At the Yalta Conference, France was granted an occupation zone within Germany. France was a participant in the Berlin Declaration and was to be an equal member of the Allied Control Council. Nevertheless, at the insistence of the Americans, Charles de Gaulle was not invited to Potsdam, just as he had been denied representation at Yalta. The diplomatic slight was a cause of deep and lasting resentment for him. Reasons for the omission included the longstanding personal mutual antagonism between Roosevelt and de Gaulle, ongoing disputes over the French and American occupation zones, and anticipated conflicts of interest over French Indochina. It also reflected the judgement of the British and the Americans that French aims, with respect to many items on the conference's agenda, were likely to contradict agreed-upon Anglo-American objectives.
