The Open Door policy—first initiated in 1899, with a follow-up missive in 1900—was significant in its attempt by the United States to establish an international protocol of equal privileges for all countries trading with China and to support China’s territorial and administrative integrity. The policy was a cornerstone of American foreign policy in East Asia until the mid-20th century.
