Representatives explore avenues of cooperation, exchange experiences and best practices, review data-sharing arrangements for disaster forecasting and mitigation, and strengthen transit facilitation measures such as shared border stations on key routes and harmonised customs procedures through regular JWG sessions. The emphasis on "connectivity" also includes shared access to road, rail, air, and port facilities, as well as ease of travel. To that purpose, a subregional motor vehicle agreement approved in Thimphu would allow buses and eventually private automobiles with BBIN licences to drive freely across borders. Although clearly for commercial purposes, the diplomatic weight afforded to this arrangement over alternatives in an area regarded as the least connected was perceived to imply a purpose beyond intertwined business.
