India–Nepal Relations

Recent remarks by the Prime Minister of Nepal on the Kalapani–Lipulekh–Limpiyadhura boundary dispute, emphasizing an objective examination of facts and an amicable resolution through dialogue, along with renewed high-level diplomatic engagements, indicate a potentially more pragmatic phase in India–Nepal relations.

Nepal's emerging leadership is increasingly prioritizing economic development, sovereign equality, and constructive diplomacy, creating opportunities for a more balanced and forward-looking bilateral partnership. However, challenges relating to border disputes, Chinese influence, open-border security, and water-sharing continue to shape the relationship.

India–Nepal Boundary Dispute

Treaty of Sugauli (1816)

The roots of the dispute lie in the Treaty of Sugauli (1816), signed between the Kingdom of Nepal and the British East India Company after the Anglo-Nepalese War. The treaty designated the Kali (Mahakali) River as Nepal's western boundary but did not clearly identify its source, giving rise to competing territorial claims.

Nepal's Position

Nepal maintains that the Kali River originates from Limpiyadhura, the westernmost stream in the region. Based on this interpretation, Kalapani, Lipulekh, and Limpiyadhura fall within Nepalese territory.

To formalize its claim, Nepal amended its Constitution in 2020 to incorporate a revised political map including these territories. The government subsequently reinforced its position by issuing a new NPR 100 banknote carrying the updated map.

India's Position

India argues that the river originates near Kalapani, east of Limpiyadhura, and therefore regards the disputed territory as part of Pithoragarh district of Uttarakhand. India exercises both administrative and military control over the region.

Strategic Importance

The disputed area holds significant strategic value because of its proximity to China. The Lipulekh Pass serves as an important trade route and constitutes one of the principal gateways for the Kailash Mansarovar Yatra, enhancing its geopolitical and economic significance.

Changing Nature of Nepal's Approach Towards India

From Ideology to Pragmatism

Nepal is increasingly emphasizing economic cooperation over political rhetoric. This shift is evident in the agreement to export 10,000 MW of hydropower to India over the next decade, reflecting a stronger focus on mutual economic gains.

From Special Relationship to Sovereign Equality

Kathmandu seeks a relationship based on sovereign equality and mutual respect, moving beyond the traditional narrative of a special relationship. Nepal increasingly emphasizes diplomatic parity and independent decision-making in its interactions with India.

A More Rational Approach to Border Issues

Boundary disputes are gradually being treated as technical and diplomatic matters rather than instruments of nationalist mobilization. The preference for dialogue and evidence-based solutions indicates a more pragmatic approach to bilateral differences.

Greater Strategic Autonomy

Nepal seeks to pursue an independent foreign policy that balances its relations with both India and China while relying on diplomacy, historical evidence, and national interests rather than external alignments.

Key Outcomes of Nepal's Foreign Minister's Visit to India

Cross-Border Digital Payments

India and Nepal launched a Peer-to-Peer (P2P) linkage connecting India's Unified Payments Interface (UPI) with Nepal's National Payments Interface (NPI). The initiative enables real-time and low-cost cross-border remittances, deepening financial integration and promoting financial inclusion.

Language Technology Cooperation

An MoU between Digital India Bhashini and Kathmandu University aims to develop a voice-first digital language translation platform in Nepal, strengthening technological collaboration and digital accessibility.

Challenges in India–Nepal Relations

Boundary Disputes

The unresolved Kalapani–Lipulekh–Limpiyadhura issue continues to influence bilateral relations and requires sustained diplomatic engagement and confidence-building measures.

China's Growing Influence

China's expanding economic and strategic presence in Nepal through the Belt and Road Initiative (BRI) presents new geopolitical challenges for India in the Himalayan region.

Open Border Security

The India–Nepal open border, while facilitating people-to-people ties, also poses challenges relating to illegal migration, smuggling, trafficking, and cross-border criminal activities.

Water-Sharing and River Management

Differences over water resources, flood management, and hydropower projects remain important issues requiring institutional cooperation and mutual trust.

Overview

The India–Nepal relationship is a cornerstone of India's Neighbourhood First Policy and is characterized by deep historical, cultural, economic, and strategic linkages. The two countries share an open border, close people-to-people ties, strong defence cooperation, and growing economic integration, making the partnership one of the most unique in South Asia.

