Two Foreign Nationals Arrested in Serbia for Directing Interstate Stalking and Harassment Scheme Targeting Los Angeles-Based Critic of Chinese President Xi Jinping

Yesterday, Serbian law enforcement authorities arrested two foreign nationals, Cui Guanghai, 43, of China, and John Miller, 63, of the United Kingdom, at the request of the United States. Today, the United States unsealed its criminal complaint alleging that Cui and Miller coordinated and directed a conspiracy to harass, intimidate, and threaten a Los Angeles resident (the Victim) who had been publicly critical of President Xi Jinping.

According to court documents, beginning in October 2023, Cui and Miller enlisted two individuals (Individual 1 and Individual 2) inside the United States to carry out a plot to prevent the Victim from protesting President Xi’s appearance at the Asia Pacific Economic Cooperation (APEC) summit in November 2023. The Victim had previously made public statements in opposition to the policies and actions of the PRC government and President Xi.

Unbeknownst to Cui and Miller, Individual 1 and Individual 2 were affiliated with and acting at the direction of the FBI.

In the weeks leading up to the APEC summit, Cui and Miller directed and coordinated an interstate scheme to surveil the Victim, to install a tracking device on the Victim’s car, to slash the tires on the Victim’s car, and to purchase and destroy a pair of artistic statutes created by the Victim depicting President Xi and President Xi’s wife.

A similar scheme took place in the spring of 2025, after the Victim announced that he planned to make public an online video feed depicting two new artistic statutes of President Xi and his wife. In connection with these plots, Cui and Miller paid two other individuals (Individual 3 and Individual 4), approximately $36,500 to convince the Victim to desist from the online display of the statues. Unbeknownst to Cui and Miller, Individual 3 and Individual 4 were also affiliated with and acting at the direction of the FBI.
