India and World Affairs

Geostrategic Position of India

India occupies one of the most strategically significant positions in the world. Situated at the crossroads of South Asia, Southeast Asia, Central Asia, and the Middle East, India commands the northern Indian Ocean, which carries approximately 80 percent of the world's oil trade and an enormous share of global container shipping. India's peninsular landmass juts southward into the Indian Ocean, flanked by the Arabian Sea to the west and the Bay of Bengal to the east, giving it the ability to monitor and potentially interdict the principal maritime trade routes connecting the Persian Gulf to East Asia and connecting Europe to the Asia-Pacific. India's land borders touch seven countries: Pakistan to the northwest, China to the north and northeast, Nepal and Bhutan in the Himalayan north, and Myanmar, Bangladesh, and (through the Chicken's Neck corridor) the broader northeastern region adjacent to all three. This continental-maritime dual character makes India simultaneously a land power with continental concerns (border disputes with China and Pakistan, regional primacy in South Asia) and a maritime power with oceanic interests spanning the Indian Ocean Region (IOR).

The Himalayan mountain wall along India's northern frontier, while a formidable physical barrier, has proven strategically permeable: the 1962 Sino-Indian War demonstrated that China could project military force through high-altitude Himalayan terrain, and the ongoing boundary dispute along the Line of Actual Control (LAC) across Ladakh, Uttarakhand, Himachal Pradesh, Sikkim, and Arunachal Pradesh keeps the northern frontier as the dominant preoccupation of Indian strategic planning. The northwestern frontier, historically the avenue of invasion of the subcontinent from Central Asia (Persians, Greeks, Kushans, Huns, Arabs, Turks, Mughals), remains sensitive given the unresolved Kashmir dispute with Pakistan and Pakistan's nuclear arsenal. India's northeastern frontier, sharing borders with Myanmar and Bangladesh and connected to the mainland by the narrow Siliguri Corridor, presents both connectivity challenges and strategic vulnerabilities.

Geopolitically, India's position gives it natural interests and leverage in multiple overlapping theatres: the Indian Ocean from the Gulf of Aden and the Persian Gulf through the Arabian Sea and Bay of Bengal to the Strait of Malacca; the South Asian neighbourhood encompassing the SAARC countries; the extended neighbourhood including Central Asia (through which India seeks connectivity to bypass Pakistan), the Gulf Cooperation Council countries (which host 9 million Indian workers and supply 80 percent of India's oil imports), Southeast Asia (with which India pursues the Act East Policy), and East Africa (which has significant Indian diaspora communities and is a theatre of Chinese infrastructure investment). India's strategic location and growing economic weight make it a sought-after partner for major powers including the United States, Russia, France, Japan, and Australia, enabling India to pursue a policy of strategic autonomy - maintaining independent decision-making while engaging with multiple partners - rather than formal alliance membership.

K.M. Panikkar, India's most influential early strategic thinker, argued in India and the Indian Ocean (1945) that India's security is fundamentally maritime: whoever controls the Indian Ocean controls India's lifelines of trade and communication. Panikkar advocated for India to develop naval power commensurate with its geographical position. This tradition has influenced India's gradual naval buildup: India now operates two aircraft carriers (INS Vikramaditya, a refurbished Soviet carrier, and INS Vikrant, India's first indigenously built aircraft carrier commissioned in 2022), nuclear-powered ballistic missile submarines (INS Arihant and INS Arighaat), a growing fleet of destroyers, frigates, and submarines, and maritime patrol aircraft. India's naval reach extends across the Indian Ocean, with logistics agreements enabling access to bases and facilities in Oman, Djibouti, Singapore, Madagascar, Seychelles, Mauritius, and Sri Lanka.

