Federal officials said two foreign nationals were accused of stalking a Los Angeles artist who criticized Chinese president Xi Jinping.

Kuy, 43, of China, and John Miller, 63, of the United States, and legal permanent residents are charged with interstate stalking, conspiracy to commit interstate stalking, smuggling and violation of the Arms Export Control Act, according to a release by the U.S. attorney in central California.

"The defendant allegedly planned harassment and interference in a person who criticized the People's Republic of China while exercising his constitutionally protected right to free speech within the U.S.," FBI Deputy Director Dan Bongino said in a press release. "The same person is also responsible for attempting to acquire and export sensitive U.S. military technology to China."

If convicted, CUI and Miller face up to five years in prison for conspiracy, five years of interstate stalkers, 20 and 10 years of smuggling in violation of the Arms Export Control Act.

According to court documents, CUI and Miller allegedly hired two people, who did not recognize were acting in the direction of the FBI to prevent someone from protesting against the emergence of XI at the Asia-Pacific Economic Cooperation Summit in the Asia-Pacific region. The victim was not named in the issuance and has previously publicly criticized Xi Jinping and the Chinese government.

According to the press release, Cui and Miller investigated the victims, installed a tracking device on their cars, cut tires on the car, and bought and destroyed the statues created by the victims, which showed Xi Jinping and XI's wife.

In spring 2025, the victim announced that he plans to promote an online feed of the two statues. Officials wrote that Kui and Miller allegedly paid $36,500 to two others to convince the victims not to display the statue. The two men also worked with the FBI.

Miller and Kuy allegedly purchased U.S. defense articles, including air defense radars, drones, missiles and encryption equipment, to illegally export them from the United States to China. They talked with two other people about how to export the device, including hiding it in a blender, a car starter, small electronics or shipping it to Hong Kong.

Officials said CUI and Miller allegedly paid about $10,000 in deposits to crypto devices through couriers in the U.S. and transferred wire transfers to U.S. bank accounts.
