India was pretty pro-Soviet Union during the cold war. More than any other non socialist country, except maybe Nasserist Egypt. The non aligned movement was that in name only.Not surprising. India was always like that "playing between east and west", trying to be favored by USSR and USA at the same time since its foundation. Everybody knows that.
I don't think it's a wise strategy for India to be trying to play both sides. They are allowed to buy cheap oil but have had to give up all new military deals with Russia.
