You mean like FDR did at Yalta?
There was agreement that the priority was the unconditional surrender of Nazi Germany. After the war, the country would be split into four occupied zones, with a quadripartite occupation of Berlin as well. Stalin agreed to let France get the fourth occupation zone in Germany and Austria, carved out from the British and American zones. France would also be granted a seat in the Allied Control Council.
Poland which the Nazis invaded and which started the war was handed over by FDR to Stalin:The status of Poland was discussed but was complicated by the fact that Poland by this time was under the control of the Red Army. It was agreed to reorganize the Provisionary Polish Government that had been set up by the Red Army through the inclusion of other groups as the Polish Provisional Government of National Unity to be followed by democratic elections. (This effectively excluded the exile Polish government that had formed in London).
