Two individuals have been charged in connection with a scheme to smuggle U.S. military technology, including missiles, to China, as reported by the U.S. Department of Justice. The defendants, Guang Guy, 43, and John Miller, 63, both from England, face multiple charges like interstate stalking and conspiracy. This development aligns with President Trump’s administration’s intensified scrutiny of visa applicants, particularly from China.
Prosecutors allege that CUI was acting on behalf of the Chinese government. Court records indicate that since November 2023, both CUI and Miller have attempted to acquire military gear such as drones, air defense radars, and cryptographic devices. It appears they coordinated with others, possibly connected to the FBI, to export those encryption devices to China.
They reportedly discussed methods for concealing these devices, suggesting they could hide them within ordinary electronics. Allegedly, they also paid a deposit of $10,000 on one encryption device. In a separate but related aspect, court documents reveal they aimed to recruit individuals to target U.S. citizens who had opposed Chinese President Xi Jinping during an upcoming summit.
The alleged plot included plans to stalk and surveil these citizens, alongside malicious acts like slashing tires and damaging statues related to Xi. However, the people they purportedly recruited were actually cooperating with the FBI.
Deputy Attorney General Todd Blanche commented that these actions represent a clear violation of U.S. national security and a threat to democratic principles. CUI and Miller were arrested in Serbia in April at the U.S. government’s request and are awaiting extradition. If convicted, they could face a range of sentences, potentially totaling decades in prison depending on the outcomes of their charges.
The Chinese embassy did not respond to requests for comments, while a representative from the UK’s Foreign, Federal and Development Office noted that they are providing assistance to Miller following his arrest. Meanwhile, the State Department is introducing new measures to tighten visa application screenings, particularly for those from China and Hong Kong.
