The Chinese Communist Party (CCP) is violating the sovereignty of the United States through the creation of secret police stations on U.S. soil, according to FBI Director Christopher Wray.

“I’m very concerned about this,” Wray said during a Nov. 17 hearing of the Senate Homeland Security and Governmental Affairs Committee. “We are aware of the existence of these stations.”

“I have to be careful about discussing our specific investigative work, but to me it is outrageous to think that the Chinese police would attempt to set up shop—you know, in New York let’s say—without proper coordination. It violates sovereignty and circumvents standard judicial and law enforcement cooperation processes.”

Wray’s comments focused on the creation of China’s so-called “service stations,” which effectively act as overseas police stations for the CCP, which rules China as a single-party state.

The overseas police stations ostensibly serve administrative purposes normally entrusted to an embassy, including assisting Chinese immigrants with renewing driver’s licenses without having to leave the country.