Trade and Economic Relations

India is Nepal's largest trading partner and biggest export destination. At the same time, Nepal has emerged as India's 14th largest export destination in 2024–25, improving significantly from the 28th position in 2014.

Nepal primarily exports edible oils, tea, coffee, jute, and agricultural products to India, while it depends heavily on India for imports of petroleum products, iron and steel, cereals, vehicles, machinery, and manufactured goods. The extensive economic interdependence reflects the close integration of the two economies.

Defence and Security Cooperation

The defence relationship between the two countries is built upon deep institutional trust and shared military traditions. The Gorkha Regiment of the Indian Army includes nearly 32,000 Gorkha soldiers from Nepal, symbolizing a unique military partnership.

Military cooperation is further strengthened through the annual 'Surya Kiran' joint military exercise, which enhances interoperability, combat readiness, counter-terrorism capabilities, and disaster-response coordination between the armed forces of both nations.

The two countries also cooperate extensively in border management, intelligence sharing, and efforts to combat transnational crimes and terrorism.

Cross-Border Connectivity Infrastructure

Physical connectivity between India and Nepal has expanded considerably in recent years. Important cross-border railway projects include the Jayanagar–Bijalpura–Bardibas railway line, which represents Nepal's first broad-gauge railway connection, along with the Jogbani–Biratnagar rail link and the proposed Raxaul–Kathmandu railway project.

The Mechi Bridge, spanning the Mechi River, serves as an important international border crossing connecting Panitanki in West Bengal with eastern Nepal, facilitating trade and movement of people.

Energy connectivity has also improved through the Motihari–Amlekhgunj petroleum pipeline, commissioned in 2019 as South Asia's first cross-border petroleum pipeline, ensuring reliable and cost-effective fuel supplies to Nepal.

Energy and Digital Integration

Energy cooperation has emerged as a major pillar of bilateral relations. Under the Power Trade Agreement of 2024, Nepal is committed to exporting 10,000 MW of hydropower to India over the next decade, strengthening regional energy security and supporting India's clean energy transition.

Digital integration has witnessed significant progress through the operationalization of cross-border QR-based payments enabled by interoperability between India's Unified Payments Interface (UPI) and Nepal's FonePay system. This initiative facilitates seamless financial transactions and enhances economic connectivity.

River Basin Management and Water Cooperation

The two countries share several major transboundary rivers, making water cooperation an important aspect of bilateral relations. Long-standing agreements such as the Kosi Agreement (1954), Gandak Agreement (1959), and the Mahakali Treaty (1996) provide frameworks for cooperation in irrigation, flood control, hydropower development, and water resource management.

Cooperation also extends to the Karnali River basin, reflecting the strategic importance of water resources for both countries.

Disaster Management and Soft Power

India has consistently acted as the first responder during humanitarian crises in Nepal. Indian assistance during the 2015 Nepal earthquake and the Covid-19 pandemic demonstrated the strength of bilateral cooperation in Humanitarian Assistance and Disaster Relief (HADR) operations.

Cultural diplomacy remains another important dimension of the relationship. The Buddhist Circuit and Ramayana Circuit under India's Swadesh Darshan Scheme connect important religious and cultural centres such as Lumbini, the birthplace of Lord Buddha, and Janakpur, associated with Goddess Sita, thereby strengthening civilizational ties.

Strategic Importance of India–Nepal Relations

Nepal as a Geographic Buffer

Nepal occupies a critical position between India and China, functioning as an important buffer state in the Himalayan region. Stability in Nepal contributes significantly to India's northern security environment and helps safeguard the Indo-Gangetic plains from potential strategic threats.

Security of the Siliguri Corridor

A stable and friendly Nepal is crucial for the security of India's Siliguri Corridor, commonly known as the Chicken's Neck, which connects mainland India with the northeastern states. Any external influence or instability in Nepal could have significant implications for this strategically sensitive region.

Open Border Security

The 1,751-kilometre open border facilitates extensive people-to-people interactions, trade, employment, and cultural exchanges. However, it also necessitates close cooperation to address challenges such as smuggling, illegal migration, human trafficking, and cross-border criminal activities.

Countering China's Growing Influence

China has significantly expanded its presence in Nepal through the Belt and Road Initiative (BRI) and various infrastructure projects. For India, strengthening economic integration, connectivity projects, and development partnerships remains essential to maintaining its strategic influence and preserving Nepal's close engagement with South Asia.

