Two Chinese nationals have been busted in separate but equally chilling plots that involve smuggling biological materials into the U.S. and funneling American weapons to North Korea, according to the Department of Justice.
In the first case, 27-year-old Chengxuan Han, a Ph.D. student from Wuhan, was arrested at Detroit Metropolitan Airport after allegedly smuggling biological samples and deleting key evidence from her electronic devices just days before arriving. Han admitted to lying to border officials and confessed to sending concealed biological material—specifically involving roundworms—from China to a University of Michigan lab.
The DOJ revealed she was affiliated with Huazhong University of Science and Technology in Wuhan—the same city where the COVID-19 pandemic began. “This is part of an alarming pattern that threatens our security,” said U.S. Attorney Jerome Gorgon Jr. “The American taxpayer should not be underwriting a PRC-based smuggling operation at one of our crucial public institutions.”
The second case is even more disturbing.
Shenghua Wen, a 42-year-old Chinese national who overstayed his student visa by a decade, has pleaded guilty to federal charges after acting as an agent of North Korea. Wen was working directly under orders from Pyongyang, helping ship containers of firearms, ammunition, and sensitive military technology from the U.S. to North Korea through China.
Wen purchased a gun store in Houston, Texas, using North Korean money. He then transported the weapons to California, where they were shipped out of the Port of Long Beach to Hong Kong before reaching North Korea’s Nampo Port.
Prosecutors say Wen tried to send 60,000 rounds of 9mm ammo in one shipment and admitted to acquiring advanced gear like thermal imaging devices, broadband receivers for intercepting communications, and a civilian airplane engine that could be repurposed for military use.
Wen received nearly $2 million from North Korea for his operations and took deliberate steps to hide the nature of the shipments. He admitted in court that he knew he was violating U.S. export laws and failed to notify the Attorney General of his work on behalf of a foreign government.
Federal agents also seized surveillance equipment from his home.
The coordinated efforts of both individuals represent more than isolated crimes—they reflect a broader strategy by the Chinese Communist Party and its allies to undermine U.S. sovereignty and exploit American institutions.
These revelations come as former President Trump and FBI Director Kash Patel continue warning the public about foreign nationals abusing the U.S. visa system. The same day these arrests were made, Patel told podcaster Joe Rogan that China is deliberately waging a chemical war through fentanyl distribution, targeting American youth to weaken the nation long-term.
Now we learn the threat also includes covert bioweapon activity and military espionage.
Under Trump’s leadership, the DOJ is finally taking the threat seriously. Both Han and Wen face long prison sentences—up to 30 years combined. But this is just the beginning of uncovering how deeply China and its proxies have infiltrated America.
From smuggling biolabs to arming U.S. enemies, the CCP’s aggression is not theoretical. It’s here. It’s now. And it’s happening under the noses of a complacent, open-borders administration.
The arrests are a warning. The question is: will Washington finally act like it heard it?
