The Open-Door Policy was a diplomatic principle established in the late 19th century that aimed to ensure equal trading rights for all nations in China and prevent any single power from monopolizing trade there. It was rooted in the context of imperialism, as Western powers sought to expand their influence in Asia, particularly in China, which was seen as a vast market and a strategic area for territorial claims. The policy was articulated primarily by the United States and reflected broader themes of competition and intervention characteristic of the era.
