Yes they know what China ask from India and how it is going to behave. It is not just advantge for US to have this deal but much more for India. Mr. Singh is an economist and also a patriot. Deal will decide the future of how much west can trust India.I do not say deal under the pressure. Did China think of us when doing deal with US in the past. Are we not neighbour.Still that is okay but when is China claim going to stop on Indian terriotory then equipping the rebels groups and terrorrist if needed. If it does not think of India but just its benefit then should India not be so strong to protect itself and have US too on its side.
