See, I this doesnt have anything to do with Pakistan being a gate for China, What nawaz is dreaming about is a whole city designed around a yet to be operational port and making it a duty free trading and commerce hub.
See the location one more time and see the assess the potential one more time. You are not surrounded by trillion dollar economies that are trading, commercial and industrial power houses............. except china who have major trading in the far east, central asia, europe, africa and the americas and none of those pass through gwadar. as for middle east trading they already have established hubs there....for eg Dubai.
If its for transit of oil and gas - letss see how feasible it is...IP failed to take off.
