Why did the US propose the the open door policy how was it received?

The US proposed the Open Door Policy in the late 19th century to ensure equal trading rights for all nations in China and to prevent any single power from monopolizing Chinese markets. It aimed to protect American commercial interests and maintain stability in the region. The policy was met with mixed reactions; while it was welcomed by some nations seeking access to Chinese markets, it faced resistance from other powers that sought greater control over China, leading to tensions and conflicts, including the Boxer Rebellion. Ultimately, the Open Door Policy laid the groundwork for America's future involvement in Asian affairs.
