What was one effect of the Burlingame Treaty?

The Burlingame Treaty was signed in 1868 between the United States and China. It aimed to strengthen diplomatic and commercial ties between the two countries. One effect of the treaty was that it improved U.S. and Chinese relations. The treaty allowed for Chinese immigrants to come to the United States and work, which helped to build the transcontinental railroad. However, the treaty did not end the discrimination and violence against Chinese immigrants in the United States. The Boxer Rebellion, which was a violent uprising against foreign influence in China, occurred more than 20 years after the signing of the Burlingame Treaty. The United States did not force European nations to open Chinese ports to trade, but rather negotiated its own trade agreements with China. Therefore, the correct answer is A.
