What convinced other nations to agree on a open door policy with china?

The Open Door Policy in China, established in the late 19th century, was primarily motivated by the desire of Western powers to ensure equal trading rights and prevent any single nation from monopolizing trade in China. The economic interests of countries like the United States, which sought to secure access to Chinese markets, played a crucial role in fostering consensus among nations. Additionally, the policy aimed to maintain stability in the region and support China's territorial integrity, which resonated with multiple nations concerned about imperial competition. Ultimately, a combination of economic incentives and geopolitical considerations led to broad agreement on the Open Door Policy.
