The new international organization was formulated and negotiated among the delegations from the Allied Big Four at the Dumbarton Oaks Conference from 21 September to 7 October 1944. Representatives from the United States and the United Kingdom met first with those from the Soviet Union and, in the following week, with representatives from the Republic of China. They agreed on proposals for the aims, structure and functioning of the new international organization. It took the conference at Yalta, plus further negotiations with Moscow, before all the issues were resolved.
