Chinese companies investing in the United States must navigate the Committee on Foreign Investment in the United States (CFIUS) review process, which evaluates foreign acquisitions for national security concerns. The Foreign Investment Risk Review Modernization Act of 2018 (FIRRMA) significantly expanded CFIUS jurisdiction.

CFIUS Review for Chinese Investors

Scope of CFIUS Jurisdiction

CFIUS reviews transactions that could result in foreign control of US businesses, as well as certain non-controlling investments in technology, infrastructure, and data companies. Real estate transactions near sensitive US government facilities also fall within scope. Mandatory declarations are required for certain technology sector investments where the foreign investor obtains board membership or access to material non-public technical information.

Early engagement with CFIUS counsel is essential for Chinese investors. Well-prepared filings with appropriate mitigation strategies produce more predictable outcomes.

The Review Timeline

The CFIUS process begins with a voluntary notice or mandatory declaration. The initial 45-day review period may be followed by a 45-day investigation. Parties may withdraw and refile to address concerns. The total timeline typically ranges from three to six months for straightforward cases and longer for complex transactions.

Mitigation Agreements

When CFIUS identifies national security concerns, parties may negotiate mitigation agreements addressing governance, data access, supply chain security, and other risk factors. These agreements typically include corporate governance requirements, and their terms must be carefully structured to preserve the commercial value of the transaction.

Strategic Considerations

Chinese investors should engage CFIUS counsel early in deal planning. Transaction structure, target sector, and acquirer profile all influence CFIUS risk. Factor CFIUS timeline into transaction agreements with appropriate risk allocation provisions.

Mandatory Declarations vs. Voluntary Notices

FIRRMA introduced mandatory declarations for certain transactions involving US businesses producing, designing, testing, or manufacturing critical technologies. Short-form declarations trigger a 30-day CFIUS review but do not carry the same presumption of approval as a full notice. When in doubt, foreign investors should file a full voluntary notice, which affords the parties legal certainty once the process concludes without action or with a clearance letter. Voluntary notices initiate a 45-day review followed by a potential 45-day investigation period.

Penalty Exposure for CFIUS Non-Compliance

Failure to file a mandatory declaration or making material misstatements to CFIUS can result in civil penalties plus potential unwind of the transaction. Recent enforcement actions demonstrate that CFIUS actively monitors transactions for compliance. Chinese investors should implement robust CFIUS compliance procedures, including pre-transaction screening, legal holds on relevant documents, and coordination with US regulatory counsel throughout the deal process.

Sector-Specific Considerations

Technology transactions face particular CFIUS scrutiny. The Critical Technology list, maintained by the interagency Process for Assessing National Security Significance, covers advanced materials, AI, biotechnology, semiconductors, and quantum computing among others. Real estate transactions within 100 miles of sensitive US military installations also fall within CFIUS jurisdiction, requiring filings for acquisitions of land or property rights near such facilities.

Mitigation Agreement Structuring

When CFIUS identifies risks, mitigation agreements typically include governance provisions such as the establishment of a Security Committee with US national security-cleared directors, restrictions on data access and transfer, supply chain security requirements, and reporting obligations. Chinese investors should involve CFIUS counsel early to structure mitigation packages that address government concerns while preserving the commercial value of the transaction.

Deal Timeline Integration

CFIUS considerations should factor into transaction planning from the outset. Chinese investors should include CFIUS risk allocation provisions in letters of intent and acquisition agreements, including reverse termination fees for CFIUS-denied transactions and extended closing periods to accommodate CFIUS review timelines.

Critical Technology Sectors Under CFIUS Review

The CFIUS critical technology list covers 14 categories including advanced materials, AI, biotechnology, microelectronics, quantum computing, robotics, and semiconductors. Transactions involving Chinese investors and US companies developing these technologies face enhanced scrutiny. The Export Control Reform Act and ITAR intersect with CFIUS review as technology exports to Chinese entities may require separate licenses from the Bureau of Industry and Security.

