# Regional blocs II: SAARC, BIMSTEC, GCC, Mercosur

SAARC's paralysis, BIMSTEC's rise, the GCC's energy-security architecture and Mercosur's customs union explained with founding charters, dates and exam-ready contrasts.

## SAARC: structure and paralysis

The **South Asian Association for Regional Cooperation (SAARC)** was established by the **SAARC Charter signed at Dhaka on 8 December 1985** by seven founding members—Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. **Afghanistan** joined as the eighth member at the 14th Summit (New Delhi, 2007). The Secretariat is at **Kathmandu (established 1987)**. Article X(2) of the Charter mandates that decisions be taken **by unanimity** and explicitly excludes **bilateral and contentious issues** from deliberations—a design choice that has neutralised SAARC whenever India–Pakistan tensions surge.

Its economic instrument is the **South Asian Free Trade Area (SAFTA)**, signed at the 12th Islamabad Summit (2004) and operational from **1 January 2006**, succeeding the 1995 SAPTA. Intra-SAARC trade remains under **5% of members' total trade**—the lowest of any regional bloc—owing to sensitive lists, non-tariff barriers and the India–Pakistan rupture.

SAARC has been effectively **moribund since 2016**: the 19th Summit scheduled for **Islamabad (November 2016)** was cancelled after the **Uri attack (18 September 2016)**, when India, Bangladesh, Bhutan and Afghanistan withdrew. No summit has convened since the 18th (Kathmandu, 2014).

## BIMSTEC: the pivot away from Pakistan

The **Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC)** originated as **BIST-EC** by the **Bangkok Declaration of 6 June 1997**; Myanmar joined later in 1997 (BIMST-EC) and **Nepal and Bhutan acceded in 2004**, fixing seven members: Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka and Thailand. The **BIMSTEC Charter was adopted at the 5th Summit (Colombo, 2022)** and entered into force in 2024, giving the grouping legal personality for the first time. The Secretariat is at **Dhaka (2014)**.

BIMSTEC bridges **SAARC and ASEAN**, uniting the Bay of Bengal littoral and excluding Pakistan—hence India's deliberate elevation of it after 2016, symbolised by the **BIMSTEC Outreach Summit at Goa (2016)** held alongside the BRICS Summit. It anchors India's **Act East Policy** and **Neighbourhood First**. Its connectivity agenda includes the **Master Plan for Transport Connectivity (adopted 2022)** and the long-negotiated **BIMSTEC Free Trade Area Framework Agreement (2004)**, still not fully operational. Compared with SAARC, BIMSTEC's strength is functional cooperation in security, energy and disaster management; its weakness is institutional thinness and slow trade liberalisation.

The contrast candidates must internalise: SAARC is **geographically South Asian but politically deadlocked by the consensus and bilateral-exclusion rules**; BIMSTEC is **a sub-regional, sectoral, India-led workaround** that sidesteps the Pakistan veto and links the Indian Ocean to Southeast Asia.
