Two Chinese researchers, Yunqing Jian (33) and Zunyong Liu (34), face serious allegations in connection with the smuggling of a biological pathogen, specifically the fungus Fusarium graminearum, into the United States. The charges brought by the US Attorney’s Office for the Eastern District of Michigan include conspiracy to commit an offence, smuggling goods, providing false statements, and visa fraud. These allegations stem from their intent to conduct research at a university laboratory in the US.
Fusarium graminearum is regarded as a potential agroterrorism threat due to its detrimental effects on key crops like wheat, corn, rice, and barley, resulting in substantial economic losses globally. The fungus is also noted for producing toxins that can harm both livestock and humans, leading to symptoms such as vomiting and reproductive issues.
While the 25-page criminal complaint does not accuse Jian and Liu of intending to spread the pathogen beyond the University of Michigan, it does detail that Liu intentionally concealed the fungus in his backpack, embedded within tissues, indicating an awareness of legal restrictions.
Donell Harvin, a former homeland security chief, highlighted the dangers associated with handling such pathogens, asserting that regardless of intent, mistakes could lead to catastrophic consequences.
These charges come amidst ongoing scrutiny of Chinese nationals in the US, particularly in light of previous calls from US officials, including Secretary of State Marco Rubio, to revoke visas for students linked to the Chinese Communist Party or those studying sensitive disciplines. FBI Director Kash Patel remarked that this case serves as a stark reminder of the Chinese government’s efforts to infiltrate American institutions, particularly concerning threats to the food supply.
Though the court documents do not clarify Jian and Liu’s specific research intentions, Jian currently remains in FBI custody. A recent detention hearing was postponed to provide time for her new legal representation to prepare.
The Chinese Foreign Ministry has stated that they are unaware of the details surrounding the case but emphasised that the government encourages Chinese citizens abroad to abide by local laws while protecting their legitimate rights.
