Four-Power Treaty
The Four-Power Treaty was a treaty signed by the United States, United Kingdom, France and Japan at the Washington Naval Conference on 13 December 1921. It was partly a follow-on to the Lansing-Ishii Treaty, signed between the U.S. and Japan.
By the Four-Power Treaty, all parties agreed to maintain the status quo in the Pacific, by respecting the Pacific territories of the other countries signing the agreement, not seeking further territorial expansion, and mutual consultation with each other in the event of a dispute over territorial possessions. However, the main result of the Four-Power Treaty was the termination of the Anglo-Japanese Alliance of 1902.
