The article outlines the development of relations between China and America, beginning from the arrival of America's "Huanghou Hao" [S.S. Empress of China] to 1989. In the beginning, trade relations were conducted in a friendly atmosphere, and based on an equal partnership and mutual benefit. Then, American businessmen participated in the opium trade, joined "the Eight-Power Allied Forces", and advocated the open-door policy. After World War II, America was involved in the Civil War between the Nationalist Party and the Communist Party. Since the establishment of the People's Republic of China, relations between China and America have always been complex, sometimes relaxed, sometimes hostile.
