U.S. Expert Decries Alleged Fungus Smuggling as 'Worse Than COVID', Urges Severing Ties with China

In a dramatic escalation of tensions between the United States and China, Gordon G. Chang, a prominent China expert, has condemned the alleged smuggling of a crop-damaging fungus into the U.S. as a threat more severe than the COVID-19 pandemic. Chang, who has extensive experience in China, characterized the actions of two Chinese researchers—Yunqing Jian and Zunyong Liu—as an "attack on the United States" and equated it to "waging war." He further urged the U.S. government to sever diplomatic relations with China to prevent further threats .(livemint.com)

The controversy centers on the fungal pathogen Fusarium graminearum, known to cause Fusarium head blight in crops like wheat and barley. While the fungus is endemic in the U.S., experts have raised concerns about the potential introduction of modified or resistant strains that could pose significant agricultural risks.(reuters.com)

The FBI alleges that Liu attempted to smuggle the fungus into the U.S. in July 2024, intending to conduct research at a University of Michigan lab where Jian worked. The lab reportedly lacked the necessary federal permits to handle such pathogens. Jian has been charged with conspiracy, smuggling, false statements, and visa fraud, while Liu remains at large in China .(livemint.com, thesun.co.uk, apnews.com)

Chang's remarks have sparked a broader debate. While some lawmakers and national security officials view the incident as a serious threat to U.S. food security, agricultural experts argue that the fungus is already present in the country and is manageable through existing agricultural practices .(livemint.com, reuters.com)

This development comes amid heightened scrutiny of Chinese influence in U.S. research institutions and growing concerns over national security.(nypost.com)
