CALIFORNIA – The U.S. Department of Justice (DOJ) announced May 30, indictments in California and Wisconsin against Cui Guanghai, 43 of China, and John Miller, 63, a U.K. citizen and U.S. resident, for interstate stalking, conspiracy, smuggling and Arms Export Control Act Violations.
“As alleged, the defendants targeted a U.S. resident for exercising his constitutional right to free speech and conspired to traffic sensitive American military technology to the Chinese regime,” said Deputy Attorney General Todd Blanche.
Blanche goes on to say that the Justice Department will not tolerate foreign repression on U.S. soil, nor will they allow hostile nations to infiltrate or exploit their defense systems.
Allegations in California
Court documents allege that starting October 2023, Cui and Miller recruited two individuals in the U.S. to stop the victim from protesting People’s Republic of China (PRC) President Xi Jinping’s appearance at the November 2023 Asia-Pacific Economic Cooperation (APEC) summit. The victim had previously criticized PRC policies and Xi.
Unbeknownst to Cui and Miller, the two individuals were FBI informants.
Before the APEC summit, Cui and Miller orchestrated a scheme to surveil the victim, install a tracker on their car, slash their tires, and destroy statues they created of Xi and his wife.
In spring 2025, after the victim announced plans to display new statues of Xi and his wife online, Cui and Miller paid $36,500 to two individuals to stop the display. Unbeknownst to them, these individuals were also FBI informants.
Allegations in Wisconsin
According to the court documents, in November 2023, Miller and Cui sought U.S. defense items, including missiles, drones and cryptographic devices, for illegal export to China through two individuals.
Cui and Miller planned to smuggle a cryptographic device to China by hiding it in household items and shipping it though Hong Kong. They paid a $10,000 deposit via courier and wire transfer.
U.S. is coordinating with Serbian authorities to extradite Cui and Miller
If convicted, Cui and Miller face up to 20 years for Arms Export Control violations, 10 years for smuggling, and five years for conspiracy and interstate stalking.
The FBI is investigating the case. The United States is coordinating with Serbian authorities regarding the pending extraditions of Cui and Miller from Serbia.
