Why has India become the world's top arms buyer?:

 "India has replaced China as the world's largest arms buyer, accounting for 10 per cent of all arms purchases during the past five years, a Swedish research group said. India purchased some $12.7 billion in arms, 80 per cent of that from Russia, during 2007-2011, according to the Stockholm International Peace Research Institute (SIPRI). China's arms purchases during that time were $6.3 billion, 78 per cent of which came from Russia.

 India has tried, but failed, to create a sizable domestic manufacturing industry for weapons or even basic military goods, while China has increased production of defence supplies. About 75 per cent of India's weapons purchases came from imports during 2007-11, said Laxman Kumar Behra of the Institute of Defense Studies and Analysis, a government-funded research organisation."
