Nine essays discuss the first commercial encounters between a China on the verge of systemic social change and a United States struggling to assert itself globally as a distinct nation after the Revolutionary War, from the arrival in Canton of the first American ship in the 1870s, to the 1844 Treaty of Wangxia in Macao after the First Opium War, to Secretary of State John Hay's forging of the Open Door policy in 1899. Broad in scope, the essays are attuned to the activities of competing European traders, especially the British, in Canton, Macao, and the Pearl River Delta.
