Sir, the entire globe is talking about this project, and I've done some research on it too. The actual participation in "One Belt, One Road" started about 3-4 years ago between the Chinese and the Pakistanis. Previously, the Chinese helped create a new port to allow for a secondary port in Pakistan.
In fact, the port was built but it was under Singapore or Dubai's port operations company's management. The Chinese took it over from one of those guys. Their hope was that they can use this port for resupply and fuel / overhaul of the Chinese navy ships. Nowhere in the entire previous history, had there ever been a discussion that there was a remote possibility of $ 50 billion worth of investments.
I bet you, if India and others had known about it back then (when the US was next door and the previous Dictator / General in Pakistan pissed us off a lot), I think you'd have seen some serious reaction towards this project, may be a direct small level confrontation that would've damaged this area.
It happened so quickly and so fast that India and other who dislike Pakistan (including the UAE, Iran, etc, due to this project), couldn't really understand how it could move so forward in such a short amount of time. So really, from the Chinese President visiting Pakistan and formalizing the funding in 2014, till today, the end of 2016, you have one of the largest projects in the modern history actually gone live!!!! There is a lot to be said about the speed and expedited everything that this project went through. So good for Pakistan that it happened that way. But it was conceived and phase I completed in the same 3 years. Just mind blowing speed of getting stuff done at the largest magnitude possible. Thanks