Maritime Boundaries and the Exclusive Economic Zone

India's maritime boundaries are governed by the United Nations Convention on the Law of the Sea (UNCLOS 1982), to which India is a signatory. Under UNCLOS, India exercises different degrees of jurisdiction over different maritime zones. The Territorial Sea extends 12 nautical miles (approximately 22 km) from the baseline (the low-water line along the coast), within which India has full sovereignty equivalent to land territory, subject to the right of innocent passage by foreign vessels. The Contiguous Zone extends from 12 to 24 nautical miles, within which India can exercise control to prevent and punish infringement of its customs, fiscal, immigration, and sanitary laws. The Exclusive Economic Zone (EEZ) extends 200 nautical miles from the baseline; within the EEZ, India has sovereign rights for the purpose of exploring and exploiting, conserving and managing the natural resources of the seabed, subsoil, and the superjacent waters, as well as jurisdiction over marine scientific research, artificial islands, and the protection of the marine environment. India does not have sovereignty over the EEZ (foreign vessels have freedom of navigation), but has exclusive resource rights. The Continental Shelf may extend beyond 200 nautical miles up to 350 nautical miles where the natural prolongation of the land territory extends that far; India has submitted claims to an Extended Continental Shelf beyond 200 nautical miles to the Commission on the Limits of the Continental Shelf (CLCS).

India's total EEZ covers approximately 2.02 million square kilometres (including the EEZ around the Andaman and Nicobar Islands in the Bay of Bengal and the Lakshadweep Islands in the Arabian Sea), one of the largest EEZs in the world. The EEZ encompasses significant petroleum and natural gas deposits (Bombay High, the KG basin offshore block, the Mahanadi basin), fishery resources supporting millions of fisherfolk along India's 7,517 km coastline, and potential for deep-sea mineral extraction (polymetallic nodules, cobalt-rich ferromanganese crusts) and Ocean Thermal Energy Conversion (OTEC). India has been granted Pioneer Investor status by the International Seabed Authority for exploration of polymetallic nodules in the Central Indian Ocean Basin, with exploration blocks allocated in an area of approximately 150,000 sq km.

Maritime boundary disputes exist with several neighbours. The Sir Creek dispute with Pakistan concerns an approximately 96 km tidal creek in the Rann of Kutch between Sindh (Pakistan) and Gujarat (India): the location of the boundary within or along the creek determines the EEZ boundary in the Arabian Sea, with implications for potential hydrocarbon resources. The boundary has not been formally delimited. India and Bangladesh delimited their maritime boundary in the Bay of Bengal through an international arbitration award by the Permanent Court of Arbitration in 2014 (Bangladesh-India Maritime Boundary Arbitration), the first such delimitation through binding arbitration for India, which resolved overlapping EEZ claims in the Bay of Bengal and awarded Bangladesh a larger maritime area than it had previously controlled. India and Sri Lanka share the Palk Strait and the Gulf of Mannar; the maritime boundary was delimited in 1974 and 1976, but the Katchatheevu island (ceded to Sri Lanka under the 1974 agreement) remains a politically sensitive issue in Tamil Nadu, affecting the fishing rights of Indian fishermen in the Palk Strait. The Andaman and Nicobar Islands' maritime boundaries approach the EEZs of Myanmar, Thailand, Indonesia, and Malaysia, with particular strategic significance at the northern entrance to the Strait of Malacca.

Indian Ocean Geopolitics

The Indian Ocean is the world's third-largest ocean (approximately 70.56 million sq km) and the most strategically significant in terms of energy trade, global supply chains, and major power competition. Approximately 80 percent of the world's seaborne oil passes through the Indian Ocean, predominantly from the Persian Gulf to East Asia and Europe. The Indian Ocean's critical chokepoints include: the Strait of Hormuz (approximately 21 million barrels of oil per day, 20 percent of global oil supply); the Strait of Bab-el-Mandeb or Mandeb Strait (linking the Red Sea to the Gulf of Aden, controlling access to the Suez Canal and European markets); the Strait of Malacca (handling approximately 25-30 percent of global trade and the primary shipping lane for East Asian economies); and the Mozambique Channel (an alternative route around Africa when Suez is unavailable). Any power that can project force at these chokepoints has enormous leverage over global energy supply and trade.

