India’s Border Disputes with Neighbors: A Detailed Analysis
This topic is highly important for UPSC Prelims GS Paper 1 (Geography & Current Affairs) and Mains GS Paper 2 (International Relations) as questions are often asked on India’s border issues, strategic geography, and foreign policy.
India’s international boundaries are crucial for its national security, development, and regional stability. As the seventh-largest country in the world, India shares over 15,106.7 km of land borders and has a coastline stretching 7,516.6 km. With seven land neighbors—China, Pakistan, Nepal, Bhutan, Bangladesh, Myanmar, and Afghanistan—its borders are both a source of cooperation and frequent disputes, impacting domestic and foreign policy profoundly.
Overview of India’s Borders
- Total land borders: 15,106.7 km
- Coastline: 7,516.6 km
- Land neighbors (clockwise from northwest): Afghanistan (106 km), Pakistan (3,323 km), China (3,488 km), Nepal (1,751 km), Bhutan (699 km), Bangladesh (4,096.7 km), Myanmar (1,643 km).
- Maritime neighbors: Sri Lanka (via Palk Strait) and Maldives (south-west Indian Ocean).

Major Border Disputes
India-China
- Aksai Chin: Occupied by China but claimed by India (Ladakh); strategic for both nations.
- Arunachal Pradesh: Entire state claimed as “South Tibet” by China.
- LAC (Line of Actual Control): Undemarcated, leading to frequent stand-offs (notably the Galwan clash of 2020).
- Historical background: 1962 India-China war over disputed borders; subsequent skirmishes and failed rounds of talks.
India-Pakistan
- Kashmir Issue: Disputed region split by the Line of Control (LoC); root of three wars (1947, 1965, 1999) and ongoing tensions.
- Sir Creek: A 96-km estuary in the Rann of Kutch, claimed by both for maritime boundary extension.
- Siachen Glacier: The world’s highest battlefield, held by India but claimed by Pakistan.
India-Nepal
- Kalapani, Lipulekh, Limpiyadhura: Territories at the tri-junction of India, Nepal, and China; dispute intensified after Nepal released a new map claiming these regions in 2020.
- Basis: Differing interpretations of the source of river Kali as per the 1816 Sugauli Treaty.
India-Bangladesh
- Enclaves/Chhitmahals: More than 160 enclaves on both sides resolved by the Land Boundary Agreement (LBA), 2015.
- Teesta River Water Dispute: Sharing of river waters remains unresolved; crucial for livelihoods in West Bengal and Bangladesh.
India-Myanmar & Bhutan
- Myanmar: Minor, localized border disputes; issues focus more on cross-border insurgency and security (e.g., Naga and Manipuri insurgent camps in Myanmar territory).
- Bhutan: No significant territorial disputes, but India helps secure Bhutan’s border with China, which remains undemarcated in North Bhutan.
Geopolitical & Security Implications
- Defense: The security of borders is paramount—India invests heavily in fencing, roads, checkposts, and deploying forces (e.g., ITBP, BSF, Assam Rifles).
- Cross-border Terrorism: Pakistan-based groups’ infiltration across Kashmir LoC, and insurgent movements across Myanmar, challenge India’s internal security.
- Trade: Boundary uncertainty limits trade corridors, though Bangladesh-India and Myanmar-India trade are growing.
- China’s Role: Asserting claims in South Asia (CPEC, infrastructure in disputed zones), China influences border complexity, especially on the India-Pakistan front.
Efforts for Resolution
- Treaties & Agreements:
- Simla Agreement (1972): Established the current LoC with Pakistan.
- Land Boundary Agreement (2015): Settled enclave disputes with Bangladesh.
- Special Representatives Talks: Framework for India-China border dialogue (since 2003; ongoing).
- Bilateral Talks: India and Nepal have established several joint technical-level discussions. India-Myanmar meets regularly for border management and counter-insurgency operations.
- Infrastructure: The Indian government is constructing all-weather roads, bridges, and advanced monitoring systems along northern and northeastern borders.
Current Developments (as of October 2025)
- India-China: Multiple rounds of diplomatic and military talks post-Galwan (2020), but the LAC remains volatile in eastern Ladakh and Arunachal Pradesh.
- India-Nepal: Both countries maintain dialogue over the Kalapani-Lipulekh issue, despite occasional tensions over new map assertions.
- India-Pakistan: 2021 saw the reiteration of a ceasefire along the LoC, but sporadic ceasefire violations and terror infiltrations occur.
- India-Bangladesh: Teesta water sharing remains pending; cooperation is otherwise strong since the LBA.
Way Forward
- Robust Diplomacy: Sustain regular dialogue and confidence-building measures (CBMs) with neighbors.
- Border Infrastructure: Enhance roads, surveillance, and fencing for quick defense response and local development.
- People-to-People Connect: Deepen cultural, economic, and cross-border people linkages to lower tensions.
- Multilateral Forums: Leverage groupings like BIMSTEC, SAARC, SCO for dialogue and regional confidence.
- Balanced Security: Modernize border forces and adopt tech-driven border management (satellite monitoring, UAVs).
Conclusion
India’s geography is both an advantage and a challenge. Managing borders with seven neighbors in complex terrains, amidst historical disputes and contemporary threats, is central to India’s national security and regional stability. While historical legacies and changing geopolitics complicate the landscape, continued dialogue, modernization, and smart diplomacy remain the key to progress. For aspirants, understanding these borders is essential to analyze India’s foreign policy, internal security, and its aspirations as a regional leader.
