A Chinese researcher allegedly tried to smuggle biological materials into the US from Wuhan and lied to the feds about the secretive scheme.

Chengxuan Han was arrested Sunday after landing at the Detroit Metropolitan airport on a flight from Shanghai, according to charging documents. She was charged with smuggling goods into the US and making false statements.

Han is the third Chinese scientist to be charged with smuggling illegal biological materials into Michigan in recent weeks.

Yunqing Jian, 33, and her boyfriend Zunyong Liu, 34, were caught last year allegedly trying to smuggle samples of a dangerous crop-killing fungus into the US, the FBI said. Jian, a Communist Party loyalist and lab researcher at the University of Michigan who received Chinese government funding for her work, was charged last week in a ploat the national security insiders called “an attack on US food supply.”

Upon Han’s arrival to the US, border officers discovered Han sent four packages that “contained biological material related to round worms” from China, according to court documents

The packages, which were sent in both 2024 and 2025, were addressed to individuals associated with a laboratory at the University of Michigan.

Is the Defense Department still preparing to fight biological warfare as if it’s 1970?

When preparing for biological warfare, most nations picture scenarios in which an enemy openly sprays traditional agents over wide areas to kill their adversaries.  However, revolutionary capabilities in the life sciences and biotechnology have transformed the threat. China’s approach to warfare, combined with these emerging technologies, reveals new vulnerabilities among Western forces that, to date, have not been fully acknowledged. In no small measure, this is due to the U.S. government’s continued reliance on a 20th-century strategy for countering weapons of mass destruction. In particular, as China is a major nuclear power, it cannot be threatened after it uses biological weapons as easily as a non-nuclear state. Given these points, can China be deterred from using such advanced biological weapons during a regional crisis in the Indo-Pacific, especially an invasion of Taiwan? And if not, is it possible to mitigate the damage from such a scenario?

Although Western attention has focused on the rapid expansion of China’s nuclear and conventional warfighting capabilities, one ought to expect equal analysis of China’s biological warfare potential. By examining China’s most recent efforts at biological research, we put forward that it has bypassed 20th-century Western concepts of biological warfare and has new capabilities that could be effective across the entire conflict spectrum. Given China’s new capabilities and nuclear arsenal, we assess that standard strategies of deterrence and protection likely will not work in the future. New approaches and new concepts will be necessary if the United States is to prepare itself for potentially new forms of biological warfare in the 21st century.

This is the third Chinese national accused of smuggling biological materials into Michigan. Despite last week’s arrest of Chinese agroterrorists, China continues to wage bio-war on the United States.

Authorities say Chengxuan Han is a doctoral student at the College of Life Science and Technology in the Huazhong University of Science and Technology in Wuhan, China.

Agroterrorist Han is from Huazhong University of Science and Technology, which works closely with China’s military and defense industry.

On June 8, Chengxuan Han was stopped by U.S. Customs and Border Protection officers at Detroit Metropolitan Airport after arriving on a J1 visa. Officers inspected Han, who, during that time, reportedly lied to officials about the packages and the biological materials she is accused of previously sending to the U.S. Officers say Han related content from an electronic device three days before arriving in the U.S.

For the second time this month, federal officials have announced the arrest of a Chinese researcher who sought to bring biological material into Michigan.

Chengxuan Han has been charged with smuggling goods into the United States and false statements, United States Attorney Jerome F. Gorgon, Jr. said Monday, according to a Department of Justice news release.

The news release noted that Han is based in Wuhan, the epicenter of the COVID-19 outbreak, where she is a researcher at the College of Life Science and Technology in the Huazhong University of Science and Technology.

On Sunday, Customs and Border Protection officers at Detroit Metropolitan Airport detained Han, who allegedly lied about shipments of biological material she had earlier sent to a laboratory at the University of Michigan.

Two Chinese researchers were allegedly involved in what could have developed into an attack on America’s food supply.

Yunqing Jian, 33, and Zunyong Liu, 34, were charged with conspiracy, smuggling goods into the United States, false statements, and visa fraud, according to a Department of Justice news release.

The release said they are accused of “smuggling into America a fungus called Fusarium graminearum, which scientific literature classifies as a potential agroterrorism weapon.”

According to the release, China’s communist government funded Jian’s research in China. The complaint said that when law enforcement scanned her electronic devices, they found documentation of her membership in and loyalty to the Chinese Communist Party. Liu, who has claimed he was Jian’s boyfriend, also conducted research on the same pathogen.

Liu has admitted to authorities that he smuggled Fusarium graminearum into America to conduct research with Jian.

National security authorities and members of Congress are raising alarm over the alleged plot by two romantically involved Chinese researchers to smuggle samples of a dangerous crop-killing fungus into the US.

Yunquing Jian, 33, a Communist Party loyalist and lab researcher at the University of Michigan who received Chinese government funding for her work, plotted the illicit transport of the pathogen with her boyfriend, Zunyong Liu, 34, the FBI alleged.

Liu was was caught at Detroit Metropolitan Airport last July after allegedly attempting to sneak packages of Fusarium graminearum into the country, the feds said.

“This is an attack on the American food supply,” one senior Trump administration official told The Post.

WASHINGTON: Two Chinese scientists have been charged with allegedly smuggling a toxic fungus into the United States that they planned to research at an American university, the Justice Department said on Tuesday (Jun 4).

Yunqing Jian, 33, and Zunyong Liu, 34, are charged with conspiracy, smuggling, false statements, and visa fraud, the US Attorney’s Office for the Eastern District of Michigan said in a statement.

Jian is in US custody while Liu’s whereabouts are unknown.

The Justice Department said the pair conspired to smuggle a fungus called Fusarium graminearum into the US that causes “head blight”, a disease of wheat, barley, maize and rice.