China's growing presence in the Indian Ocean has been the most significant geopolitical development of the past two decades for India's strategic environment. China's String of Pearls strategy (a term first used in a 2005 Booz Allen Hamilton report for the US Department of Defense) refers to the network of ports and maritime facilities that China has developed or supported across the Indian Ocean littoral: Gwadar (Pakistan, connected to Xinjiang via the China-Pakistan Economic Corridor), Hambantota (Sri Lanka, leased to a Chinese SOE for 99 years in 2017 after Sri Lanka was unable to service Chinese debt), Chittagong (Bangladesh, with Chinese infrastructure investment), Kyaukpyu (Myanmar, part of the China-Myanmar Economic Corridor), and Djibouti (China's first acknowledged overseas military base, since 2017). While Chinese officials describe these as purely commercial port investments under the Maritime Silk Road (the sea-based component of the Belt and Road Initiative), Indian strategists see a dual-use military-commercial pattern that could enable the PLAN (People's Liberation Army Navy) to establish a permanent presence in the Indian Ocean, encircling India from the Arabian Sea and the Bay of Bengal.

India has responded to China's Indian Ocean presence through several strategies: naval expansion (aircraft carriers, nuclear submarines, expanded surface fleet); logistics exchange agreements with key Indian Ocean partners (the Logistics Exchange Memorandum of Agreement with the United States, access-and-services agreements with France, Australia, Japan, and island states); island territory development (the strategic development of Agalega Island in Mauritius, Assumption Island in Seychelles, and infrastructure in the Andaman and Nicobar Islands including the expansion of the tri-services Andaman and Nicobar Command); port investment (Indian investment in Chabahar Port in Iran, providing India access to Afghanistan and Central Asia bypassing Pakistan; investment in Oman's Duqm port; engagement with Sri Lanka's Trincomalee port); and maritime domain awareness (the Information Fusion Centre for the Indian Ocean Region established in Gurugram in 2018, sharing ship tracking data with partner navies). India's Neighbourhood First policy and SAGAR (Security and Growth for All in the Region) doctrine articulate a vision of India as the leading provider of security and development in the Indian Ocean Region.

The Quadrilateral Security Dialogue (Quad), comprising India, the United States, Australia, and Japan, was originally constituted in 2007 following the cooperative response to the 2004 Indian Ocean tsunami (when the Core Group of naval responders - US, India, Japan, Australia - demonstrated effective maritime cooperation). The Quad was dormant from 2008 to 2017 following Australia's withdrawal under pressure from China, but was revived in 2017 and elevated to leader-level summits in 2021. The Quad focuses on free and open Indo-Pacific principles (freedom of navigation, rules-based order, counterbalancing Chinese coercion), maritime security and domain awareness, vaccine and health security, critical and emerging technologies, climate and clean energy, and supply chain resilience. India participates in the Quad as a co-equal partner while maintaining strategic autonomy, not treating it as a formal military alliance but as a framework for like-minded democracies to shape the regional order.

The Indo-Pacific concept, which India has adopted as a framing for its maritime strategy, understands the ocean space from the east coast of Africa through the Indian Ocean to the Pacific as a single strategic theatre rather than treating them as separate. India's Indo-Pacific Oceans Initiative (IPOI), announced by Prime Minister Modi in 2019, identified seven pillars: maritime security, maritime ecology, maritime resources, capacity building and resource sharing, disaster risk reduction and management, science technology and academic cooperation, and trade connectivity and maritime transport. France, Australia, Japan, the Maldives, Sri Lanka, Bangladesh, and Mauritius have associated themselves with different pillars of the IPOI, making it a framework for multilateral cooperation rather than a bilateral India-centric arrangement. India is also a founding member of the Indian Ocean Rim Association (IORA), which brings together 23 countries bordering the Indian Ocean to promote regional cooperation on trade, investment, maritime safety, fisheries management, disaster risk reduction, and tourism.

Relations with Neighbouring Countries

India's relations with its immediate neighbours in South Asia are shaped by the geographical reality of centrality: India shares borders with all SAARC countries (except Afghanistan, which shares a border with Pakistan), and its economic and demographic size (India's GDP is approximately 80 percent of total SAARC GDP) creates an asymmetry that smaller neighbours simultaneously benefit from and resent. The Neighbourhood First policy, articulated under the Modi government, prioritises India's relations with immediate neighbours and has involved enhanced connectivity projects, credit lines, development assistance, and high-level diplomatic engagement.

