South Asian Association for Regional Cooperation in the context of "Regional integration"

Regional organizations (ROs) are international organizations (IOs) whose membership is limited to states within a single geographic region. They have been established to foster cooperation and political and economic integration or dialogue among states within a region. They vary from loose cooperation arrangements to formal regional integration. Since their formal emergence after the end of World War II, they have become increasingly numerous and influential, often working closely with other multilateral organizations such as the United Nations.

Examples of ROs include, amongst others, the African Union (AU), Association of Southeast Asian Nations (ASEAN), Arab League (AL), Arab Maghreb Union (AMU), Caribbean Community (CARICOM), Council of Europe (CoE), Eurasian Economic Union (EAEU), European Political Community (EPC), European Union (EU), South Asian Association for Regional Cooperation (SAARC), Shanghai Cooperation Organisation, Asian-African Legal Consultative Organization (AALCO), Union for the Mediterranean (UfM), Union of South American Nations (USAN).

The South Asian Free Trade Area (SAFTA) is a 2004 agreement that created a free-trade area of 1.6 billion people in Afghanistan, Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan and Sri Lanka with the vision of increasing economic cooperation and integration.

One of the major goals was to reduce customs duties of all traded goods to zero by 2016. SAFTA required the developing countries in South Asia (India, Pakistan and Sri Lanka) to bring their duties down to 20 per cent in the first phase of the two-year period ending in 2007. In the final five-year phase ending in 2012, the 20-percent duty was reduced to zero in a series of annual cuts. The least developed countries in the region had an additional three years to reduce tariffs to zero. India and Pakistan ratified the treaty in 2009, whereas Afghanistan, as the eighth member state of the SAARC, ratified the SAFTA protocol on 4 May 2011.

The countries of the Bay of Bengal include littoral and landlocked countries in South Asia and Southeast Asia that depend on the bay for maritime usage. Historically, the Bay of Bengal has been a highway of transport, trade, and cultural exchange between diverse peoples encompassing the Indian subcontinent, Indochinese peninsula, and Malay Archipelago. Today, the Bay of Bengal region is the convergence of two major geopolitical blocs- the Association of Southeast Asian Nations (ASEAN) and the South Asian Association for Regional Cooperation (SAARC). The Bay of Bengal Initiative for Multisectoral Technical and Economic Cooperation (BIMSTEC) promotes regional engagement in the area.

The Bay of Bengal countries are often categorized into a maritime subregion. The bay hosts vital shipping routes linking its littoral and landlocked hinterland with the Indian Ocean. Its sea bed is being explored and exploited for hydrocarbon reserves.

Kathmandu (Nepali: [ˌkaʈʰmaɳˈɖu]) is the capital and largest city of Nepal, situated in the central part of the country within the Kathmandu Valley. As per the 2021 Nepal census, it has a population of 845,767 residing in 105,649 households, with approximately 4 million people in the surrounding metropolitan area. The city stands at an elevation of 1,324 metres (4,344 ft) above sea level.

Recognized as one of the oldest continuously inhabited places in the world, Kathmandu's history dates back to the 2nd century AD. Historically known as the Nepal Mandala, the valley has been the cultural and political hub for the Newar people, a significant urban civilization in the Himalayan region. Kathmandu served as the royal capital of the Kingdom of Nepal and is home to numerous palaces, temples, and gardens reflecting its rich heritage. Since 1985, it has hosted the headquarters of the South Asian Association for Regional Cooperation (SAARC).

The Asia Cooperation Dialogue (ACD) is an intergovernmental organization created on 18 June 2002 to promote Asian cooperation at a continental level and to ensure coordination among different regional organizations such as the ASEAN, the Gulf Cooperation Council, the Eurasian Economic Union, the Shanghai Cooperation Organisation, and the SAARC. It is the first international organization to cover the whole of Asia. Its secretariat is in Kuwait City.

Eastern South Asia is a subregion of South Asia. It includes the countries of Bangladesh, Bhutan, India (specifically East India and Northeast India), and Nepal. Geographically, it lies between the Eastern Himalayas and the Bay of Bengal. Two of the world's largest rivers, the Ganges and the Brahmaputra, flow into the sea through Eastern South Asia. The region includes the world's highest mountainous terrain and the world's largest delta, and has a climate ranging from alpine and subalpine to subtropical and tropical. Since Nepal, Bhutan, and northeast India are landlocked, the coastlines of Bangladesh and East India serve as the principal gateways to the region.

With more than 441 million inhabitants, Eastern South Asia is home to 6% of the world's population and 25% of South Asia's population. The Bangladesh, Bhutan, India, Nepal Initiative promotes economic integration in the region. The four countries are members of the South Asian Association for Regional Cooperation and the Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation. Yunnan Province and the Tibet Autonomous Region of the People's Republic of China (PRC) and Myanmar are historically, economically, and culturally interdependent on Eastern South Asia. The Bangladesh–China–India–Myanmar Forum has established an economic corridor in the region.

The Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) is an international organization of seven South Asian and Southeast Asian nations, housing 1.73 billion people and having a combined gross domestic product of US$5.2 trillion (2023). The BIMSTEC member states – Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka, and Thailand – are among the countries dependent on the Bay of Bengal.

Fourteen priority sectors of cooperation have been identified and several BIMSTEC centers have been established to focus on those sectors. As of 2018, BIMSTEC free trade agreement is under negotiation, considered similar to SAARC.
