In a major national security development, FBI Director Kash Patel confirmed the arrest of two Chinese nationals for allegedly smuggling a dangerous biological pathogen, Fusarium graminearum, into the United States. The arrests were made in connection with a suspected agroterrorism plot tied to research activities at the University of Michigan.
According to Patel, the primary accused, Yunqing Jian, reportedly brought the highly infectious fungus into the U.S. to study its effects. Fusarium graminearum, also known as “head blight,” is a crop-destroying pathogen that affects wheat, maize, barley, and rice—leading to billions in global agricultural losses and posing health risks to humans and livestock.
The FBI revealed that Jian received research funding from the Chinese government and had allegedly expressed loyalty to the Chinese Communist Party (CCP). Her boyfriend, Zunyong Liu, also a researcher, was charged after admitting to smuggling the same fungus through Detroit Metropolitan Airport. Liu conducts similar research at a university in China.
Both face serious charges including conspiracy, smuggling biological agents, providing false statements, and visa fraud. The FBI, in coordination with U.S. Customs and Border Protection (CBP), carried out the arrests as part of a broader effort to safeguard national biosecurity.
Calling the incident a “stark warning,” Patel emphasized the growing threat of foreign operatives infiltrating American research institutions with intent to undermine U.S. infrastructure—including its food supply chain. “Justice will be done,” he assured in a post on X.