India-Pakistan relations are the most consequential bilateral relationship in South Asia and one of the most dangerous in the world, given that both states possess nuclear weapons and have fought four wars (1947, 1965, 1971, and the 1999 Kargil conflict) since independence. The core dispute is over Jammu and Kashmir, which both countries claim in full. The Line of Control (LoC) divides the territory into Indian-administered Jammu and Kashmir/Ladakh and Pakistani-administered Azad Kashmir and Gilgit-Baltistan. The Simla Agreement (1972) established the LoC and committed both countries to resolving disputes bilaterally. Pakistan's support for cross-border terrorism (the 2001 Parliament attack, the 2008 Mumbai attacks/26/11, the 2016 Pathankot and Uri attacks, the 2019 Pulwama attack) has kept bilateral relations in a deep freeze for most of the 2000s-2020s. The India-Pakistan composite dialogue process has been intermittently suspended following terrorist attacks. The Indus Waters Treaty (1960, brokered by the World Bank), which allocated the western rivers (Indus, Jhelum, Chenab) to Pakistan and the eastern rivers (Ravi, Beas, Sutlej) to India, has survived all four wars as an enduring framework of water-sharing - though India has served notice of intent to renegotiate in the context of escalating tensions. Trade between India and Pakistan was significantly curtailed after India revoked Pakistan's Most Favoured Nation (MFN) status following the 2019 Pulwama attack and Pakistan suspended bilateral trade. The SAARC framework has been effectively paralysed by India-Pakistan tensions.

India-China relations are shaped by the 3,488 km disputed boundary, the 1962 war (which established China's psychological advantage in the bilateral relationship and India's territorial loss of Aksai Chin in Ladakh), and the strategic competition for influence across Asia and the Indian Ocean. The boundary is disputed across three sectors: the Western Sector (Aksai Chin, controlled by China, claimed by India; the LAC in this sector has been relatively stable); the Middle Sector (Uttarakhand, Himachal Pradesh - relatively minor disputes); and the Eastern Sector (Arunachal Pradesh, which China claims as South Tibet/Zangnan, calling it a "disputed area" and periodically renaming places within it with Chinese names). India and China normalised relations after 1988 (Rajiv Gandhi's visit to Beijing) and developed a substantial trading relationship (China became India's largest import source) while managing the boundary through Confidence Building Measures (CBMs) including the 1993, 1996, 2005, and 2013 agreements. The June 2020 Galwan Valley clash in eastern Ladakh, in which 20 Indian soldiers and an undisclosed number of Chinese soldiers were killed (the first deaths on the India-China border since 1975), marked the most serious breakdown in bilateral relations in decades. India responded by banning hundreds of Chinese apps (TikTok, PUBG, etc.), restricting Chinese investment, and accelerating infrastructure development along the LAC (roads, forward airfields, border villages). The boundary standoff at several friction points in eastern Ladakh (Hot Springs, Gogra, Depsang, Demchok) has been partially resolved through disengagement at specific points since 2021, but the relationship remains fundamentally strained. India has progressively moved away from its earlier ambiguity toward aligning more closely with the United States and other democracies in balancing China.

India-Nepal relations are characterised by a unique open border (the 1950 Treaty of Peace and Friendship allows free movement of people and goods), deep cultural and religious connections (shared Hindu and Buddhist heritage, Pashupatinath in Kathmandu is the most sacred Shaivite site outside India), and significant economic interdependence (India accounts for approximately two-thirds of Nepal's trade and is the source of remittances from approximately 5-6 million Nepali workers in India). However, the relationship is periodically strained by: Nepal's border disputes with India (the Kalapani-Lipulek-Limpiyadhura trijunction area claimed by both countries, which flared into a public dispute in 2020 when India inaugurated a road to the Lipulek pass connecting Uttarakhand to the Kailash Mansarovar pilgrimage site, prompting Nepal to update its official map to include the disputed area); perceived Indian interference in Nepal's domestic politics; China's growing economic and infrastructure presence in Nepal (BRI projects, trans-Himalayan connectivity); and periodic water-sharing disputes over the Koshi, Gandak, and Mahakali rivers and shared hydropower projects.

