The relations between two countries are decades long.Russia has been co-operative to us in difficult times when we were lacking good infratructure,technology etc.Russians have helped us in strategic sectors like defence, space,atomic energy etc.No doubt they also have gained a lot from this but every relation needs some base to develope.After disintegration of Soviet union and emergence of India as global power,it has become imperative on part of both the countries to strengthen their ties further negating the hegemonial attitude of US.After all a friend in need is a friend indeed.Long live Indo-Russian friendship!
