FBI Director Kash Patel sharply criticized Serbia during a U.S. Senate hearing on Friday, May 15, 2026, using the Balkan nation as a primary negative example of international judicial cooperation.
Patel’s comments came during a intense line of questioning by Senator Chris Coons regarding the taxpayer costs and justification for the FBI Director’s trip to the Winter Olympics in Milan, Italy, earlier this year. In defending the utility of his European visit, Patel disclosed that the trip served as a operational hub for high-stakes international law enforcement.
The Milan Operation vs. The “Serbia Precedent”
During his exchange with Senator Coons, Patel revealed that while in Italy, U.S. officials successfully coordinated an operation leading to the extradition of Chinese cyber-operative Xu Zewei to the United States.
Patel contrasted this success directly with past frustrations in Belgrade, alleging that Serbia has repeatedly allowed high-value targets sought by Washington to be diverted back to Beijing.
“While we were there, we managed to arrange for that individual to be extradited to America instead of being sent back to China, as has frequently happened in countries like Serbia,” Patel testified before the Senate committee.
Context: The Escape of Cui Guanghai and John Miller
Patel’s remarks directly reference a major diplomatic and security embarrassment for Belgrade involving Chinese national Cui Guanghai and British national John Miller.
The two men were arrested in Serbia on an international warrant issued by the United States. However, in September 2025, the Higher Court in Belgrade confirmed that both suspects managed to remove their electronic tracking ankles, escape house arrest, and vanish. Investigative reports by BIRN later revealed that the duo successfully fled Belgrade for Beijing aboard a private flight.
The U.S. Charges Against the Fugitives:
- Transnational Repression: The U.S. Department of Justice alleged that Cui and Miller organized a systematic campaign of intimidation against a U.S. citizen who was a vocal critic of Chinese President Xi Jinping.
- APEC Sabotage: They were accused of attempting to suppress protests against President Xi during the 2023 APEC Summit in San Francisco, including trying to block the display of anti-regime artwork.
- Financial Incentives: FBI investigators discovered the suspects paid tens of thousands of dollars to individuals within the U.S. to forcefully silence critics of the Chinese government.
- Military Smuggling: Beyond espionage and harassment, both individuals faced separate federal indictments for attempting to illegally smuggle sensitive U.S. military technology into China.
A Breach of Treaty Obligations
The incident remains a highly sensitive issue for Washington-Belgrade relations. In 2019, Serbia and the United States ratified a comprehensive extradition treaty that permits the handover of suspects regardless of nationality.
Patel’s public rebuke before the U.S. Senate underscores growing frustration within the American intelligence community over Belgrade’s geopolitical balancing act, suggesting that Serbia prioritized its strategic partnership with Beijing over its legally binding extradition treaties with the United States.
