Bangladesh, Bhutan, India, Nepal (BBIN) Initiative The Bangladesh, Bhutan, India, Nepal (BBIN) Initiative is a sub-regional coordinative architecture of countries in South Asia. It operates through Joint Working Groups (JWG) comprising official representation from each member state that meet for consultative discussions on formulation, implementation and review of quadrilateral agreements. Areas of joint cooperation have included water resources management, integration and connectivity of power grids, multi-modal transport, cargo transit and trade infrastructure.  Background The group was formed after informal meetings that gradually developed into a consensus towards the need for sub regional connectivity beyond bilateral agreements. It was given greater impetus following the failure of other regional cooperation mechanisms to deliver substantial change in trade, power and infrastructural linkages.  The November 2014 SAARC summit held at Kathmandu saw widespread approval of a proposed land transport connectivity agreement by regional states, apart from the reservations of one country which caused the accord to fall through. However, the Summit Declaration encouraged sub regional initiatives in the effort to strive for greater regional connectivity. A framework for cooperation between four regional countries was subsequently realized. Framework Through the regular meeting of Joint Working Groups, representatives of the four nations explore avenues of further cooperation, exchange experiences, views and best practices across across several sectors, review data sharing arrangements for disaster mitigation and environmental forecasting, as well as strengthen measures to facilitate transit such as shared border stations on important routes and harmonized customs procedures. The priority for member states has been identified as "connectivity", encompassing electricity, shared access by and to road, rail, air and port infrastructure, and ease of travel. To this end, a sub regional Motor Vehicle Agreement allows buses and eventually private vehicles with a BBIN permit to travel freely without border impediments between the four countries. Although such initiatives further augment trade ties and commerce between the sub regional countries, the importance accorded to the architecture as an alternative to others, in a region considered amongst the least integrated in the world,has been interpreted as bearing significant political and strategic undertones.

Meetings of Joint Working Groups The next session of JWG presided over by Ministers of Transport is tentatively scheduled for June 15, 2015, for signing of the Bangladesh, Bhutan, India and Nepal (BBIN) Motor Vehicle Agreement for the Regulation of Passenger, Personal and Cargo Vehicular Traffic.
