A University of Michigan researcher and her boyfriend have been implicated in an alarming attempt to smuggle a hazardous biological pathogen capable of damaging crops into the United States. This revelation comes as the U.S. Department of Justice announced charges against Yunqing Jian and Zunyong Liu, both Chinese nationals, for conspiracy and smuggling.

According to authorities, Jian, a postdoctoral research fellow at the University of Michigan, and Liu, a researcher at Zhejiang University in China, conspired to import Fusarium graminearum, described as a "noxious fungus," into the U.S. The pathogen is known to cause head blight disease in various crops, including wheat, barley, and corn, significantly affecting their quality and yield. Additionally, the toxins produced by the fungus pose serious health risks, such as vomiting and liver damage.

The charges were brought to light when Liu attempted to bring samples of the toxic fungus from China to the U.S. in July 2024 during a visit to Jian. Upon arrival at Detroit Metropolitan Airport, Liu was stopped by Customs and Border Protection officers, who discovered four plastic bags filled with different strains of the fungus concealed inside crumpled tissues in his backpack. Initially, Liu claimed ignorance about the presence of the samples but later admitted to hiding them, knowing there were import restrictions.

Further investigations by the FBI unearthed electronic communications indicating that Jian and Liu had previously discussed the importation of biological materials for academic research and may have collaborated on smuggling seeds into the U.S. in August 2022. This led to Liu's deportation to China and Jian's arrest, followed by her court appearance this week.

In response to the incident, the University of Michigan issued a statement condemning any activities that could harm public safety or national security. They clarified that no Chinese government funding was received for the research carried out by the individuals involved and assured full cooperation with federal authorities.

Meanwhile, the FBI's investigation revealed that Jian had expressed loyalty to the Chinese Communist Party (CCP) and had prior funding from the Chinese government for similar research in China. This was supported by documents found on Jian's laptop indicating her membership in the CCP.

During a press briefing, China's Foreign Ministry expressed its commitment to ensuring its citizens comply with local laws and protect their legitimate rights abroad. This case follows recent U.S. measures to revoke visas for Chinese students linked to the CCP or those studying in critical fields, attributing these actions to concerns over exploitation of American academic institutions by the CCP.

The incident has heightened tensions and uncertainties for Chinese students and researchers in the U.S., highlighting the complexities of international academic and security dynamics.
