A former CIA operative has raised concerns about China and Russia deploying “sex spies” to the United States. These operatives are allegedly tasked with acquiring technological information and state secrets through psychological manipulation.

Speaking to Fox News Digital, J. Michael Waller shared his firsthand experiences with these tactics, used by major adversaries like China and Russia. During his CIA assignment in Poland, Waller recounted an encounter with a young Chinese woman, approximately 25 years old, who expressed unusual interest in his activities.

Realizing her true intentions, Waller reported the woman to Polish authorities, leading to her swift expulsion from the country, as she was a government employee at the time. According to Waller, the woman was quickly deported within a few days.

Waller further explained that the Chinese operative seemed well-informed about his background, even possessing knowledge not included in his official biography for the event.

“They take advantage of the fact that people are lonely or just want to have a good time or, you know, need company or whatever else,” Waller said. “They do what’s been done since biblical times. They use sex as a weapon.”

Earlier this year, the U.S. government banned employees and personnel working in China from having romantic or sexual relationships with Chinese citizens. The policy was implemented by former U.S. Ambassador Nicholas Burns, who put the policy into place before leaving his post when President Donald Trump took office in January.

U.S. government personnel who violate the policy will be forced to leave China.

Waller said the practice is a form of psychological warfare because “you’re messing with people’s heads,” adding China will target professionals such as engineers, programmers, local officials, mayors or other politicians.

“They’ll go for a very long term with these sexual recruitments and develop long-term emotional relations, at least get the other side, get the target emotionally attached, to the point of even marrying them and having families with them,” he said. “That’s what they’re schooled to do.”

“It starts with love bombing — messages full of compliments, selfies, bikini photos,” Roza said. “They pretend to be weak or alone: ‘My parents were killed, I’m a student, I’m broke.’ It triggers the hero instinct. Every man wants to feel like the rescuer.”

The former CIA operative gave one piece of advice for Americans:

“If someone from China who’s super, super hot is really interested in you and you’re nowhere near in that league — she’s a spy,” Waller said.
