No, there were negotiations for the reunification of Germany and during those a few Western officals offered not to go further east. However that ended up not being part of the final treaties. In fact the 2+4 Treaty, which the Soviets signed does clearly state that ALL of Germany is part of NATO, with NATO troops being allowed to be stationed in former East Germany as well. Obviously that is just Germany, but in no other country, did the Soviets have any sort of legal reason to deny joing NATO what sort ever.
So no this is just Russian propaganda and not to be taken seriously.
