The Gresham-Yang Treaty was a treaty signed between the United States of America and the Qing dynasty in 1894, in which the Qing dynasty consented to measures put in place by the United States prohibiting Chinese immigration in exchange for the readmission of previous Chinese residents, thus agreeing to the enforcement of the Geary Act.[1] This was the first time the United States government barred an entire ethnic group from entering the mainland United States of America.
The treaty lasted until 1904, when the Qing dynasty government exercised its right to unilaterally withdraw.[1]
