Concept note-1: -The Open Door Policy was a policy between China, the US, Japan, and several European powers that stated each of those countries should have equal access to Chinese trade. It was created in 1899 by US Secretary of State John Hay and lasted until 1949, when the Chinese civil war ended.
Concept note-2: -What was the Open Door policy? The Open Door policy was a statement of principles initiated by the United States in 1899 and 1900. It called for protection of equal privileges for all countries trading with China and for the support of Chinese territorial and administrative integrity.
Concept note-3: -Hay argued that establishing equal access to commerce would benefit American traders and the U.S. economy, and hoped that the Open Door would also prevent disputes between the powers operating in China.
Concept note-4: -U.S. Relations with China in the Age of Imperialism So, the U.S. supported an “Open Door” policy, which meant that China would have an “open door” to foreign investment and trade, but no nation would control it.
Concept note-5: -The United States established the Open Door Policy because it wanted to make sure it had access to Chinese markets and resources. By the late-1890s it appeared that China was about to be partitioned up among European powers as Africa had before it.