India-Bangladesh relations are among the most transformed in South Asia over the past decade. Bangladesh (created in 1971 with Indian military intervention in the third India-Pakistan war, and thus having a foundational debt to India) has become India's largest trade partner in South Asia and a significant destination for Indian exports of cotton, machinery, and goods. The 2011 Land Boundary Agreement (ratified by India in 2015 after decades of delay due to domestic political opposition), which exchanged the Dahagram-Angarpota enclave and resolved the complex enclaves issue (163 Indian enclaves inside Bangladesh and 111 Bangladeshi enclaves inside India were exchanged), was a landmark resolution of a post-partition cartographic anomaly. The Teesta river water sharing agreement, signed by the central government in 2011 but blocked by West Bengal Chief Minister Mamata Banerjee on grounds of West Bengal's water needs, remains unresolved despite being the most significant outstanding bilateral issue. Transit and connectivity - the use of Bangladesh territory for Indian goods transit between West Bengal and the northeastern states (bypassing the Siliguri Corridor), and road-rail-waterway connectivity projects - have advanced significantly. The political situation in Bangladesh following the August 2024 ouster of Sheikh Hasina's government and the interim administration under Muhammad Yunus has introduced new uncertainty into the bilateral relationship.

India-Sri Lanka relations span centuries of cultural and religious connection (Ramayana traditions, Buddhism, Tamil cultural links) but have been complicated since independence by the question of Indian-origin Tamil plantation workers in Sri Lanka (statelessness issues resolved through the Sirima-Shastri Pact 1964 and Sirima-Gandhi Pact 1974), the Sri Lankan civil war (India's complicated role: training Tamil militant groups including the LTTE in the 1970s-80s, then intervening militarily through the Indian Peacekeeping Force 1987-90 following the Indo-Sri Lanka Accord brokered by Rajiv Gandhi, followed by the LTTE's assassination of Rajiv Gandhi in 1991 which permanently damaged Tamil sympathy in India), and the fishermen conflict in the Palk Strait (Indian fishermen from Tamil Nadu cross into Sri Lankan waters, leading to arrests, violence, and diplomatic protests). Post-civil war Sri Lanka has seen significant Chinese investment (Colombo Port City, Hambantota Port, infrastructure loans that created a debt crisis), to which India has responded with its own infrastructure and development assistance including the Trincomalee oil tank farm development and renewable energy projects. The 2022 Sri Lankan economic crisis (default on foreign debt, political turmoil, collapse of the Gotabaya Rajapaksa government) led India to provide approximately USD 4 billion in emergency credit lines, fuel, and food - substantially more than China's assistance - strengthening India's position as Sri Lanka's most important partner.

India-Myanmar relations are strategically important given the 1,643 km shared border and Myanmar's position as the gateway to Southeast Asia under India's Act East Policy. India has invested in the Kaladan Multimodal Transit Transport Project (linking Kolkata by sea to Sittwe port in Myanmar's Rakhine State, then by river to Paletwa, and then by road to Mizoram - providing India's northeast a connectivity alternative to the Siliguri Corridor) and the India-Myanmar-Thailand Trilateral Highway (connecting Moreh in Manipur to Mae Sot in Thailand via Myanmar, with an extension to Laos, Cambodia, and Vietnam under planning). The February 2021 military coup in Myanmar that overthrew the democratically elected government of Aung San Suu Kyi has created a complex situation: India has not formally condemned the coup (unlike Western governments) to preserve its engagement with the military junta and avoid pushing Myanmar further toward China, but has faced the consequences of the resulting civil war and insurgency in Myanmar in the form of refugees crossing into Mizoram and Manipur and the disruption of connectivity projects.

India-Bhutan relations are unique: Bhutan is India's most trusted neighbour, with India providing security guarantees (no Indian troops are stationed in Bhutan, but India has trained the Royal Bhutan Army and provides defence assistance), hydro-power as the centrepiece of economic relations (Bhutan exports hydropower to India from its rivers - the Chukha, Tala, Mangdechhu hydroelectric projects - making hydropower the largest export earning for Bhutan and providing cheap electricity to eastern India), and development assistance under which India is Bhutan's largest bilateral aid donor. The India-Bhutan Treaty of Peace and Friendship (1949, revised 2007) provides for free movement of people and goods and historically coordinated foreign policies, though Bhutan now conducts its own foreign relations. The most significant recent development is the China-Bhutan boundary dispute: China and Bhutan share an unsettled boundary, and China's claim to the Doklam plateau (which India claims is within the Indian sphere of interest as it directly overlooks the Siliguri Corridor) led to the 73-day Doklam standoff in 2017 between Indian and Chinese forces. China and Bhutan have been holding boundary talks independently of India, creating some anxiety in New Delhi about a potential China-Bhutan settlement that might disadvantage India's strategic interests.

