Deng Xioaping didn't go to the USA to invite USA businesses to invest in China, in the very early eighties. No, what he did was change the rules and laws in selective parts of China SEZ, where foreign and Chinese companies were given free reign to do their businesses, exclusively focused on exports.
Modi can promote India all he likes, but unless the FUNDAMENTAL anti-business climate in India is changed, his begging and urgings in the USA will come to naught.
Deng was in charge of a totalitarian state, with highly centralised rule, and a nation steeped in efficient bureaucracy.
India on the other hand............its Modi's skills of what he can do....in India.
