because India is not the underdog in India-Pak scenario. India can do without Chinese weapons and India has an option, it can buy from any seller in the world.
and India can buy the original from Russia at almost same price. Why buy duplicate??
lol: Jokin. But yes, China just modifies Russian goods and sell, so its better to go for Russian.
Pak, Iran, North Korea, etc are countries which are a little isolated from the international arms market and they are the underdogs too. Thats the perfect recipe for China.
