India-Sri Lanka Sign 3 Defence MoUs: Rajnath Singh's Historic Colombo Visit, L70 Anti-Aircraft Guns, and Neighbourhood First Policy

Why in News

Defence Minister Rajnath Singh visited Colombo, Sri Lanka, in early September 2026 — marking the first visit by an Indian Defence Minister to Sri Lanka in 38 years. During the visit, India and Sri Lanka signed three defence Memoranda of Understanding (MoUs), covering anti-aircraft gun upgrades, defence college cooperation, and the National Cadet Corps (NCC) Youth Exchange Programme.

Background

India and Sri Lanka share a maritime boundary of approximately 65 km at the narrowest point (Palk Strait) and a historically layered relationship encompassing ethnic ties, trade, and strategic proximity. Sri Lanka is central to India's Neighbourhood First Policy and its SAGAR (Security and Growth for All in the Region) vision.

• 2022 Sri Lanka economic crisis: Sri Lanka faced its worst economic crisis since independence, with foreign exchange reserves depleting to near-zero, causing fuel, medicine, and food shortages. India extended a credit line of over USD 4 billion (lines of credit, currency swaps, humanitarian assistance) — the largest single-country support Sri Lanka received during the crisis.
• China factor: China's infrastructure investments in Sri Lanka (Hambantota Port, Colombo Port City) and intelligence-gathering concerns (Chinese research vessels docking at Sri Lankan ports) have heightened India's strategic interest in deepening Sri Lanka's defence alignment.
• Post-Aragalaya politics: Following the mass protests (Aragalaya) that ousted President Gotabaya Rajapaksa in 2022, Sri Lanka elected Anura Kumara Dissanayake (AKD) as President in September 2024 — a historically Left-leaning leader who has recalibrated Sri Lanka's foreign policy toward a more balanced position between India and China.
• Previous Indian Defence Minister visit to Sri Lanka was George Fernandes in 1988 — 38 years ago — underscoring the historic nature of this visit.

Current Developments — The Three MoUs

Rajnath Singh met Sri Lankan President Anura Kumara Dissanayake (who also holds the Defence portfolio), Prime Minister Harini Amarasuriya, the Defence Secretary, and commanders of Sri Lanka's three armed forces. The following MoUs were signed:

MoU 1: Upgradation of Six L70 Anti-Aircraft Guns

• India will fund the upgradation of six L70 anti-aircraft gun systems belonging to the Sri Lanka Air Force, under an Indian government grant
• The L70 is a Bofors-designed 40mm L/70 anti-aircraft artillery piece — a legacy system widely deployed across South Asia. Its upgrade enhances air defence coverage of critical Sri Lankan assets including airports and naval installations
• This strengthens Sri Lanka's ability to defend its airspace without relying on Chinese or Pakistani defence suppliers, which is strategically significant for India
• The grant modality (as opposed to credit line) reflects India's intent to use defence assistance as a relationship-building tool rather than purely commercial

MoU 2: National Defence College (NDC) Academic Cooperation

• Academic cooperation agreement between the National Defence College of India (NDC, New Delhi) and the National Defence College of Sri Lanka
• Facilitates faculty exchanges, curriculum sharing, joint research on regional security, and participation of Sri Lankan officers in NDC India's prestigious one-year course
• NDC India's alumni include future service chiefs and senior bureaucrats — participation builds lasting institutional linkages at the highest military-civilian levels

MoU 3: NCC Youth Exchange Programme

• Formalises and expands the National Cadet Corps (NCC) Youth Exchange Programme between India and Sri Lanka
• Allows youth cadets from both countries to visit each other's NCC training facilities, participate in joint camps, and build people-to-people ties at the next generation of leadership
• The NCC (National Cadet Corps, India) operates under the Ministry of Defence and is governed by the NCC Act, 1948

Key Facts

Constitutional Provisions

• Article 51 — Directive Principle: State shall promote international peace and maintain just and honourable relations between nations
• Article 246 read with Schedule VII, List I, Entry 14 — Entering into treaties and agreements with foreign countries and their implementation — Union's exclusive competence
• Article 73 — Executive power of the Union extends to matters on which Parliament has power to make laws, which includes defence and foreign affairs

Legal Framework

• NCC Act, 1948 — establishes the National Cadet Corps; enables cross-border exchanges under executive agreement
• Defence Cooperation Agreement between India and Sri Lanka — the umbrella framework under which the MoUs derive their authority
• Vienna Convention on the Law of Treaties (1969) — under which MoUs, as non-legally-binding instruments, operate; India and Sri Lanka are both parties

Institutional Framework

• Ministry of Defence, India — coordinates and authorises bilateral defence cooperation
• National Defence College, New Delhi — premier joint services and civilian leadership institution, training future service chiefs and IAS officers at the senior-most levels
• National Cadet Corps (NCC) — tri-service youth organisation under the Ministry of Defence; promotes discipline, leadership and national integration
• Sri Lanka Air Force — the aerial branch operating the L70 anti-aircraft systems to be upgraded
• SAARC (South Asian Association for Regional Cooperation) — the regional multilateral body of which both India and Sri Lanka are members, though SAARC has been largely dormant since 2016
• Indian Ocean Rim Association (IORA) — India and Sri Lanka are both members; maritime cooperation is coordinated partly through this body

Economic Dimensions

India-Sri Lanka bilateral trade was approximately USD 5 billion in 2024-25, with India being Sri Lanka's largest trading partner. India's USD 4 billion+ support during the 2022 crisis included RBI currency swaps, petroleum credit lines, and humanitarian assistance that prevented total economic collapse.

