Overview
- Chengxuan Han, a PhD student from Wuhan, was detained at Detroit Metropolitan Airport on June 8 after shipping four packages containing biological material related to roundworms to contacts at a University of Michigan laboratory.
- Prosecutors say Han lied to Customs and Border Protection officers about the contents of her shipments and erased data from her electronic device days before her arrival.
- Han is the third Chinese national charged in Michigan in recent weeks, following Yunqing Jian and Zunyong Liu’s alleged attempt to smuggle Fusarium graminearum, a fungus that poses serious risks to cereal crops and livestock.
- The University of Michigan has confirmed its cooperation with federal investigators and condemned any actions that threaten public health or national security.
- FBI Director Kash Patel characterized the cases as part of a broader effort by the Chinese Communist Party to infiltrate U.S. research institutions and endanger America’s food supply.
