Chinese Citizens Charged in U.S. for Smuggling Harmful Fungus, Sparking National Security Concerns
June 3, 2025
This incident follows another case involving a University of Michigan student, Haoxiang Gao, who fled to China after being charged with illegal voting, reflecting a troubling trend.
Neither Jian nor Liu applied for the necessary permits required by the U.S. Department of Agriculture for importing the fungus, making their actions illegal.
Two Chinese citizens, Yunqing Jian and Zunyong Liu, are facing serious charges in U.S. District Court in Detroit, including conspiracy and smuggling, for allegedly importing the harmful fungus Fusarium graminearum for research at the University of Michigan.
This case raises significant national security concerns, particularly regarding potential agricultural threats from China, especially given the country's military strategies that include biological warfare.
The charges come amid heightened scrutiny of Chinese nationals in the U.S., coinciding with recent visa restrictions affecting those studying in sensitive fields.
The investigation, which involved collaboration between the FBI and U.S. Customs and Border Protection, underscores the importance of safeguarding against biological threats.
FBI Special Agent Cheyvoryea Gibson emphasized that this case is a crucial step in ensuring public safety against the risks posed by the smuggling of biological pathogens.
Due to the lack of an extradition treaty with China, Liu's prosecution remains uncertain unless he returns to the U.S., complicating the legal proceedings.
While the University of Michigan is implicated in the case, it has denied any government funding related to the accused and stated its commitment to cooperating with federal investigations.
Jian's cellphone reportedly contained a pledge of loyalty to the Chinese Communist Party, indicating possible ties to state directives and raising further concerns about national security.
The FBI claims Liu smuggled the pathogen in July 2024, intending to clone strains for study at Jian's lab, highlighting the serious implications of their actions.
Justice Minister Pam Bondi stated that the accused faces severe penalties for attempting to introduce a destructive substance into the U.S., emphasizing the gravity of the situation.
