At Yalta, Roosevelt and Churchill discussed with Stalin the conditions under which the Soviet Union would enter the war against Japan and all three agreed that, in exchange for potentially crucial Soviet participation in the Pacific theater, the Soviets would be granted a sphere of influence in Manchuria following Japan's surrender. This included the southern portion of Sakhalin, a lease at Port Arthur (now Lüshunkou), a share in the operation of the Manchurian railroads, and the Kurile Islands.
Roosevelt, Churchill, and Stalin agreed not only to include France in the postwar governing of Germany, but also that Germany should assume some, but not all, responsibility for reparations following the war.
The Americans and the British generally agreed that future governments of the Eastern European nations bordering the Soviet Union should be "friendly" to the Soviet regime while the Soviets pledged to allow free elections in all territories liberated from Nazi Germany.
Negotiators also released a declaration on Poland, providing for the inclusion of Communists in the postwar national government.
All parties agreed to an American plan concerning voting procedures in the Security Council, which had been expanded to five permanent members following the inclusion of France. Each of these permanent members was to hold a veto on decisions before the Security Council.
