US federal prosecutions of individuals accused of acting as undeclared agents of China have surged, with the DOJ bringing 52+ cases under the Foreign Agents Registration Act (FARA) and Section 951 since 2018—a 300% increase from the previous six-year period. These cases often involve allegations of espionage, transnational repression, or covert influence operations, carrying penalties of up to 10 years imprisonment and $250,000 fines. For defendants, navigating these charges requires an understanding of the legal frameworks, DOJ tactics, and emerging defense strategies. Here’s a comprehensive overview of the landscape in 2025.
I. Legal Frameworks: FARA vs. Section 951
1. Foreign Agents Registration Act (FARA)
– Purpose: Requires individuals engaged in political activities (e.g., lobbying, public relations) on behalf of foreign governments or entities to register with the DOJ. Enacted in 1938 to counter foreign propaganda.
– Key Aspects:
– Focuses on transparency rather than criminalizing influence itself.
– Exemptions exist for commercial activities, diplomacy, and journalism, though these are narrowly interpreted.
– Enforcement Trends: DOJ has shifted from rare prosecutions to aggressive enforcement, particularly since 2019.
2. Section 951 (U.S. Code Title 18)
– Purpose: Criminalizes acting as an agent of a foreign government without notification to the Attorney General. Unlike FARA, it explicitly targets clandestine activities.
– Scope: Often used in cases involving espionage, intelligence gathering, or coercion (e.g., “Operation Fox Hunt”).
– Penalties: Up to 10 years imprisonment per count.
Critical Difference: FARA is a disclosure law (failure to register is the offense), while Section 951 criminalizes the act of being an unregistered agent.
II. 2025 Case Trends: From Espionage to Transnational Repression
1. Espionage and Intellectual Property Theft
– Cases:
– Xu Yanjun (2021): A Chinese Ministry of State Security (MSS) officer convicted of stealing GE Aviation engine technology.
– Yuance Chen & Liren Lai (2025): Accused of recruiting U.S. Navy personnel and facilitating cash dead drops for MSS.
– Tactics: Targeting cutting-edge tech (e.g., aviation, AI) via recruitment of experts and dead drops.
2. Transnational Repression (“Operation Fox Hunt”)
– Cases:
– Quanzhong An (2025): A New York businessman sentenced to 20 months for coercing a Chinese expatriate to return to China.
– Shujun Wang (2024): A former professor accused of monitoring U.S.-based dissidents for MSS.
– Methods: Harassment, surveillance, and threats against critics of the Chinese government.
3. Covert Influence Operations
– Cases:
– Yaoning “Mike” Sun (2024): Charged with influencing Southern California city council elections on behalf of China.
– Sue Mi Terry (2024): A former CIA official accused of lobbying for South Korea’s intelligence service without registration.
– Goals: Shaping policy related to Taiwan, Tibet, or U.S.-China relations.
III. Defense Strategies: Challenging DOJ’s Theories
1. Constitutional Challenges
– First Amendment Arguments: Claiming activities constitute protected speech or advocacy (e.g., pro-Beijing lobbying).
– Selective Enforcement: Arguing DOJ targets Chinese-Americans or political critics.
2. Challenging “Agency” Definitions
– Lack of Direction or Control: Proving actions were independent, not directed by a foreign government.
– Example: Litang Liang (2025) acquitted after arguing his advocacy (e.g., counter-protests) was personal, not MSS-directed.
3. Procedural Defenses
– Evidence Issues: Contesting illegally obtained evidence or insufficient proof of foreign government ties.
– Jurisdictional Arguments: Questioning whether alleged actions occurred within U.S. jurisdiction.
4. Negotiated Resolutions
– Plea Deals: Cooperating with DOJ to reduce charges (e.g., Maria Butina’s 2018 case resulted in a guilty plea and deportation).
– Deferred Prosecution: Corporations or individuals complying with DOJ’s voluntary self-disclosure programs.
IV. 2025 DOJ Enforcement Tactics
Tactic Description Case Example
Undercover Operations Using double agents or sting operations to gather evidence Xu Yanjun (FBI posed as a recruit)
Financial Surveillance Tracking illicit payments or money laundering linked to foreign governments Yuance Chen & Liren Lai (dead drops)
Cyber Evidence Using digital records (emails, messages) to prove agency relationships Shujun Wang (communications with MSS)
Witness Cooperation Leveraging testimony from co-defectors or victims Quanzhong An (testimony from coerced expatriate)
V. Critical Considerations for Defendants
1. DOJ’s Broad Interpretation of “Agent”
– Courts often defer to DOJ’s expansive views of “direction or control,” even for non-traditional activities (e.g., lobbying, academic exchanges).
– Risk Area: Commercial activities may still trigger liability if tied to foreign government interests.
2. Geopolitical Bias
– Cases involving China face heightened scrutiny; acquittal rates are lower than for allies (e.g., South Korea).
– Strategy: Venue selection (e.g., filing motions in districts with diverse juries) may reduce bias.
3. Collateral Consequences
– Deportation: Non-citizens face removal even after minor sentences (e.g., Ming Xi Zhang).
– Asset Forfeiture: Courts may seize properties or funds linked to alleged crimes.
VI. 2025 Trends and Future Outlook
1. Increased Corporate Enforcement
– DOJ’s National Security Division now prioritizes cases against corporations for FARA violations, especially in tech and logistics sectors.
– Compliance Tip: Implement internal FARA/Section 951 audits for employees engaged in foreign partnerships.
2. Focus on “Transnational Repression”
– New task forces target coercion of dissidents (e.g., Tibetans, Uyghurs, Hong Kong activists).
– Defense Challenge: Distinguishing between legitimate advocacy and illegal harassment.
3. Technological Sophistication
– DOJ uses AI to analyze communication patterns and financial transactions.
– Countermeasure: Encrypted communications and legal privilege assertions.
4. Political Dimensions
– Cases may be influenced by U.S.-China tensions; high-profile arrests often coincide with diplomatic disputes.

Conclusion: Strategic Recommendations for Defendants
1. Early Legal Intervention
– Retain counsel specializing in national security law before DOJ contacts occur.
– Proactive Step: Conduct a FARA/Section 951 compliance review for any foreign-linked activities.
2. Evidence Management
– Preserve exculpatory evidence (e.g., emails showing independent decision-making).
– Challenge DOJ’s digital evidence through forensic experts.
3. Public Relations Strategy
– Counter DOJ narratives via m
