History of China–United States relations
The history of the relations with China and the United States covers with the Qing and Republic eras.
Harold Isaacs in 1955 identified six stages of American attitudes toward China. They were "respect" (18th century), "contempt" (1840–1905), "benevolence" (1905 to 1937), "admiration" (1937–1944); "disenchantment" (1944–1949), and "hostility" (after 1949). In 1990, historian Jonathan Spence updated Isaac's model to include "reawakened curiosity" (1970–1974); "guileless fascination" (1974–1979), and "renewed skepticism" (1980s).
