The BBIN-MVA agreement identified a total of 30 priority transport connectivity projects, with a total estimated cost of more than $8 billion. These priority projects are expected to clean up and enhance the remaining parts of the trade and transport corridors in the four countries. The corridors and routes associated with them have been determined on the basis of analysis of regional and international trade models. This transformation of transport corridors into economic corridors could increase intra-regional trade by nearly 60% in South Asia and by more than 30% with the rest of the world. In June 2015, the transport ministers of Bangladesh, Bhutan, India and Nepal (BBIN) met in Thimphu, Bhutan, to discuss the sub-regional Motor Vehicle Agreement (MVA). In addition to Bhutan, the other three countries have ratified the agreement. Bhutan is in the process of completing its internal ratification process to allay concerns expressed by national stakeholders. However, Bhutan also announced that it could not ratify BBIN-MVA at this time and asked the other parties concerned to conduct the agreement without it. Bhutan fears vehicle pollution and environmental degradation if trucks from neighbouring countries have access to its territories. On the other hand, Nepal and Bangladesh insist that the agreement be implemented quickly.
However, Bangladesh, Bhutan, Nepal and India understood the importance of this vehicle agreement. That is why they quickly began negotiations among themselves on several joint working groups. India has turned to Bangladesh and Nepal through diplomatic channels to develop the modalities of the implementation of the MVA between Bangladesh, India and Nepal. BBIN-MVA is considered essential to the diversification of Nepal`s and Bangladesh`s commercial economy. At the 18th OSCE Summit in Kathmandu in November 2014, India proposed an agreement on SAARC motor vehicles. Pakistan`s objections failed to reach an agreement. Instead, India followed a similar agreement with BBIN. The BBIN Motor Vehicles Agreement (MVA) was signed on 15 June 2015 at the BBIN Transport Ministers` Meeting in Thimpu, Bhutan.   The agreement will allow Member States to transport their vehicles on the territory of the other cargo and passenger provider, including transport and passenger vehicles from third countries. Any vehicle would require electronic authorization to enter another country`s territory and border security agreements between the borders of nations are maintained.
 Freight vehicles can enter each of the four nations without the need to transfer goods from one country to another at the border. Under the system, cargo vehicles are electronically tracked, authorizations are issued online and sent electronically to all land ports. Vehicles are equipped with an electronic seal that alerts regulators every time the container door is opened.  At the 18th Summit of the South Asian Regional Cooperation Association (SAARC) in Kathmandu in 2014, the Heads of State and Government expressed for the first time their firm determination to „deepen regional integration for peace, stability and prosperity in South Asia, including by strengthening cooperation in the areas of trade investments, finance, energy, security, infrastructure, connectivity and culture; Implement priority projects, programs and activities, based on results and time.“ However, due to the political problems faced by ASARC member countries, the agreement ran into several difficulties and the idea was quickly abandoned. In addition, there are freight insurance problems, as any vehicle operating in another country should have full insurance. At present, such a country`s policy is not recognized by the parties to the agreement in another country. A meeting of officials in New Delhi discussed passengers and freight protocols, which concluded the agreement to regulate passengers, passengers and freight transport between the four countries, which was signed in June 2015, said the
