How many Chinese researchers are smuggling dangerous materials into the United States?
Who knows? But the answer is that at least six have been arrested this year, all associated with a University of Michigan laboratory, and all with potential links to bioterrorism.

Let that sink in. As we debate the wisdom of allowing massive numbers of Chinese "students" into the United States, we keep getting news about Chinese "scholars" importing dangerous biological materials that can be weaponized into the country.
Three were arrested earlier this year, smuggling in a fungus that is ideal for use as a biological weapon against our agriculture industry, and three more were arrested yesterday, as they were trying to flee the country using what are obviously elaborate intelligence agency tactics.
After Han’s arrest and removal from the United States, UM initiated an internal investigation into the Shawn Xu laboratory. All three defendants refused to attend a mandatory meeting or participate in the investigation and so were terminated. This termination made them eligible for removal by the Department of Homeland Security.
The defendants purchased airline tickets to depart the United States from Detroit Metropolitan Airport (DTW) to the PRC on October 20, 2025. On October 10, 2025, federal agents attempted to locate the defendants at their home and elsewhere but were unsuccessful. That same day, the defendants rebooked their flights for October 15, 2025. They also booked flights to the PRC departing from John F. Kennedy International Airport for 2:00 a.m. on October 16, 2025. The defendants did not cancel or show for their DTW flight on October 15, 2025. Defendants instead traveled to New York and attempted to board the early morning JFK flight to the PRC on October 16. During an inspection by CBP, Z. Zhang made false statements about Han. Bai and F. Zhang told CBP officers they had received packages from Han including after her arrest or removal from the United States.
Sounds totally normal. Who doesn't disappear from the radar and book wildly expensive tickets at multiple airports in order to escape the country after being caught smuggling genetically engineered roundworms into the country?

Nothing to see here. Look away.
DETROIT, Mich – Three research scholars from the People’s Republic of China (PRC) were charged today in a criminal complaint with conspiracy to smuggle biological materials into the United States and for making false statements to U.S. Customs and Border Protection Officers, announced United States Attorney Jerome F. Gorgon, Jr. These are the latest charges in a long string of cases stemming from University of Michigan (UM) international research activities.
“Allegedly attempting to smuggle biological materials under the guise of ‘research’ is a serious crime that threatens America’s national and agricultural security,” said Attorney General Pamela Bondi. “We will remain vigilant to threats like these from foreign nationals who would take advantage of America’s generosity to advance a malicious agenda.”
“At some point, pattern becomes practice. And, apparently, these three men are part of a long and alarming pattern of criminal activities committed by Chinese Nationals under the cover of the University of Michigan. This is a threat to our collective security. We are thankful for the vigilance of our elite federal partners—ICE HSI, FBI, and CBP—as a counterweight against this threat,” said United States Attorney Gorgon.
Charged were Xu Bai, 28, Fengfan Zhang, 27 and Zhiyong Zhang, 30. Bai and F. Zhang were charged with conspiracy to smuggle biological materials into the United States and Z. Zhang was charged with making false statements to federal agents. All three men were research scholars holding J-1 visas who were conducting research at the UM laboratory of Xianzhong Xu, commonly referred to as the Shawn Xu laboratory.
According to the criminal complaint, in 2024 and 2025, Bai and F. Zhang were the recipients of multiple shipments containing concealed biological materials related to round worms which had been sent from the PRC to the United States by Chengxuan Han, a citizen of the PRC. Han was pursuing a Ph.D. from the College of Life Science and Technology in the Huazhong University of Science and Technology (HUST) in Wuhan, PRC and in June 2025, traveled to the United States to work in the laboratory at UM. Han recently pleaded no contest to three counts of smuggling and one count of false statements, was sentenced and then removed from the United States.
I looked up how many cases there have been this year, and Grok returned this:
We now have parallel police organizations in the United States run by the Chinese Communist Party. Students are blackmailed by the Chinese Communist Party to spy while they are here in the United States. And the Chinese have completely infiltrated our telecommunications infrastructure and are attacking our grid as well.

Clearly, China is waging a "gray zone" war against the United States.
There was a time when it was not difficult to argue that America got more than China did by admitting Chinese students into our universities. They are among the best of the best, and many chose to stay.
But that case is no longer easy to make. Chinese students and researchers are blackmailed into spying for China, and many of these people are clearly agents of the CCP.
You don't smuggle in bioweapons with good intentions.
