Book excerpt: At the beginning of 1945, relations between America and the Chinese Communists couldn’t have been closer. Chinese leaders talked of America helping to lift China out of poverty; Mao Zedong himself held friendly meetings with U.S. emissaries. By year’s end, Chinese Communist soldiers were setting ambushes for American marines; official cordiality had been replaced by chilly hostility and distrust, a pattern which would continue for a quarter century, with the devastating wars in Korea and Vietnam among the consequences. In China 1945, Richard Bernstein tells the incredible story of the sea change that took place during that year—brilliantly analyzing its far-reaching components and colorful characters, from diplomats John Paton Davies and John Stewart Service to Time journalist, Henry Luce; in addition to Mao and his intractable counterpart, Chiang Kai-shek, and the indispensable Zhou Enlai. A tour de force of narrative history, China 1945 examines American power coming face-to-face with a formidable Asian revolutionary movement, and challenges familiar assumptions about the origins of modern Sino-American relations.
