Why Is the West providing technology to India? Previously, we have seen that Europeans and Americans provided various technologies (high-speed rail[1], aerospace[2][3], microprocessor[4], etc.) to China to earn instantaneous money. Later what happened was, China did its own research on those techs, improved them and became a giant vendor.

Apparently, the same is being repeated in case of India. The USA and EU is giving India missile tech[5], nuclear tech[6], aircraft carrier tech[7], fighter jet tech[8], and so on. India is also making 100% sure that they obtain those techs by enforcing a so-called policy named: "Make in India"[9].   

My question is, Why Is the West providing technology to India even though there is an imminent danger to the West of India becoming a 2nd giant vendor?

I may hazard a small guess to this. India has a very young workforce in comparison to its Asian counterparts (China and Japan). We especially see this in the field of software design where it has an even lower median age of labour than USA. As we know the West gains a lot from brain drain and stands to gain even more from young innovative minds that India produces, we can assume this access to new technology will let India produce even more bright minds.

As for India becoming a large vendor. We can see China will be facing extreme labour shortages soon due to it's high aged labour force and extreme brain drain. This in turn has China to be predicted to fall as a large vendor in the global market (Or at least possible). If it does India can take its place, easing the instability of the market, and if it doesn't we have a new youth force with amazing work ethic gain from.

Also from an Economic view more vendors in the market is decentralizing, which can be seen as good or bad depending.

Hope this had something to gain.
