is actively tracking where U.S. capital flows and what capabilities it helps build.

Evolution from 2023 Executive Order to Legislative Action

The current proposal implements the Comprehensive Outbound Investment National Security Act passed by Congress in December 20252

2

. This legislative framework codifies and expands initiatives that began with a 2023 executive order signed by then-President Joe Biden, which initially restricted outbound U.S. investments in sectors such as semiconductors, quantum computing, and artificial intelligence going into China1

.

The December 2025 law expanded the program to target additional technologies and foreign countries, including Cuba, Iran, North Korea, and Russia3

3

. Notably, Russia's inclusion comes days after President Donald Trump waived sanctions on Russia following a diesel deal with President Vladimir Putin, highlighting the complex geopolitical dynamics surrounding economic security measures.

Implementation Process and Compliance Requirements

Jason Chipman, a former Justice Department lawyer specializing in cybersecurity and investment rules at WilmerHale, stated that the new rule "will require more substantial compliance programs to manage risk"1

1

. The Treasury will collect public comments on the proposal before issuing a final rule, indicating a measured approach to implementation.

Ryan Majerus, former U.S. trade official and partner at King & Spalding law firm, characterized the proposal as "just the first step in a fairly long process to get to changes which presumably will be more enforcement-minded, to put more teeth behind the outbound investment program"5

5

. This suggests that businesses should prepare for increasingly rigorous oversight of their international investment activities.

U.S.-China Tech Rivalry Intensifies

The proposal emerges against the backdrop of an intensifying U.S.-China tech rivalry that has defined relations between the world's two largest economies since Trump's first term3

3

. Both nations have restricted exports of sensitive technology and critical products—China's rare earth minerals and America's advanced computer chips—while imposing tariffs on each other's goods. Although Trump and Chinese President Xi Jinping agreed to ease tensions through dialogue, extending a temporary truce into January, enforcement actions continue.

In July, the Treasury Department issued a $200,000 fine against a U.S.-based company for failing to report a $92,500 investment in a Chinese artificial intelligence and robotics company1

1

. This enforcement action demonstrates the government's commitment to monitoring compliance with existing regulations.

International Response and Market Implications

China has responded critically to the proposal. Chinese Foreign Ministry spokesperson Mao Ning stated that "overstretching the concept of national security, taking discriminatory measures against specific countries, and artificially restricting trade, economic and investment activities serve no one's interests"2

2

. The Chinese Ministry of Commerce accused the U.S. of attempting to suppress China under "the guise of national security," warning that China will monitor developments closely and take necessary measures to defend its interests4

.

The curbs on high-tech investments signal Washington's determination to maintain technological leadership while preventing capital from strengthening adversarial military capabilities. As the regulatory framework evolves, companies engaged in international technology investments must navigate increasingly complex compliance requirements while balancing economic opportunities against national security considerations.