Water and Energy Security

Nepal's river systems play a vital role in flood management and irrigation in northern India, while its immense hydropower potential contributes to India's renewable energy ambitions. Enhanced cooperation in water and energy therefore serves mutual strategic interests.

Challenges in India–Nepal Relations

The China Factor

Nepal's increasing engagement with China through BRI projects, the proposed Trans-Himalayan Railway, and Chinese-funded infrastructure such as Pokhara International Airport has raised strategic concerns in India regarding regional influence and security dynamics.

Legacy of the 2015–16 Blockade Controversy

The Madhesi protests of 2015–16 and Nepal's allegations of an unofficial Indian blockade generated anti-India sentiments within Nepal. Although India denied these accusations, the episode encouraged Nepal to diversify its external partnerships and strengthen relations with China.

Changing Diplomatic Dynamics

Nepal's contemporary leadership increasingly emphasizes sovereign equality, diplomatic protocol, and non-interference, moving away from the traditional notion of a special relationship with India. This requires a recalibration of bilateral engagement based on mutual respect and parity.

Open Border Challenges

The porous border facilitates transnational crimes, including smuggling, illegal migration, trafficking, and the circulation of Fake Indian Currency Notes (FICN). India's Sashastra Seema Bal (SSB) regularly intercepts illegal cross-border movements, highlighting the security challenges associated with an open border system.

Water-Sharing and Flood Management Issues

Despite extensive cooperation, disagreements continue regarding water-sharing arrangements and project implementation on the Kosi, Gandak, and Mahakali rivers. Delays in projects such as the 5,040 MW Pancheshwar Multipurpose Project and disputes relating to embankment maintenance and waterlogging in Nepal's Terai region remain important irritants.

Media-Driven Nationalism

Nationalistic narratives and media controversies often intensify bilateral disputes. Issues such as Nepal's issuance of NPR 100 banknotes featuring disputed territories demonstrate how domestic political considerations can influence public perceptions and diplomatic relations.

Measures to Strengthen India–Nepal Relations

Modernizing Bilateral Frameworks

Both countries should review the Eminent Persons Group (EPG) Report and consider updating aspects of the 1950 Treaty of Peace and Friendship to address Nepal's concerns regarding sovereign equality and contemporary geopolitical realities.

Improving Infrastructure Delivery

Timely completion of major projects such as the Arun-III Hydropower Project, cross-border railway links, and the expansion of the Motihari–Amlekhgunj pipeline will strengthen India's developmental credibility and deepen economic integration.

Depoliticizing Boundary Disputes

The Boundary Working Group (BWG) and Foreign Secretary-level mechanisms should be empowered to address the Kalapani–Lipulekh–Limpiyadhura dispute through technical and diplomatic dialogue rather than political confrontation.

Transforming Water Cooperation

Accelerating the Pancheshwar Multipurpose Project, improving flood-management coordination on the Kosi and Gandak rivers, and developing transparent benefit-sharing mechanisms can convert water resources into engines of shared prosperity.

Expanding Energy Partnership

The successful implementation of the agreement to export 10,000 MW of hydropower from Nepal to India requires stronger cross-border transmission infrastructure and greater investment in renewable energy cooperation.

Strengthening People-to-People Ties

Educational exchanges, cultural connections, the open-border system, and the unique military relationship between the two countries should continue to serve as foundations for long-term trust and cooperation.

Respecting Nepal's Sovereign Sensitivities

India's engagement with Nepal must increasingly emphasize mutual respect, non-interference, and sovereign parity, reflecting Nepal's aspirations for an equal partnership rather than a traditional special relationship.

Countering External Influence Through Connectivity

Instead of geopolitical competition, India can strengthen its position by deepening economic integration through railways, integrated check posts (ICPs), energy grids, digital connectivity, and trade facilitation, thereby remaining Nepal's most reliable development partner.

Conclusion

The emergence of a more pragmatic and economically oriented leadership in Nepal presents an opportunity to redefine bilateral relations on the basis of sovereign equality, economic integration, and mutual strategic interests. By addressing longstanding concerns, accelerating connectivity projects, and strengthening people-to-people linkages, India and Nepal can build a modern, resilient, and mutually beneficial partnership that contributes to stability and prosperity across the Himalayan region
