FBI Charges Former Michigan Scholar With Hiding His Chinese Military Drone Company From U.S. Customs

The FBI has charged Chuan Wang, a former University of Michigan visiting scholar, with lying to U.S. Customs and Border Protection officers about his work as co-founder and chief technology officer of a Chinese company that builds drones for the People’s Liberation Army. Wang, born in 1989, was charged Friday in U.S. District Court for the Eastern District of Michigan with one count of giving false statements, following an FBI counterintelligence investigation.

According to the criminal affidavit, Wang first entered the United States in 2012 on a J-1 visa to research solar aeroelastic aircraft wing design at U-M, then later founded Tianxun, a company that “designs and builds unmanned aerial vehicles (UAVs) and drones for the PRC military.” When CBP officers questioned him at Detroit Metropolitan Airport in 2023 as he attempted to fly back to Shanghai, he told them he worked for his father’s road sign company. It was unclear Saturday whether Wang remains in the United States.

A J-1 Scholar Visit That Started With Aircraft Wing Research

The affidavit traces Wang’s relationship with the United States to early 2012, when he received a J-1 visa to work as a research scholar at U-M from February 1 through August 31. On the application, Wang stated that a University of Michigan professor had invited him to research solar aeroelastic aircraft wing design and that he aimed to “develop a radio-controlled model airplane with high aspect ratio” and perform the related design, fabrication, test, flight, and analysis. The FBI says Wang already held an advanced degree in aircraft design from a Chinese university when he applied.

That stated research goal, a model aircraft with a high-aspect-ratio wing, sits at the same engineering boundary that produces long-endurance reconnaissance UAVs.

A Tourist Visa, A PLA Drone Company, And A Cover Story

After leaving Michigan, the affidavit says, Wang founded a company in China that “designs and builds unmanned aerial vehicles (UAVs) and drones for the PRC military.” In December 2014, he submitted a new visa application to return to the United States, this time for business or tourism. On that application, he listed his occupation as “related to the production of ‘commercials, movies, filming and postproduction editing'” for a media company, and said he had studied business administration. CBP issued him a 10-year visa that expired in 2025.

The FBI affidavit identifies Wang as co-founder and chief technology officer of Tianxun. Chinese-language news coverage cited in the affidavit describes Tianxun as a company that “promotes the application and development of UAVs and intelligent equipment manufacturing in the military and civilian markets.” One Chinese news article cited by the FBI contained an image showing Wang and other Tianxun employees standing in front of a UAV. A separate image released with the criminal complaint, which the filing says is believed to be Wang, shows a man in an orange life vest crouched beside a fixed-wing UAV on the deck of a vessel at sea.

Detroit News federal courts reporter Robert Snell, who has covered the broader U-M counterintelligence docket including the October 2024 Camp Grayling case, characterized the affidavit’s allegations on X as describing naval shipborne drones built for the Chinese military.

The 2023 Detroit Airport Stop That Lit The Fuse

On August 5, 2023, Wang attempted to leave the United States through Detroit Metro Airport on a flight to Shanghai, according to the affidavit detailed by The Detroit News. CBP officers searched and questioned him.

Wang told officers he had been in the country for 20 days visiting his parents and that he worked in China for his father’s road sign company, the affidavit states. He denied holding any patents related to military or defense applications. When CBP officers asked whether he had ever worked for any company involved in the production of aircraft or military equipment, Wang denied that as well.

Each of those statements was false, the FBI alleges. The bureau says open-source Chinese-language reporting connects Wang directly to Tianxun’s UAV programs, and that he has obtained “notoriety in Chinese news media and internet websites for being the co-founder of Tianxun.”

A Pattern Building Around Ann Arbor

The Wang charge does not stand alone. In October 2024, federal prosecutors charged five Chinese U-M graduates with conspiracy and false statements after they were found at Camp Grayling, Michigan’s National Guard training facility, during the Northern Strike exercise that hosted Taiwanese troops in 2023. All five returned to China before charges were filed and have never appeared in court. In June 2025, U-M visiting scholar Chengxuan Han was arrested at Detroit Metro Airport for smuggling biological materials and lying to CBP, and received a time-served sentence in September.

Two months before the Wang charge, U-M postdoctoral researcher Danhao Wang, no apparent relation, died on March 20, 2026 in what police are investigating as a self-harm incident inside U-M’s George G. Brown Building. Chinese Foreign Ministry officials publicly attributed the death to “hostile questioning” by U.S. law enforcement and condemned what they called a discriminatory enforcement pattern they say creates “a serious chilling effect” on Chinese scholars in the U.S.

I’ve been covering the U.S.-China drone counterintelligence beat since the 2024 Fengyun Shi case, in which a University of Minnesota graduate student was sentenced for using a drone to photograph Newport News naval shipyards. The pattern across cases is genuinely mixed. Some prosecutions, like the Indiana University case involving plasmid DNA initially mischaracterized as bacterial pathogens, have been criticized by named research scientists for misrepresenting harmless lab materials. Others, like the Camp Grayling case and the alleged conduct in the Wang affidavit, describe substantively different facts.

DroneXL’s Take

This is the case where the U.S. counterintelligence apparatus and the Chinese Ministry of Foreign Affairs are not, in fact, talking about the same kind of conduct.

Beijing’s framing has been steady through every U-M case: that CBP and the FBI are “groundlessly” interrogating Chinese scholars and creating a “serious chilling effect.” That argument lands when the underlying conduct is ambiguous. The Indiana plasmid case fits that pattern. So, arguably, did the early framing of Chengxuan Han’s roundworm-medium packages.

The Wang affidavit reads differently. It alleges a man who entered the United States on a J-1 academic visa to study aircraft wing design, went home, founded a company that openly markets UAVs to the People’s Liberation Army, then re-entered on a B-class visa using a media-production cover story. When confronted at Detroit airport in 2023, the FBI says, Wang denied his actual employer by name, denied his patents, and substituted his father’s road sign business for a company whose own publicity materials show him beside a military UAV. None of that is a routine plasmid permit dispute.

Two open questions matter most.

Whether Wang is currently in the United States is unanswered as of this writing. The five Camp Grayling defendants returned to China before they were charged and have never appeared in court. Wang’s 10-year visa expired in 2025, and the August 2023 stop happened on his way out of the country. If he has already left, this becomes another in-absentia indictment.

The second question is whether the Justice Department uses cases like this to harden the legal record on the China military-civil fusion drone pipeline that DroneXL has covered in reporting on Chinese university UAV programs and in documentation of Chinese drone makers’ work with sanctioned Russian arms maker IEMZ Kupol. That pipeline has been visible in open-source Chinese reporting for years. The DOJ now has a charging document that ties an individual case directly to that pipeline through one defendant’s own visa applications. Whether the affidavit’s specific evidentiary record holds up in court will determine how much weight it carries in the broader policy debate.

Beijing will continue to call this discriminatory enforcement. The U-M cases that fit that label and the ones that do not are now harder to lump together, and that, more than the headline charge itself, is what makes this filing matter for the drone-policy fight already underway in Michigan’s expanding role as a national drone war lab.
