It meets through official representation of member states to formulate, implement and review quadrilateral agreements across areas such as water resources management, connectivity of power, transport, and infrastructure.

[3] A Malé summit one year later agreed to co-ordinate efforts catered "to the special individual needs of three or more Member States,"[4] and formalised procedures focused on the subcontinent's north east to develop intra-regional trade and investment, tourism, communication, and energy resources.

[5] As the mechanism operated through specific projects, constituent members endeavoured to integrate without requiring alteration in broader policy or methods of governance.

Borders of member states rest within 50 kilometres of Siliguri, ergo contiguous norms, tradition and lifestyle amongst inhabitants underscore the importance of an integrated market.

[3] Considerable emphasis was placed upon power trading between naturally abundant and energy-scarce localities to address the impact of shortages on industrial production, reverse consequently depressed rates of growth, reduce transmission and distribution losses through interconnected grids, and provide needed revenue for upstream nations with adverse balance of payments.

Informal discussions led to renewed consensus on sub regional ties outside bilateral agreements, owing partly to continued failure of extant systems.

[7] A November 2014 Kathmandu summit saw endorsement of an accord on land transport by regional states, apart from one country's reservations causing it to fall through.

[10] The priority of "connectivity"[11] further embodies seamless electrical grids, shared access to road, rail, air and port infrastructure, and ease of travel.

[13][14] Although manifestly of economic intent, the diplomatic weight accorded to this structure as opposed to alternatives in a region considered least integrated,[15] was seen to connote purpose beyond interwoven commerce.

[35] Opponents of the measure in Bhutan claimed that the agreement would increase vehicular traffic from the other nations which would affect Bhutanese truckers and also cause environmental damage.

The Bhutanese government requested the other BBIN members to proceed with the agreement and also clarified that it would attempt to ratify the MVA after the country held general elections in 2018.

"[42] Sanjeev Ahluwalia, an advisor at Observer Research Foundation, writes that BBIN, as a sub-region within BIMSTEC, should forge "an interparliamentary group to enlarge cooperation say in cross border energy trade, digital security, space applications and green technology."

"[43] Pradumna B Rana, a visiting associate professor at Nanyang Technological University, finds BBIN economic cooperation gaining "considerable traction".
