In a striking bioterrorism case, the United States has charged two Chinese researchers with smuggling a devastating fungus into the country.

The alleged actions of the two Chinese scientists have escalated tensions, impacting both agricultural biosecurity and national security.
Accused of smuggling Fusarium graminearum, a detrimental fungus, into the U.S., the implications are vast for American crops and security initiatives.
The Trump administration remains vigilant in preventing espionage amidst the escalating conflict with China.
The U.S. Justice Department has charged Yunqing Jian and Zunyong Liu with attempting to smuggle Fusarium graminearum, a hazardous pathogen, into the U.S.
This fungus poses significant threats to maize, wheat, barley, and rice.
Prominent evidence suggests it was smuggled for experimentation at the University of Michigan.
Yunqing Jian, a researcher there, allegedly fortified these schemes under Chinese government influence, while Zunyong Liu, working at a Chinese university, admitted his role in facilitating this perilous incursion.
In a shocking discovery, Fusarium graminearum, notorious for causing head blight in winter wheat and affecting farmers across 32 states, threatens American agriculture.
The widespread impact can devastate the U.S. agricultural economy if not addressed promptly.
“The alleged actions of these Chinese nationals — including a loyal member of the Chinese Communist Party — are of the gravest national security concerns,” said U.S. Attorney Jerome F. Gorgon, Jr.
Yunqing Jian was apprehended in Detroit, whereas her co-conspirator, Liu, has reportedly returned to China, evading justice.
The FBI discovered WeChat messages confirming Jian’s direct involvement and deliberate deception attempts to mislead investigators.
Liu transported the concealed materials through Detroit Metropolitan Airport, which he initially denied but later confessed.
Amid strained relations between the U.S. and China, this case underscores concerted efforts to prevent the theft of sensitive information and bio-threats exacerbated by alleged espionage by Chinese academics.
U.S. authorities condemn these actions, emphasizing the significant risk posed to American citizens and asset protection.

“Today’s criminal charges levied upon Yunqing Jian and Zunyong Liu are indicative of CBP’s critical role in protecting the American people from biological threats that could devastate our agricultural economy and cause harm to humans; especially when it involves a researcher from a major university attempting to clandestinely bring potentially harmful biological materials into the United States,” declared U.S. Customs and Border Protection Director of Field Operations Marty C. Raybon.
In federal court, Jian must address her actions, confronting criminal charges and allegations of ideological allegiance to China.
While the case unfolds, it reminds citizens of lurking threats within critical sectors and strengthens resolve to guard American ingenuity and resources.
