104 years ago today, December 13, 1921 (November 15, 1921 in the lunar calendar), the four countries signed a naval treaty in Washington. On December 13, 1921, the Washington Conference concluded successfully, and the United States, Great Britain, France and Japan signed the Pacific Treaty. The four countries agreed to respect each other's ownership rights in the Pacific based on the League of Nations norms. The four-nation treaty gives the United States the privileges of the League of Nations in the Pacific, despite its refusal to become a member of the world body. The United States will be able to conduct trade in the Pacific occupied by three other countries, and it will also be able to use important telegraph lines and telephone centers in the Yap Islands administered by Japan.
