\nJust last week we had a pair of Chinese nationals charged with trying to smuggle a biological hazard into the US.
Yunqing Jian, 33, and Zunyong Liu, 34, citizens of the People\u2019s Republic of China, were charged in a criminal complaint with conspiracy, smuggling goods into the United States, false statements, and visa fraud, announced United States Attorney Jerome F. Gorgon, Jr.
The FBI arrested Jian in connection with allegations related to Jian\u2019s and Liu\u2019s smuggling into America a fungus called Fusarium graminearum, which scientific literature classifies as a potential agroterrorism weapon. This noxious fungus causes \u201chead blight,\u201d a disease of wheat, barley, maize, and rice, and is responsible for billions of dollars in economic losses worldwide each year. Fusarium graminearum\u2019s toxins cause vomiting, liver damage, and reproductive defects in humans and livestock.
Today, we’re learning a third Chinese national has been arrested for another attempt to smuggle biological material into the US.
Yesterday, @FBIDetroit arrested a second Chinese national on charges of smuggling biological materials into the U.S. and lying to federal agents.

This individual is Chengxuan Han, a citizen of the People\u2019s Republic of China and a Ph.D. student in Wuhan, China. Han is the third PRC connected individual charged on similar allegations in recent days.
Han is alleged to have sent four packages to the U.S. from China containing a biological material related to round worms \u2014 addressed to individuals associated with a lab at the University of Michigan.
Upon arriving at the Detroit Metropolitan Airport on June 8, Han allegedly made false statements to federal officials regarding the packages she had previously mailed \u2014 and had erased her electronic device just days prior.
In a follow up interview with FBI and ICE HSI agents, Han admitted to sending the packages and lying about their contents.
This case is part of a broader effort from the FBI and our federal partners to heavily crack down on similar pathogeon smuggling operations, as the CCP works relentlessly to undermine America\u2019s research institutions.
At the moment no one seems to be saying these cases are connected though both of them involve Chinese nationals and the University of Michigan. The samples which Han sent to the university are not believed to be dangerous in this case.
The court filing doesn\u2019t indicate whether the FBI believes the biological material was risky, though US attorney Jerome Gorgon Jr said smuggling \u201cthreatens our security\u201d.
The scientist remains in custody awaiting a bond hearing on Wednesday.
\u201cIt doesn\u2019t strike me as something that is dangerous in any way. But there are rules to ship biological material,\u201d said Michael Shapira, a biologist at the University of California, Berkeley, who read the court filing and spoke to the Associated Press.
So maybe not as dangerous as the incident revealed last week but still you have to wonder why this person erased her phone three days before traveling to the US. That really does seem suspicious. Also, Han had been denied entry twice in March.
Han was denied a visa to travel to the US on two separate occasions in March. In one of her attempts to obtain a visa, Han \u201ccould not clearly answer basic questions about herself or her research,\u201d according to court documents.
An offer letter from the University of Michigan stated that Han was invited to be a visiting scholar at the lab.
The University of Michigan probably needs to clean up these laboratories and make sure there are no more CCP members working under their noses. At this point, there is every reason to think China sees us as an adversary they would like to bring down by any means necessary, including by contributing directly to the murder of Americans. Here’s a bit of what FBI Director Patel said about the CCP’s connection to the fentanyl trade last week.
