While in Washington, Burlingame negotiated a treaty with Seward to revise and expand upon the points established in the Treaty of Tianjin of 1858. The first few articles of the new treaty protected commerce conducted in Chinese ports and cities, and established the right of China to appoint consuls to American port cities. The more groundbreaking articles included measures that promised the Chinese the right to free immigration and travel within the United States, and allowed for the protection of Chinese citizens in the United States in accordance with the most-favored-nation principle. Another article gave the citizens of the two nations reciprocal access to education and schooling when living in the other country. All of these articles served to reinforce the principle of equality between the two nations.
The final article of the Burlingame-Seward Treaty offered China some protection from external influence in internal matters. In this article the U.S. recognized that the decision to begin new construction projects or similar improvements belonged in the hands of the local government, not foreign powers or their representatives. This point was intended to safeguard against undue U.S. involvement in Chinese domestic affairs.
Despite the reciprocal protections that the Treaty afforded Chinese in the United States and Americans in China, the Treaty ultimately reinforced U.S. trade interests with China under the principle of the most-favored-nation concept, and it ensured a steady flow of low-cost Chinese immigrant labor for U.S. firms. For these reasons, American industrial leaders initially celebrated the Treaty as a major advancement for American commercial interests.
However, the success of the treaty was short-lived. By the late 1870s, U.S. industrial leaders and politicians could no longer ignore the increasing anti-Chinese sentiment in the United States, particularly in the western states; in fact, industrialists and politicians often promoted anti-Chinese activities. A new treaty signed in 1880 revised the Burlingame-Seward agreement, and the Chinese Exclusion Act of 1882 abrogated its free immigration clauses altogether.
