The Open Door Policy

The open-door policy was a major statement of the United States for a foreign policy issued in 1899-1900 intended to protect the rights of all countries to trade equally with China and confirming multi-national acknowledgment of China's administrative and territorial sovereignty. Proposed by the U. S. secretary of state John Hay and supported by president William McKinley, the open door policy formed the foundation of U. S. foreign policy in East Asia for more than 40 years.

The Open Door Policy is a term in foreign affairs initially used to refer to the United States policy established in the late 19th century and the early 20th century that would allow for a system of trade in China open to all countries equally. It was used mainly to mediate the competing interests of different colonial powers in China.
