Two Chinese nationals have been charged by the US Department of Justice for allegedly smuggling a dangerous biological pathogen into the United States for research purposes at the University of Michigan Laboratory. The Federal Bureau of Investigation (FBI) said the fungus, called Fusarium graminearum, could be used as a potential agroterrorism weapon.

According to the Justice Department release, Yunqing Jian (33) and Zunyong Liu (34) were charged in a criminal complaint with conspiracy, smuggling goods into the United States, making false statements, and visa fraud.

According to the release, the fungus causes "head blight", a disease of wheat, barley, maize, and rice, and is responsible for billions of dollars in economic losses.

China weaponised fungus?: From liver to reproductive harm

The fungus in question is Fusarium graminearum. It causes a plant disease known as 'head blight", which affects crops like wheat, barley, maize, and rice. It is known to cause billions of dollars in crop damage globally every year.

The US Department of Justice said the fungus can also harm humans and animals. It produces toxins that can lead to vomiting, liver damage, and reproductive problems.

In a release, the US Department of Justice said, “The FBI arrested Jian in connection with allegations related to Jian's and Liu's smuggling into America a fungus called Fusarium graminearum, which scientific literature classifies as a potential agroterrorism weapon. This noxious fungus causes 'head blight,' a disease of wheat, barley, maize, and rice, and is responsible for billions of dollars in economic losses worldwide each year. Fusarium graminearum's toxins cause vomiting, liver damage, and reproductive defects in humans and livestock.”

Chinese woman, boyfriend arrested for smuggling biological pathogen into US

According to the complaint, Jian received Chinese government funding for her work on this pathogen in China. Jian's electronics contain information describing her membership in and loyalty to the Chinese Communist Party (CCP).

The complaint alleged that Jian's boyfriend, Liu, works at a Chinese university where he conducts research on the same pathogen.

Jian first lied but then admitted to smuggling Fusarium graminearum into the US through the Detroit Metropolitan Airport in order to conduct research on it at the laboratory at the University of Michigan, where his girlfriend, Jian, worked, according to the US Justice Department release.

In the release, US Attorney Jerome F Gorgon Jr stated, “The alleged actions of these Chinese nationals--including a loyal member of the Chinese Communist Party--are of the gravest national security concerns. These two aliens have been charged with smuggling a fungus that has been described as a 'potential agroterrorism weapon' into the heartland of America, where they apparently intended to use a University of Michigan laboratory to further their scheme.”

Cheyvoryea Gibson, Special Agent in Charge of the FBI Detroit Field Office, said that these individuals exploited their access to laboratory facilities at a local university to engage in the smuggling of biological pathogens, an act that posed an imminent threat to public safety.

FBI Director Kash Patel also confirmed the arrest of a Chinese national in the US for allegedly smuggling a dangerous biological pathogen into the US. He called this case a "sobering reminder" that the CCP is working to deploy operatives and researchers to infiltrate American institutions and target the food supply in the US.

In a post on X, Patel stated, "New... I can confirm that the FBI arrested a Chinese national within the United States who allegedly smuggled a dangerous biological pathogen into the country. The individual, Yunqing Jian, is alleged to have smuggled a dangerous fungus called "Fusarium graminearum," which is an agroterrorism agent, into the U.S. to research at the University of Michigan, where she works. This fungus can cause a disease called "head blight," a disease of wheat, barley, maize, and rice, causing significant health issues in both humans and livestock. It is responsible for billions of dollars in economic losses worldwide each year. Evidence also indicates Jian had expressed loyalty to the Chinese Communist Party and had received funding from the Chinese government for similar work on this pathogen in China."

"Jian's boyfriend, Zunyong Liu -- also charged in the complaint -- works at a Chinese university where he conducts research on the same pathogen. Liu is alleged to have first lied, then admitted, to also smuggling Fusarium graminearum into America, through the Detroit Metropolitan Airport, so that he too could conduct research at the University of Michigan. Both individuals have been charged with conspiracy, smuggling goods into the United States, false statements, and visa fraud. This case is a sobering reminder that the CCP is working around the clock to deploy operatives and researchers to infiltrate American institutions and target our food supply, which would have grave consequences, putting American lives and our economy at serious risk. Your FBI will continue working tirelessly to be on guard against it. Our @FBIDetroit team did excellent work in this case, partnering with @CBP. Justice will be done," he added.

China deliberately engineered Coronavirus as a “bioweapon”?

A researcher in Wuhan had claimed that China deliberately engineered coronavirus as a "bioweapon". The explosive claim was made by Chao Shan in an exclusive interview with Jennifer Zeng, a member of the International Press Association, who provided first-hand information and unique insights about China and the Chinese Communist Party (CCP). Chao said he and his colleagues were tasked with identifying the most effective strain for spreading among various species, including humans.

COVID-19 pandemic origin: Bioweapons and the history of lab leaks

From the early stages, wild speculation existed regarding the origins of the virus. In March 2020, the US Department of State summoned the Chinese ambassador to protest statements of a Chinese spokesperson, who suggested that the virus was brought to Wuhan by the US military, allegedly as a bioweapon.

Then, a US senator suggested that the virus resulted from a botched Chinese bioweapons program.

Palestinian media argued that SARS-CoV-2 was a biological weapon being used by the US and Israel against China and Iran.

Other US officials suspected that the virus came from a Wuhan laboratory that was performing legitimate viral research because safety concerns had been previously identified at this laboratory.

As time went on, concern grew because China was found to be censoring the results of research into the origins of the pandemic.

It was not the first time that modern research in China drew attack. In late 2018, the announcement of gene editing of babies resulted in criminal charges against a Chinese biophysicist and his two colleagues.

These issues have served to maintain alternative possibilities for the origin of COVID-19, based mostly on conspiracy theories and rumors that spread quickly through social media and remain difficult to stop.

The virus as a bioweapon and the possible laboratory leak from legitimate research are the two most common theories about the origins of SARS-CoV-2.
