A visit to Spain resulted in "Spain in Arms" (1937); visits to China, visiting anti-Japanese "base areas," leading to her book "One Fifth of Mankind" (1938). In 1940, she published "My Native Land", the same year that she went to China and met Zhou Enlai several times. The following year, she exposed the plot by Chiang Kai-Shek to divide the "united front" against Japan in the 15-page article, "The Kuomintang-communist crisis in China; a first-hand account of one of the most critical periods in Far Eastern history" published in March. Other books include "The Soviets Expected It" (1941); the novel "Wild River" (1943), set in Russia; "Peoples of the U.S.S.R." (1944), "I Saw the New Poland" (1946) (based on her reporting from Poland as she accompanied the occupying Red Army); and three books on the success of the early Communist Party of China in the Chinese Civil War. In her book "The Soviets Expected It", Strong wrote that "the unbroken rise of Stalin's prestige for twenty years both within the Soviet Union and beyond its borders is really worth attention by students of politics."
