Bhutan was unable to obtain public and parliamentary approval of the agreement. The country`s parliament has expressed environmental concerns in order to cripple the deal. „On the traditional route, the vehicles covered 1550 km. So you can very well imagine the time and money savings that will result from the BBIN agreement,” he told reporters who displayed the flag of the Secretariat of State (Nabanna). The agreement will enter into force after being ratified by the four Member States. The agreement has been ratified by Bangladesh, India and Nepal. The lower house of the Bhutanese parliament approved the deal in early 2016, but it was rejected by the upper house in November 2016.  Bhutan has requested a cap on the number of vehicles entering its territory.  In May 2017, the media reported that the Bhutanese government had ordered the Indian government to continue the agreement without Bhutan because the Bhutanese government could not ratify the agreement in the upper house due to objections from opposition parties.  Opponents of the measure in Bhutan claimed that the agreement would increase vehicle traffic from other countries, which would affect Bhutanese truck drivers and also cause environmental damage. An existing bilateral agreement between Bhutan and India already allows for smooth car traffic between the two countries. Therefore, Bhutan`s decision not to ratify the BBIN MVA would only affect its trade with Nepal and Bangladesh. The Bhutanese government called on other BBIN members to continue with the agreement and also said it would try to ratify the MVA after the country`s parliamentary elections in 2018.
Due to tense relations between Bhutan and Nepal, the government led by Tshering Tobgay feared that the entry of Nepalese trucks into Bhutan would anger the electorate.  India described Bhutan`s decision as a „setback” rather than a „rejection” of the agreement, stating that it was natural that not all members could move at the same pace and that India continue its engagement with Bhutan on this issue.   From now on, the cargo vehicle will be tracked electronically and permits have been issued online and sent electronically to all land ports. It also includes an electronic seal that alerts controllers whenever the container door is opened. The Bangladesh, Bhutan, India, Nepal Initiative (BBIN) is a sub-regional architecture of countries in East South Asia, a sub-region of South Asia. It meets through the official representation of Member States to formulate, implement and revise quadrilateral agreements in areas such as water resources management, energy connectivity, transport and infrastructure.  The government will initially grant BBIN approval to commercial buses, while private vehicles will be allowed to use this option later. BBIN countries will benefit from reciprocal cross-border transport of passengers and goods, which promotes safe and environmentally friendly road transport in all countries, while supporting the economic development of the region, which remains one of the least connected parts in terms of physical connectivity. A proposal to sign an agreement on motor vehicles was initially adopted at the South Asian Association for Regional Cooperation (SAARC) summit in Kathmandu in November 2014. According to one report, the agreement was not signed at the time due to Pakistan`s reservations. The BBIN States then decided to continue the initiative without the participation of Pakistan.
(Id.) Although India and Bangladesh have already entered into a vehicle transport agreement, authorities have prevented vehicles from crossing the border for more than 93 miles (150 km). Carriers who wanted to ship goods beyond 93 miles from the border had to transfer the goods to another vehicle to complete the journey. At regular JWG meetings, representatives explore opportunities for cooperation, exchange experiences and good practices, discuss data exchange modalities for disaster prediction and mitigation, and strengthen transit facilitation measures such as common border posts on key routes and harmonized customs procedures.  The priority of „connectivity” continues to include seamless power grids, shared access to road, rail, air and port infrastructure, and ease of travel. To this end, a sub-regional motor vehicle agreement approved in Thimphu would allow buses and later private vehicles with a BBIN permit to travel unhindered against border barriers.   Although these are clearly economic intentions, the diplomatic weight given to this structure, as opposed to alternatives in a region considered the least integrated, has been seen as a meaning that goes beyond intertwined trade.  Each member of the BBIN Group bears its own costs for the implementation of the Agreement and sets certain fees for the entry of vehicles from another country into its territory. The agreement also allows for the inspection and search of the transit vehicle. The BBIN Motor Vehicle Agreement is very similar to saARC`s motor vehicle design, but is subject to minor changes. The much-discussed SAARC agreement of 2014 could not be signed after one of the countries of the subcontinent expressed reservations on the free movement of goods. In addition, there are problems with freight insurance, as any vehicle that travels to the territory of another country should have a comprehensive insurance policy. At present, such a policy of one country is not recognized in another country among the parties to the agreement.
According to Vijay Chhibber, the Union`s Secretary for Road Transport and Motorways, the cargo vehicle will travel a distance of 640 km (about 640 km) from Kolkata (West Bengal) to Dhaka (Bangladesh) and finally to Agartala (Tripura). In December 2018, Bhutanese Foreign Minister Tandi Dorji said the new government would reconsider the motor vehicle deal, noting that Bhutanese trucks were struggling to enter Bangladesh, while trucks from India and Nepal had easy access.  During the second Federal Foreign Office (FOC) consultations between Bangladesh and Bhutan in Dhaka in March 2019, Bangladeshi Foreign Minister Shahidul Haque stressed the importance for Bhutan to ratify the agreement, calling it „crucial” for the future development of the region.  They met last week in New Delhi to discuss the draft Memorandum of Understanding between Bangladesh, India and Nepal on the implementation of the BBIN MVA without obligation to Bhutan. This will usher in a new era of neighbourhood cooperation in this subregion. They reaffirmed their understanding that BBIN MVA protects the rights and obligations of all parties under other international and bilateral agreements within the Group. B2B Cargo itineraries are not included in BBIN. Transhipment will remain the most cost-effective mode of transport. because most vehicles come back empty. The BBIN routes are asymmetrically favorable to India, which connects the India-BD-India routes. For others, the volume of regional transit traffic is insignificant and existing modes of transport will remain the most cost-effective option. In June 2015, Bangladesh, Bhutan, India and Nepal (BBIN) concluded the landmark transport agreement that would allow motor vehicles to easily transport people and goods across any country.
This would negate decades of frustration for companies engaged in land trade between BBIN countries. In addition, the Auto Pact will enable the creation and expansion of the region`s rubber, bamboo and food industries. India proposed an agreement on SAARC motor vehicles at the 18th SAARC Summit in Kathmandu in November 2014. Due to Pakistan`s objections, no agreement could be reached. Instead, India has a similar motor vehicle agreement with BBIN. The BBIN Motor Vehicle Agreement (MVA) was signed on 15 June 2015 at the BBIN Transport Ministers` Meeting in Thimpu, Bhutan.   The Agreement will allow Member States to use their vehicles on the territory of other Member States for the carriage of goods and passengers, including the carriage of third countries and passenger cars. Each vehicle would require electronic authorization to enter the territory of another country, and the border security agreement between the nations` borders would also remain in place.
 Trucks can enter any of the four countries without having to reload goods from one country to another at the border. As part of the system, cargo vehicles are tracked electronically, permits are issued online and sent electronically to all land ports. .
