The agreement, which was a communiqué, was not a peace treaty between the peoples, although it created the fait accompli. It was replaced by the Treaty on the Definitive Regime, signed on 12 September 1990, in accordance with Germany. Truman was much more suspicious of the Soviets than Roosevelt and increasingly suspicious of Stalin`s intentions.  Truman and his advisers regarded Soviet action in Eastern Europe as aggressive expansionism, incompatible with the agreements Stalin had been obliged to in Yalta in February. In addition, Truman discovered possible complications elsewhere when Stalin rejected Stalin Churchill`s proposal to withdraw the Allies from Iran before the timetable agreed at the Tehran conference. The Potsdam conference was the only time Truman met Stalin himself.   In Potsdam, little real progress has been made, exceeding an agreement to fulfil the commitments made at Yalta. The Conference agreed on the creation of a Council of Foreign Ministers representing the five main powers, continuing the preliminary work essential for peace agreements and taking on other issues that could sometimes be entrusted to the Council, by mutual agreement between the governments concerned by the Council. The establishment of the Council in question did not contradict the agreement of the Crimean conference that there should be regular meetings between the foreign ministers of the three governments. After the text of the council agreement, it was decided:  The Potsdam Conference, held from 17 July to 2 August 1945 near Berlin, was the last of the three major meetings of the Second World War. The conference brought together the President of the Soviet Union, the new US President Harry S. Truman and the British Prime Minister Winston Churchill (replaced on 28 July by his successor Clement Attlee). On 26 July, the Heads of State and Government issued a statement calling for Japan`s “unconditional surrender” and hiding the fact that they had privately agreed to let Japan retain its emperor.
For the rest, the conference revolved around post-war Europe. A Council of Foreign Ministers, composed of the Big Three, China and France, was agreed. The german military administration was set up with a central allied supervisory board (the requirement that access decisions be unanimous would prove crippling at a later date). The heads of state and government have reached various agreements on the German economy, with a focus on the development of agriculture and non-military industry. The institutions that controlled the Nazi economy had to be decentralized, but all of Germany would be treated as a single economic entity. War criminals would be brought to justice. Stalin`s request to define the German-Polish border was pushed back to the peace treaty, but the conference accepted his transfer from the country east of the Oder and the Neisse from Germany to Poland. With regard to repairs, a compromise was drawn up on the basis of an exchange of capital equipment from the western zone for eastern raw materials. It resolved a dispute, but set a precedent for the management of the German economy by zone and not exhaustive, as the Western powers hoped. Although post-war Europe dominated Potsdam`s agenda, the war in the Pacific was on stage. Shortly after arriving in Potsdam, Truman received the news of the success of the atomic bomb test. He told Churchill the news, but mentioned “a new weapon” to Stalin.
