The London conference was marred by a dispute between the Soviet Union and the United States over occupation of Japan and little of substance was accomplished. The Moscow conference was more productive; it agreed to the preparation of peace treaties with Italy, Romania, Bulgaria, Hungary and Finland; the creation of an eleven–member Far Eastern Commission and a four–member Allied Council for Japan. It also agreed to the establishment by the United Nations of a commission for the control of atomic energy, as well as a number of other lesser issues brought about by the end of World War II.
