France and the USSR were allies before World War 2. A number of things intervened before then and 1945, not limited to the war itself. After the war, did Soviet officials publicly (or privately) acknowledge France as closer to them diplomatically than its neighbours?
The treaty you refer to was largely meaningless. Only the German propaganda machine was perverse enough to call the relationship it established an "alliance".
France never forgave the humiliation of having been liberated - and France worked hard to show its independence from the British and Americans, culminating in leaving the NATO military organization - de Gaulle was immediately invited to the SU and toured it extensively, using every opportunity to condemn the US.
These "special relationships" included sending a Frenchman to a Soviet space station (the only westerner to go on a Soviet rocket during the cold war) and ascribing a disproportional role to the French WW2 efforts in the Soviet propaganda (including secondary school history program).