Nuclear Geography

India's nuclear weapons programme emerged from the intersection of the security threats from China (which tested its first nuclear device in 1964, one year after the 1962 war) and Pakistan, and from India's aspirations to great power status. India's first nuclear test, code-named Smiling Buddha (officially Pokhran-I), was conducted on 18 May 1974 at Pokhran in Rajasthan's Thar Desert under Prime Minister Indira Gandhi - described officially as a "peaceful nuclear explosion" to avoid triggering sanctions. The test shocked the world and led to the formation of the Nuclear Suppliers Group (NSG), which restricted technology transfers to countries outside the NPT framework. India's second series of nuclear tests, Operation Shakti (Pokhran-II), was conducted on 11-13 May 1998 at Pokhran under Prime Minister Atal Bihari Vajpayee, consisting of five tests including thermonuclear and fission devices. Pakistan responded with its own tests (Chagai-I and Chagai-II) in May 1998, making both South Asian countries overt nuclear weapons states and transforming the subcontinent's strategic geography into a zone of nuclear deterrence. Both countries are not signatories to the Nuclear Non-Proliferation Treaty (NPT), having never joined the NPT framework from the outset (unlike North Korea which withdrew).

India's nuclear doctrine, articulated in 2003, rests on three foundational principles: No First Use (NFU) - India will not be the first to use nuclear weapons against any state (though India reserves the right to use nuclear weapons in response to a biological or chemical weapons attack, and there is ongoing debate about whether India's NFU commitment remains absolute); Credible Minimum Deterrence - India maintains the minimum nuclear forces sufficient to deter nuclear attack, without seeking parity with larger nuclear powers; and Massive Retaliation - any nuclear attack on India or Indian forces anywhere will be met with a nuclear retaliation designed to inflict unacceptable punishment. India's nuclear command is exercised through the Nuclear Command Authority (NCA), chaired by the Prime Minister with the Strategic Forces Command (SFC) as the operational arm. India's no-first-use doctrine and declared focus on deterrence rather than warfighting distinguishes its doctrine from Pakistan's, which has not adopted NFU and threatens first use of tactical nuclear weapons against conventional Indian military advances (a doctrine driven by Pakistan's conventional military inferiority to India).

India's nuclear triad - the capability to deliver nuclear weapons from land, air, and sea - is progressively being completed. Land-based delivery is provided by the Agni ballistic missile series: Agni-I (700-900 km range), Agni-II (2,000 km range), Agni-III (3,000-5,000 km range), Agni-IV (4,000 km range), and Agni-V (intercontinental range, approximately 5,000-8,000 km, capable of reaching all of China including Beijing and Shanghai from Indian territory, tested multiple times and nearing induction). The Prithvi short-range ballistic missiles provide battlefield nuclear delivery capability. Air delivery is provided by the Mirage 2000 and Jaguar aircraft, to be supplemented by the Rafale which has been delivered to the Indian Air Force. Sea-based delivery is provided by the nuclear-powered ballistic missile submarine INS Arihant, which completed India's nuclear triad when it conducted its first deterrence patrol in 2018, with the Sagarika (K-15) submarine-launched ballistic missile (SLBM) with a range of 700 km and the K-4 SLBM (3,500 km range) under development. The second SSBN INS Arighaat was commissioned in 2024. A longer-range K-5 SLBM (6,000+ km range) is reportedly under development.

The geography of nuclear deterrence in South Asia creates a complex strategic environment. India's nuclear forces are oriented primarily toward China (the Agni-V is specifically designed to address the China deterrence gap, as earlier Agni variants could not reach all Chinese cities from Indian territory) and secondarily toward Pakistan. Pakistan's nuclear forces are oriented entirely toward India and are structured around a full-spectrum deterrence posture using tactical nuclear weapons (the Nasr short-range missile) to offset India's conventional military superiority. The India-Pakistan nuclear relationship involves minimum distances (proximity of forces, short warning times), political volatility (the nuclear button is held by the Pakistani Army, not the civilian government, creating command and control uncertainties), and the risk of miscalculation during crises. The 2019 Balakot air strikes (the first time Indian military aircraft struck a target inside Pakistan since 1971) and Pakistan's retaliatory cross-border air action demonstrated that military escalation can occur even under conditions of mutual nuclear deterrence.