The India-Sri Lanka Free Trade Agreement (ISFTA, 2000) remains in force, but negotiations for a comprehensive economic partnership (CEPA) have been stalled. The defence MoUs are part of a broader package to revitalise the relationship alongside economic ties.

For Banking angle: India extended a USD 400 million currency swap to Sri Lanka during the crisis under the SAARC Currency Swap Framework, which the RBI administers. RBI's currency swap mechanisms with neighbours are relevant for NABARD and banking awareness sections.

International Relations

Sri Lanka's strategic location — at the crossroads of Indian Ocean shipping lanes, 65 km from India's southern coast — makes it critical to India's maritime security:

• China's Hambantota Port (99-year lease, 2017): Sri Lanka leased Hambantota Port to China Merchants Port Holdings for 70 years on debt equity conversion — widely cited as a "debt trap diplomacy" case study. Indian strategic anxiety about Chinese naval presence near its southern shores is a primary driver of the deepened defence engagement
• Chinese research vessel controversy: In 2023, Sri Lanka initially permitted but later (under Indian pressure) restricted Chinese research/spy ships from docking — illustrating India's leverage over Sri Lanka's foreign policy choices
• Neighbourhood First Policy: India's foreign policy doctrine of prioritising immediate neighbours — Bangladesh, Nepal, Bhutan, Sri Lanka, Maldives, Pakistan — in development assistance, connectivity, and people-to-people ties
• SAGAR vision: PM Modi's 2015 maritime initiative "Security and Growth for All in the Region" — positions India as a net security provider in the Indian Ocean, countering China's growing naval presence

Challenges

• Ethnic Tamil question: The 13th Amendment to Sri Lanka's Constitution (1987, also known as the Rajiv Gandhi-Jayawardene Accord outcome) mandated devolution to provincial councils — India continues to press Sri Lanka for full implementation; Tamil Nadu's political sensitivity on this issue complicates bilateral relations
• Fishermen dispute: Indian fishermen from Tamil Nadu fishing in Palk Bay waters claimed by Sri Lanka are periodically arrested — a recurring irritant
• Debt restructuring and Chinese influence: Sri Lanka's debt restructuring negotiations (ISB holders, China, India) have complex geopolitical dimensions; any alignment too close to India risks backlash from Sri Lanka's domestic constituency wary of big-brother perceptions
• AKD's political base: President Dissanayake's NPP/JVP base has historically been wary of excessive alignment with India; balancing Indian and Chinese relationships will remain a tightrope

Government Initiatives

• India-Sri Lanka Economic Partnership Vision 2030 — framework for deepening economic ties post-crisis
• Connectivity projects: India-Sri Lanka power grid interconnection study; ferry services between Nagapattinam and Kankesanthurai; Trincomalee tank farm redevelopment
• Debt relief: India provided debt restructuring assurances to Sri Lanka ahead of IMF program negotiations in 2023
• Grant assistance: India's Defence Ministry has provided coast guard vessels, patrol boats, and now the L70 upgrade grant — building capacity without dependency

Way Forward

The NITI Aayog's India@2047 vision and the Economic Survey have emphasised India's role as a regional anchor economy. For India-Sri Lanka, the path forward per strategic think tanks like ORF and IDSA includes:

• Concluding the stalled Economic and Technology Cooperation Agreement (ETCA) to replace the narrower ISFTA
• Finalising the India-Sri Lanka maritime boundary demarcation and the Palk Bay fishermen agreement on zones of operation
• Full implementation of the 13th Amendment to Sri Lanka's Constitution for provincial devolution — India's long-standing ask
• Establishing a Joint Working Group on Maritime Security to coordinate responses to narcotics trafficking, smuggling, and non-traditional threats

FAQ

What are the 3 defence MoUs signed between India and Sri Lanka in September 2026?

1) Upgradation of six L70 anti-aircraft guns of Sri Lanka Air Force under Indian grant; 2) Academic cooperation between NDC India and NDC Sri Lanka; 3) NCC Youth Exchange Programme between India and Sri Lanka.

Why is Rajnath Singh's Sri Lanka visit historically significant?

It is the first visit by an Indian Defence Minister to Sri Lanka in 38 years — the last was George Fernandes in 1988. It signals India's intent to deepen defence ties at the highest level.

What is India's Neighbourhood First Policy?

Launched under PM Modi in 2014, it is a foreign policy doctrine that prioritises India's immediate neighbours — Bangladesh, Nepal, Bhutan, Sri Lanka, Maldives, and Pakistan — for development assistance, connectivity infrastructure, and people-to-people ties.

What is the significance of L70 anti-aircraft guns in this MoU?

The L70 is a Bofors-designed 40mm anti-aircraft artillery system. Upgrading these for the Sri Lanka Air Force under an Indian grant strengthens Sri Lanka's air defence without relying on China or Pakistan, which is strategically significant for India given Sri Lanka's location in the Indian Ocean.
