The rising power of Japan alarmed the United States and the European powers. In order not to be threatened, the United States invited 8 countries to attend a conference in Washington in 1921, and later signed the 'Four-Power Pact','Five-Power Pact' and 'Nine-Power Pact'. The main objectives of these were to stop the naval race and to maintain a new order in East Asia and in the Pacific region, so as to avoid international conflicts.

日本崛起为世界强国，令美国及欧洲列强大为震惊，为了免受威胁，美国遂於1921 年邀请其他8国出席华盛顿召开的会议，其后签订了《四国公约》、《五国公约》及《九国公约》，目的是停止海军军备竞赛、稳定东亚及太平洋的新秩序，以及避免国际间的衡突。