The India-US Civil Nuclear Agreement (123 Agreement, 2008) was a landmark that ended India's nuclear isolation. The agreement, negotiated during the George W. Bush and Manmohan Singh governments, allowed civilian nuclear cooperation between India and the United States despite India not being an NPT signatory, on the basis of India's voluntary separation of civilian and military nuclear facilities, India's commitment to IAEA safeguards on civilian facilities, and India's strong non-proliferation record. The agreement was a political achievement for both sides: for India, it ended 34 years of nuclear isolation and opened access to nuclear fuel, technology, and international nuclear commerce; for the US, it recognised India as a de facto nuclear weapons state and deepened strategic partnership. The NSG waiver in 2008 (enabling all NSG members to engage in civilian nuclear commerce with India) was essential to operationalising the agreement. Subsequently, India has concluded civilian nuclear agreements with Russia, France, the UK, Canada, Australia, Japan, and South Korea. India seeks full NSG membership, which is blocked by China on the grounds that Pakistan should simultaneously receive NSG membership or that non-NPT states cannot be admitted.

India's nuclear geography also encompasses its thorium reserves, which are among the world's largest (approximately 846,000 tonnes in beach sands primarily in Kerala, Tamil Nadu, and Andhra Pradesh). India's three-stage nuclear power programme, conceived by Dr. Homi Bhabha, is designed to eventually use thorium as fuel: Stage 1 uses natural uranium in Pressurised Heavy Water Reactors (PHWRs) to generate electricity and plutonium; Stage 2 uses the plutonium in Fast Breeder Reactors (FBRs) to breed more plutonium and uranium-233 from thorium; Stage 3 uses the uranium-233 from Stage 2 to fuel Advanced Heavy Water Reactors (AHWRs) running primarily on thorium. The Prototype Fast Breeder Reactor (PFBR) at Kalpakkam (Tamil Nadu) under the Department of Atomic Energy is the critical Stage 2 facility whose completion (long-delayed, now expected imminently) will enable transition to the thorium cycle. India's nuclear power capacity stands at approximately 7,480 MW (23 operating reactors) with ambitious plans for expansion.

South-South Cooperation

South-South Cooperation (SSC) refers to the exchange of resources, technology, knowledge, and expertise among developing countries of the Global South (Latin America, Africa, Asia, and the Pacific) in contrast to the traditional North-South development assistance model in which wealthy developed countries provide aid to poor developing countries. India is one of the largest and most active proponents of South-South Cooperation, grounded in the principles of solidarity, non-interference, mutual benefit, and respect for national sovereignty that distinguish SSC from traditional donor-recipient aid relationships.

India's development cooperation is coordinated through the Development Partnership Administration (DPA) in the Ministry of External Affairs, established in 2012 to consolidate India's scattered development assistance activities. India's development partnership portfolio includes: Lines of Credit (concessional loans) extended through the Export-Import Bank of India to developing countries for infrastructure, energy, and connectivity projects, totalling over USD 30 billion committed to approximately 64 countries (as of 2023), with Africa being the largest regional recipient; grant assistance for capacity building, humanitarian relief, and project development; technical assistance through the Indian Technical and Economic Cooperation (ITEC) programme, which since 1964 has provided training to over 200,000 officials, professionals, and technicians from developing countries (approximately 10,000 annually in peacetime) in Indian institutions; and cooperation in the form of sharing India's development experience in agriculture, health, education, space, and digital technology.

The India-Africa relationship has grown significantly through three India-Africa Forum Summits (2008, 2011, 2015), with the 2015 Delhi Summit committing USD 600 million in grant assistance and USD 10 billion in lines of credit to Africa over five years. India has provided development assistance for infrastructure (roads, railways, electricity, rural connectivity), health (pharmaceutical supplies, health worker training, hospitals), agriculture (soil health, crop varieties, irrigation), and capacity building (ITEC training, ICCR scholarships). India's approach to Africa emphasises complementarity rather than competition with Chinese engagement, though India and China do compete for influence across African capitals and resource contracts.

