中国人排斥法
The Chinese Exclusion Act was a United States federal law signed by President Chester A. Arthur on May 6, 1882, prohibiting all immigration of Chinese laborers. Building on the earlier Page Act of 1875 which banned Chinese women from immigrating to the United States, the Chinese Exclusion Act was the first, and remains the only, law to have been implemented to prevent all members of a specific ethnic or national group from immigrating to the United States.
