You don't know real situation.
Bangladesh has built tons of new roads/ports for helping two way trade while Indian states like Assam are sitting on their hands. No money allocated even for container barges.
Bangladesh has standardized river container carriers (176 TEUs) and all ships plying between Kolkata and Dhaka are Bangladeshi vessels.
Show me any evidence of actual infra in India for anything you claim. NOTHING has been done on Indian side. NOTHING.
Taking a small barge with ten containers from Kolkata to Assam via Bangladesh and unloading them at a dirt riverbank there does not mean jack.
Meanwhile this is what Bangladesh did for a river container port. We have inland container port situation near Dhaka and building more of them now.
Those MOU's with Bangladesh govt. are just promises for show - just to placate the media back in India.
Hasina just throwing Jaishankar some consolation prize "bones".
Shringla actually did a far better job and he was HC to Bangladesh for many years.
I don't know why Modi picked this guy instead of Shringla who was the actual "Bangladesh-hand" in the South block.
