Oregon Man Admits Paying U.S. Soldiers for Information on HIMARS, Bradley and Stryker Systems Sent to China
Ruoyu Duan of Hillsboro, who trained as a U.S. Army soldier to handle sensitive classified military information, has pleaded guilty to transmitting national defense information to China.
Forty-one-year-old Duan will be sentenced by U.S. District Court Judge Karin Immergut in Portland on December 10. He faces up to 10 years in prison and a $250,000 fine.
According to court documents, between November 2021 and March 2025 |Duan conspired with others to surreptitiously gather sensitive military information.
These included the U.S. Army’s operational capabilities, computer equipment, training materials, intelligence reports, and technical manuals.
Information Specifically Related to U.S. Military Weapons Systems Was Obtained
Working with active-duty U.S. Army soldiers, Duan, who served in the military from 2013 to 2017, paid his conspirators to obtain information specifically related to U.S. military weapons systems such as U.S. Army combat vehicles, including the Bradley, Stryker, and HIMARS platforms.
He then transferred this information to people in China.
On March 5, 2025, a federal grand jury in Portland returned an indictment charging Duan and Li Tian, an active-duty U.S. Army Officer, with conspiracy to commit bribery and theft of government property.
The FBI arrested Duan in Oregon on March 6, 2025.
