Here is a long, but interesting article that shows how China groomed a federal reserve economist to spy for them:
How Chinese spies used lies, romance and betrayal to target the Federal Reserve
John Harold Rogers was walking Prada, his tiny spaniel, past a school bus stop in his suburban Washington neighborhood when FBI agents surrounded him. They handcuffed the former senior Federal Reserve official and took him into custody to face charges of spying for China.
An agent took Prada’s leash, and investigators from multiple federal agencies began an intensive search of Rogers’ house.
The now 65-year-old economist was arrested in January 2025, days before he was set to travel to China with his wife, a Chinese national, and their 6-year-old daughter. Investigators believed that Rogers passed information about the Fed to a Chinese government spy, who, over more than a decade, helped him with his career, his finances and his marriage to a woman 24 years his junior.
