What was the aim of the Open Door Policy?

The aim of the Open Door Policy was to ensure equal trading rights for all nations, particularly in China. This policy was articulated by U.S. Secretary of State John Hay in 1899, as a response to European powers establishing spheres of influence in China. The United States was concerned that it would be excluded from trade opportunities in the region. By advocating for the Open Door Policy, the U.S. sought to promote free access for all foreign nations to trade and conduct business in China, which was vital for American economic interests. This policy was fundamentally about preventing any single nation from monopolizing trade in China and fostering an environment where all countries could have equal opportunity in the growing markets of Asia.
