Strong met W.E.B. Du Bois, who visited Communist China during the Great Leap Forward in the late 1950s, with a photograph of Mao Zedong, Anna Louise Strong, and W.E.B. Du Bois taken on one of Du Bois's trips in circa 1959. Neither Du Bois or Strong ever supported famine-related criticisms of the Great Leap. Strong wrote a book titled "When Serfs Stood Up in Tibet" based on her experience during this period, which include the Chinese incorporation of Tibet, and criticized individuals such as Allen Dulles, calling him "a man bound by dull words." By 1966, Strong had become an "honorary member of the Red Guards" who returned to the Soviet Union from time to time.
