China has urged the United States to stop expanding restrictions on American investments in sensitive technologies linked to China, warning that the proposed measures could damage bilateral economic relations. The response followed a US Treasury Department announcement on October 22, 2026, proposing updates to the country’s Outbound Investment Security Program under new legislation designed to limit the transfer of capital and related expertise to foreign adversaries.
The proposed changes would broaden the scope of existing restrictions, adding biotechnology and expanding coverage of high-performance computing, supercomputing and hypersonic systems, alongside rules covering artificial intelligence and other strategic technologies. Beijing has described the proposal as discriminatory and said it reserves the right to take countermeasures. The US government, meanwhile, says the programme is intended to prevent American investment from supporting foreign military, intelligence, surveillance and cyber capabilities. The proposal remains subject to public consultation before final regulations take effect.
Key Takeaways
- China’s objection: Beijing has urged Washington to halt the proposed expansion of restrictions on US investments involving sensitive technologies.
- New technology sectors: The US proposal adds biotechnology and expands coverage of high-performance computing, supercomputing and hypersonic systems.
- Existing restrictions: Certain US investments involving Chinese semiconductor, quantum technology and AI businesses are already subject to restrictions or notification requirements.
- National security rationale: Washington says the rules aim to prevent US capital and associated expertise from supporting strategic capabilities of countries of concern.
- Potential retaliation: China’s commerce ministry has reserved the right to take countermeasures but has not specified what they would involve.
- Next step: The Treasury Department is accepting public comments until December 7, 2026, before issuing final implementing regulations.
What Did China Say About the US Proposal?
China’s Ministry of Commerce objected to Washington’s proposed changes on October 24, saying the expansion would intensify investment restrictions targeting China and undermine economic cooperation between the two countries.
According to Reuters, Beijing argued that the proposal ran counter to understandings reached by the two countries’ presidents, who had met twice in the preceding six months. China’s commerce ministry also warned that the measures could harm bilateral economic ties and said it reserved the right to respond.
The statement did not specify which countermeasures China might consider. Any response could depend on the final scope of the American rules and how they affect Chinese businesses, US investors and cross-border technology partnerships.
The dispute highlights a broader disagreement over how governments should regulate international investment in strategically important industries. Washington views certain capital flows as a potential channel for transferring technology and expertise. Beijing argues that expanding such restrictions risks interfering with normal commercial cooperation.
What Are the US Outbound Investment Restrictions?
The US Outbound Investment Security Program is designed to restrict or require notification of certain investments by US persons in covered foreign entities involved in sensitive technologies.
The programme was initially established through an executive order in August 2023. The Treasury Department issued implementing regulations in October 2024, which took effect on January 2, 2025.
The original framework focused on three main areas:
- Semiconductors and microelectronics
- Quantum information technologies
- Artificial intelligence
Depending on the technology, transaction and entity involved, certain investments may be prohibited while others require notification to the US Treasury Department.
The underlying concern is that investment can provide more than money. Investors may also contribute management expertise, commercial relationships, access to networks and other forms of assistance that help a company develop strategically important capabilities.
The programme is not a blanket prohibition on every investment involving China. Its application depends on the transaction, the parties, the technology and the relevant regulatory definitions.
What Changes Under the Proposed Expansion?
On October 22, the US Treasury Department published a proposed rule to implement the Comprehensive Outbound Investment National Security Act, known as the COINS Act, which Congress enacted as part of the fiscal year 2026 National Defense Authorization Act.
The proposal would update the existing programme and expand the categories of technologies subject to scrutiny.
| Technology sector | Proposed regulatory direction | Why it matters |
|---|---|---|
| Semiconductors and microelectronics | Updated technical definitions and coverage | These technologies underpin advanced computing and electronics |
| Artificial intelligence | Expanded regulatory framework, including advanced AI systems | AI can support commercial applications as well as military and intelligence capabilities |
| Quantum technologies | Updated programme requirements | Quantum systems have potential applications in computing, sensing and communications |
| High-performance computing and supercomputing | Expanded coverage | Advanced computing supports complex modelling and other strategic workloads |
| Hypersonic systems | Added coverage under the proposed framework | These systems have potential military applications |
| Biotechnology | Newly added sector | Certain biotechnology capabilities can have implications for national security and defence |

The proposal also addresses covered foreign persons, notification requirements, excepted transactions, compliance expectations and potential penalties. Its precise effect on any particular investment will depend on the final regulations and the circumstances of that transaction.