The Indian Technical and Economic Cooperation (ITEC) programme is the flagship of India's South-South technical cooperation. Established in 1964 during Prime Minister Lal Bahadur Shastri's tenure, ITEC provides civilian (and separately the Special Commonwealth Assistance for Africa Programme, SCAAP, for Commonwealth countries) and military training to officials and professionals from developing countries, primarily in Africa, Southeast Asia, Central Asia, and the Pacific. ITEC civilian training covers a wide range of subjects including IT and software, public administration, banking, rural development, parliamentary practices, yoga, and English language. The Indian Council for Cultural Relations (ICCR) also provides scholarships to students from developing countries to study in Indian universities, with a particular focus on Africa and the neighboring countries.

India's development of digital public infrastructure - particularly the India Stack (Aadhaar biometric identity, UPI digital payments, DigiLocker document storage, and the open-source Beckn protocol for digital commerce) - has been offered to developing countries as a template for inclusive digital development. India has supported the adoption of UPI in Singapore, UAE, France, Sri Lanka, Mauritius, Nepal, and other countries. The Unified Health Interface and Co-WIN vaccination platform have been offered as digital health tools to developing countries through the Coalition for Epidemic Preparedness Innovations (CEPI) and bilateral arrangements. India's experience of using technology for direct benefit transfers, financial inclusion, and transparent governance is being actively promoted as a development model.

The International Solar Alliance (ISA), co-founded by India and France at COP21 in Paris in December 2015 and headquartered in Gurugram with a treaty framework opened to 121 sunshine countries between the Tropics of Cancer and Capricorn (later expanded to all UN members), represents India's most significant multilateral initiative in South-South cooperation on clean energy. ISA aims to mobilise over USD 1 trillion in solar investment by 2030, promote solar technology deployment, facilitate affordable finance for solar projects, and build solar energy capacity in developing countries. ISA has over 90 member and signatory countries and has launched programmes for solar applications in agriculture (solar pumps), health (solar for health facilities), transport, and energy access in least developed countries and small island states.

The Coalition for Disaster Resilient Infrastructure (CDRI), launched by India at the UN Climate Action Summit in September 2019 and headquartered in New Delhi, is a multilateral initiative to promote infrastructure systems that are resilient to climate and disaster risks. CDRI addresses the massive costs (estimated at USD 18 trillion globally by 2040) of damage to infrastructure from climate-related disasters and builds developing country capacity to design, build, and maintain climate-resilient infrastructure. It has over 30 member countries and several multilateral organisations including the EU, World Bank, and UN agencies.

India's role in South-South Cooperation is also expressed through its active participation in multilateral forums that represent the Global South: the Group of 77 (G77, a coalition of 134 developing countries at the UN); the Non-Aligned Movement (NAM, founded by India's Nehru, Egypt's Nasser, Yugoslavia's Tito, Indonesia's Sukarno, and Ghana's Nkrumah at the Bandung Conference 1955, formalised at Belgrade 1961, now with 120 member states); BRICS (Brazil, Russia, India, China, South Africa, expanded at the 2023 Johannesburg Summit to include Iran, Egypt, Ethiopia, UAE, Saudi Arabia, and Argentina - though Argentina later withdrew); the Shanghai Cooperation Organisation (SCO, to which India was admitted as a full member in 2017 alongside Pakistan, and which now also includes Iran); and IBSA (India, Brazil, South Africa, a triangular South-South forum among the largest democracies of the Global South).

India's G20 Presidency in 2023 (the summit was held in New Delhi in September 2023) was a significant platform for advancing India's vision of reformed multilateralism, Global South interests, and South-South cooperation. India secured the inclusion of the African Union as a permanent G20 member (the first time the AU was admitted as a full member), gave voice to the concerns of the Global South (through the Voice of the Global South Summit hosted by India in January 2023 with over 125 countries participating), and championed priorities including debt restructuring for developing countries, digital public infrastructure as a global good, climate finance and just energy transition, and food and fertiliser security. The New Delhi G20 Leaders' Declaration was adopted by consensus (a diplomatic achievement given the Russia-Ukraine divide), and India used its presidency to position itself as the indispensable voice of the developing world in global governance.
