All three leaders ratified the agreement of the European Advisory Commission setting the boundaries of post-war occupation zones for Germany : three zones of occupation , one for each of the three principal Allies : The Soviet Union , the United Kingdom , and the United States . They also agreed to give France a zone of occupation , carved out of the US and UK zones ; although De Gaulle on principle subsequently refused to accept that the French zone would be defined by boundaries established in his absence , ordering French forces to occupy Stuttgart in addition ; only withdrawing when threatened with the suspension of essential American economic supplies . Churchill at Yalta then argued that the French would necessarily also need to be a full member of the proposed Allied Control Council for Germany . Stalin resisted this , until eventually Roosevelt backed Churchill 's position ; but Stalin still remained adamant that the French should not be admitted to full membership of the Allied Reparations Commission to be established in Moscow , only relenting at the Potsdam Conference
