First Encounter and Immediate Suspicions of U.S. Intelligence Activity

This event, which occurred in late 2018 or early 2019, is being published for the first time on this website on May 17, 2025.
In late 2018 or early 2019, but most likely at the end of 2018, my wife met two individuals that I will only identify publicly as [Subject #2 - a U.S. intelligence operative in China] and [Subject #3 - a U.S. intelligence operative in China, wife of Subject #2]. Upon returning home from this initial encounter, she immediately shared her suspicions with me, explicitly wondering whether they might be associated with U.S. intelligence. At the time, I completely dismissed her suspicions, believing instead that they were merely Christian missionaries. My wife, being a Chinese citizen, was meeting Christian missionaries for the first time in her life, which understandably raised her suspicions. However, having grown up in a Catholic family and having previously encountered missionaries, I personally found their presence and activities perfectly normal.
