About BBIN:

•   The BBIN agreement was signed in June 2015 in Thimphu, Bhutan to facilitate cross border movement of both passengers and cargo vehicles. Protocols to implement the agreement are being negotiated by the four countries for passengers and cargo vehicles separately.
•     This Motor Vehicles Agreement (MVA) is signed for the Regulation of Passenger, Personnel and Cargo Vehicular Traffic among the four South Asian neighbours.
•     The pact will allow seamless movement of passenger and cargo vehicles among the four countries.
•    Under the agreement, the “contracting parties” will allow cargo vehicles for inter-country cargo, including third country cargo and passenger vehicles or personal vehicles, to ply in the territory of another country “subject to the terms of the agreement”. All vehicles, however, will require a permit for plying through the other country.
•   India is in a bilateral motor vehicle agreement with Nepal and Bangladesh, but a multilateral pact would go a long way in boosting trade in the region.
