DETROIT – Two Chinese nationals with ties to the University of Michigan are scheduled to appear in federal court on Friday, marking the latest development in what some authorities describe as an intensifying crackdown on biological material smuggling cases.
The court appearances come amid a series of arrests that have revealed three Chinese nationals facing federal charges in two separate cases within a two-week span, all connected to the University of Michigan’s laboratory facilities.
Mounting Security Concerns
Federal authorities have charged Yunqing Jian, 33, and her boyfriend Zunyong Liu, 34, with smuggling a potentially dangerous fungus known as Fusarium graminearum. The pathogen can cause significant crop damage through a condition called “head blight,” affecting wheat, barley, maize and rice.
In a separate case, Chengxuan Han, a doctoral student from Wuhan, China, faces charges related to smuggling biological materials into the United States. Federal investigators allege Han sent four packages containing concealed biological material related to roundworms to individuals working in a University of Michigan laboratory.
Scientific Debate Over Threat Level
While federal authorities emphasize the security concerns, plant pathology expert Caitilyn Allen offers a different perspective on the Fusarium graminearum case.
“Maybe it’s been hyped a little bit,” Allen said, noting that the fungus is relatively common.
However, she acknowledges its potential impact on crops and livestock, which could have broader economic implications.
Enforcement Strategy
“We are going to have more of these cases in the future. It’s not going away any time soon,” former U.S. Attorney Matthew Schneider told Local 4.
The recent arrests reflect what authorities describe as a broader crackdown on unauthorized transfer of biological materials.
University Response
The University of Michigan has responded to these incidents with the following statement:
“As one of the world’s leading public research institutions, the University of Michigan is dedicated to advancing knowledge, solving challenging problems and improving nearly every facet of the human experience.
Our research enterprise across all three campuses is united in this commitment to serving the people of Michigan and the world.
We strongly condemn any actions that seek to cause harm, threaten national security or undermine the university’s critical public mission.
It is important to note that the university has received no funding from the Chinese government in relation to research conducted by the accused individuals.
We have and will continue to cooperate with federal law enforcement in its ongoing investigation and prosecution."

Legal Expert Analysis
The cases highlight growing concerns about research security at American universities.
Former Wayne County Circuit Judge Vonda Evans noted the evolution of security threats, stating, “Now, terrorism has potentially gone agroterrorism. We’ve seen terrorism of all sorts come through.” Evans praised the vigilance of enforcement efforts, suggesting that without such oversight, these materials “could’ve gotten through.”
FBI Warning
The FBI has expressed particular concern about the Fusarium graminearum case, with the agency’s director highlighting the fungus’s potential to cause significant agricultural damage and health issues in both humans and livestock.
While both Jian and Han are scheduled for federal court appearances in Detroit, Liu has reportedly returned to China.
