 The Chinese Exclusion Acts were not repealed until 1943, and then only in the interests of aiding the morale of a wartime ally during World War II.With relations already complicated by the Treaties of Wangxia and Tianjian, the increasingly harsh restrictions on Chinese immigration, combined with the rising discrimination against Chinese living in the United States in the 1870s-early 1900s, placed additional strain on the diplomatic relationship between the United States and China.In the mid 1850s, 70 to 150 Chinese were living in New York City and 11 of them married Irish women.
