“Fang Fang” was laser-focused on her target: An obscure California congressman named Eric Swalwell.

Newly released FBI files reveal that the suspected Chinese spy used sex to seduce the Bay Area Democrat.

Moscow, Beijing and other hostile players have long employed venomous vixens to seduce power players. Some women do it for the money, others for adventure.

Some, like infamous flame-haired Russian spy Anna Chapman, are driven by patriotism.

“People were enamoured with her. She knew what she was doing — she was a social climber,” former beau Nicholas Camilleri told The UK Sun.

“She had very good looks and a very nice personality. She was charming. She was a listener, and she had a good sense of humour.”

Sex as geopolitical weapon

Camilleri had no idea that Chapman’s heart belonged to Mother Russia. Other honeytrap spies share Chapman’s looks and charm.

Since time immemorial, sex has been deployed as a geopolitical weapon.

Swalwell was merely its latest victim. He copped to a drug-fueled sex romp with Christine Fang, aka Fang Fang, admitting to sex with her on at least two other occasions. In the Golden State as a student, she allegedly had orders from Chinese intelligence to make things happen.

One of Swalwell’s campaign aides told the feds in 2015 that Fang Fang was “very flirtatious” telling the congressman upon arrival at his apartment “that she was not wearing any underwear.”

Swalwell was an ideal target as a member of the House Intelligence Committee until he was booted in January 2023 after his carnal capers with Fang became known. His career only came off the rails in April when he was accused of rape and sexual assault by multiple women.

According to the New York Post, Fang had been a suspected agent for the Chinese Communist Party’s Ministry of State Security (MSS). She wormed her way into Swalwell’s political apparatus, organizing fundraisers and cultivating relationships with other young politicos.

Urged politician to visit China

The newly declassified documents said Fang even encouraged her political paramour and his family to visit China. The alleged spy also placed an intern in Swalwell’s Washington office before the young woman moved on to a different congressman. It wasn’t clear if the intern was a Chinese intelligence operative.

Swalwell’s lawyer told the Post he did nothing wrong. As for Fang Fang, she got out of the U.S. and fled to China in 2015 just as the FBI began investigating her. It later emerged that Fang Fang also engaged in sexual antics with two Midwestern mayors.

Christine Fang followed on a well-trodden path that has wound its way from ancient Troy to the Western Front during the First World War to modern New York City.

Ian Fleming could have created Anna Chapman

Striking Anna Chapman could have emerged from the fertile mind of James Bond creator, Ian Fleming.

Just 20 years old when she began unleashing her seductive charms across London society, Chapman boasted a luxurious head of flowing red hair, penetrating green eyes and smouldering looks.

She got a lot of attention.

What London’s powerful didn’t know was that Chapman had been dispatched to the UK to spy for Russia. Neo-Czar Vladimir Putin would later hail her as a hero.

Born Anna Vasilyevna Kushchenko, the mysterious beauty met British DJ Marcus Read in Zimbabwe. He was immediately smitten with the young Russian.

‘Her dad was in the KGB’

“She was highly seductive. I hadn’t met any girls with that power,” he told The UK Sun. “I realized she was Russian and that made the whole thing quite exciting.”

He added: “We were sharing the same bed on the first night. It was like we were meant to be together. The only thing that struck me was when she told me her dad was in the KGB.”

From the DJ, she moved on to a slew of different men, marrying a record executive named Alex Chapman. And now she had a British passport.

“There were Russians everywhere — bankers, property owners, investors, hedge fund managers. And there were lots of Russian women,” Camilleri said.

One was Anna Chapman.

‘She was very dangerous’

In 2010, she moved to the U.S. In America, she attracted the attention of the FBI, who began daily surveillance believing that she was posing as a real estate agent, selling New York City properties to Russians.

“She was pretty uneventful ­during the day at first. Just a normal 28-year-old going shopping at the store, doing yoga,” former FBI agent Ed Foley said. “But at night it was a different story. She would get shuttled around in high-end limos, dressed to the nines, going to clubs that were VIP-only.

“She was, in fact, quite literally in bed with some of the top Wall Street financiers, people who had influence in political circles, city planning, finance. She was very dangerous because she was ­mission-driven and did whatever it took with whomever it took to get whatever she needed for the betterment of the Russian intelligence service.

“Seduction is the oldest trick in the book, right? She knew exactly what she was doing.”

That surveillance paid off and agents discovered she was one of 10 in a Russian spy ring. They were all arrested. Chapman eventually went home as part of a spy swap where she became a regular on talk shows and a Maxim covergirl.

Today she is head of the Museum of Russian ­Intelligence, celebrating the country’s long-running espionage operations against the West.
