I don't understand the comparison here.
We were talking in context of Pakistan and India, you stated Pakistan would benefit from Chinese manufacturing. My comment was in context of "yes you will benefit but how much will you be able to buy en masse from them". I don't understand how the current manufacturing capacities of Russia and India vs China is relevant here.
We are talking about affording weapons, wartime manufacturing i.e. economies of scale and TOT here
In times of war you can't rely on a foreign power to ship you spare parts and readymade weapons. Thus you'll need TOT and inhouse production.
