100$ billion investment even if it was from the mouth of Xi himself would be unbelievable.
Money is money no matter in whose hands. Its on only vast returns are expected
So far we have seen Modi speak, effects of his action will only be visible earliest at a decade from now, to justify investment of such a vast sum.
You are right, we are just talking about tens of billions right now..may it be Xi's visit or Japan visit or even the FDI and the FII that's come which has been around the 20's in billion. Implementation of the projects will take at least 5 years. This doesn't go far in the short term. What is needed is not such investments on visits but rather an overhaul of the investment atmosphere if we desire 100's of billions in investment, and creating that environment will take a decade.