The inclusion of biotechnology is notable because the proposed framework reaches beyond the three sectors covered by the original programme. It reflects a wider US effort to assess how cross-border investment may support capabilities with both civilian and military applications.
Why Is Washington Expanding Investment Controls?
The US government says investment restrictions are intended to prevent American capital from supporting the development of strategic technologies that could threaten national security.
The Treasury Department argues that certain investments can help foreign companies expand their technical capabilities, strengthen research programmes and develop products with military, intelligence, surveillance or cyber applications.
The COINS Act provides a statutory framework for restrictions and notification requirements covering specified technologies and countries of concern. It also authorizes the Treasury Department to propose additional technology categories through a regulatory process.
The policy is part of a broader effort to manage national security risks arising from advanced technology competition. Other measures, including export controls and restrictions on access to certain technologies, address different channels through which capabilities can move across borders.
Investment controls are distinct because they focus on the provision of capital and associated benefits rather than simply the export of physical goods or software. They can therefore affect venture capital, private equity, joint ventures and other transactions when those activities fall within the rules.
What Could the Restrictions Mean for American Investors?
If the proposed rules are finalized, US investors and businesses may need to conduct more extensive due diligence before making investments involving covered foreign entities.
Companies could need to establish whether a prospective investment involves a restricted technology, whether the recipient is a covered foreign person and whether the transaction is prohibited or subject to notification.
This could affect investment decisions in areas such as advanced computing, AI research, biotechnology and other strategic industries. Firms may also need to review their compliance systems, investment documentation and processes for monitoring transactions through overseas subsidiaries.
However, the proposal does not mean that all US investment in China would become illegal. The framework distinguishes between covered transactions, prohibited activities, notifiable investments and transactions that may qualify for exceptions.
The Treasury Department has also said it is seeking feedback on the proposal before issuing final regulations. Investors should therefore distinguish between existing obligations and requirements that remain proposed.
Potential Consequences for China-US Business Relations
The disagreement creates uncertainty for companies operating across both markets. US investors may delay some transactions while they assess whether new restrictions could apply, while Chinese businesses may face additional scrutiny when seeking funding from American sources.
Restrictions on investment can influence more than the availability of capital. Cross-border investors may provide technical knowledge, business connections, strategic advice and access to international markets. Reducing these links could affect how some technology companies finance research, expand operations or form partnerships.
The effects will vary across industries. Businesses whose activities fall outside the covered technologies or qualify for exceptions may experience limited direct impact. Companies operating in regulated sectors could face higher compliance costs and greater uncertainty about future transactions.
China’s warning about possible countermeasures adds another variable for businesses to monitor. Until Beijing specifies its response and Washington finalizes the rule, the scale of any additional commercial disruption remains uncertain.
What Happens Next?
The Treasury Department is accepting public comments on the proposed rule until December 7, 2026. The department says it will consider stakeholder feedback before issuing final implementing regulations, which will establish the programme’s effective date.
Investors, technology companies and industry groups can use the consultation process to raise questions about the scope of covered transactions, technical definitions, reporting obligations and enforcement provisions.
The final rule may differ from the proposal after the government reviews those submissions. Companies should monitor official Treasury guidance rather than assume every proposed provision is already in force.
For China, the immediate issue is whether Washington modifies its approach following objections from Beijing and other stakeholders. For US investors, the priority is understanding how the new statutory framework could affect future investment decisions.
The Bigger Picture
The dispute reflects the increasing use of investment policy as a national security tool in competition over advanced technology. Governments are looking beyond exports and imports to examine how capital, expertise and commercial relationships can contribute to the development of sensitive capabilities.
For businesses, this creates a more complicated environment for international investment. Companies must increasingly assess not only commercial returns but also the regulatory status of technologies, counterparties and cross-border transactions. The final impact of the US proposal will depend on how broadly the rules are defined, how exceptions are applied and whether China responds with additional measures.
FAQs
1. Why is China asking the US to halt outbound investment restrictions?
China’s commerce ministry argues that the proposed expansion unfairly increases restrictions on investments involving China and could harm bilateral economic relations. Beijing has also said the proposal conflicts with understandings reached between the countries’ leaders.