Real Estate Transactions Near Sensitive Facilities

FIRRMA extended CFIUS jurisdiction to real estate transactions within 100 miles of US military installations. Chinese entities acquiring or leasing property near these sites must file CFIUS declarations. The Department of Defense maintains a map of covered facilities updated periodically.

Exemptions and Exceptions

Certain transactions are exempt including passive investments in publicly traded securities that do not confer board membership, minority investments in non-critical businesses, and internal reorganisations. Chinese state-owned enterprises face particular scrutiny with CFIUS examining whether the investor is controlled by the Chinese government.

Mitigation Agreement Best Practices

CFIUS mitigation agreements typically include governance provisions requiring US national security-cleared directors, restrictions on data access and technology transfer, supply chain security requirements, periodic compliance reporting, and audit rights. Chinese investors should negotiate mitigation packages that address government concerns while preserving transaction value. The CFIUS monitoring and enforcement process includes annual compliance reviews and the potential for renegotiation if circumstances change.

Planning for CFIUS-Contingent Deal Terms

Chinese investors should include CFIUS risk allocation in acquisition agreements from the outset. Common provisions include reverse termination fees for CFIUS-denied transactions typically 3-6% of enterprise value, extended outside closing dates to accommodate CFIUS review timelines, best efforts covenants for obtaining CFIUS clearance, and defined parameters for acceptable mitigation agreement terms.

Practical CFIUS Filing Preparation

Preparing a CFIUS filing requires gathering extensive information about the transaction structure, the foreign investor's ownership and governance, the U.S. target business's products and services, and the potential national security implications. The filing includes transaction agreements, organisational charts, business plans, and descriptions of the foreign investor's relationship with foreign governments. Chinese investors should prepare this documentation well in advance of the planned filing date and engage experienced CFIUS counsel to review the submission for completeness and accuracy before filing. Material omissions or misstatements can result in penalties and jeopardise the clearance outcome.

Managing CFIUS Risk Throughout the Transaction

Managing CFIUS risk requires a strategic approach from the earliest stages of transaction planning. Chinese investors should conduct preliminary CFIUS risk assessments during target screening, structure transactions with CFIUS considerations in mind from the outset, prepare comprehensive filing documentation, and develop mitigation strategies. Engaging CFIUS counsel early in the process and factoring CFIUS timeline into transaction agreements with appropriate risk allocation provisions are essential practices for successful CFIUS outcomes.

CFIUS Process by Transaction Type

The CFIUS process varies by transaction type. Mandatory declarations apply for certain critical technology investments where the foreign investor gains board membership, access to material technical information, or membership rights other than through voting shares. Real estate transactions near sensitive US facilities require mandatory filing. Voluntary notices provide legal certainty through a clearance letter. Notice filings require comprehensive transaction documentation, business plans, and detailed information about the foreign investor's ownership structure and government relationships. The process concludes with a clearance letter, a notice of mitigation agreement negotiation, an order blocking or unwinding the transaction, or referral to the President for decision in extraordinary cases.

Recent Trends in CFIUS Enforcement

CFIUS enforcement has increased substantially in recent years with larger penalty amounts and more aggressive monitoring of compliance with mitigation agreements. The Treasury Department has hired additional staff and developed specialised expertise in technology sectors relevant to Chinese investment. Chinese investors should expect thorough review of transactions involving AI, semiconductors, biotechnology, and quantum computing. Early engagement with CFIUS through the non-binding pre-filing consultation process helps identify potential issues before formal filing and reduces review timelines.

Legal Framework and Recent Developments

The Foreign Investment Risk Review Modernization Act of 2018 transformed CFIUS from a voluntary review system to one with mandatory filing requirements for certain transactions covering critical technologies, critical infrastructure, and sensitive personal data of US citizens. Recent regulatory changes have expanded mandatory filing requirements and increased penalties for non-compliance. Chinese investors should stay informed about regulatory developments and adjust their CFIUS compliance strategies accordingly. Regular consultation with experienced CFIUS counsel is essential for navigating this evolving regulatory landscape and ensuring timely and complete filings that maximise the likelihood of timely clearance.
