India Pakistan Relations

1. Introduction

India and Pakistan share one of the most complex and sensitive bilateral relationships in South Asia, shaped by the Partition of 1947, historical conflicts, territorial disputes, cross-border terrorism and nuclear rivalry. As immediate neighbours sharing a 3,323 km international border and the Line of Control (LoC) in Jammu & Kashmir, developments in bilateral relations have a direct impact on regional security, economic cooperation and peace in South Asia. Despite periodic confidence-building measures and diplomatic initiatives, India Pakistan Relations have remained largely adversarial due to unresolved issues such as Jammu & Kashmir, cross-border terrorism, the Indus Waters Treaty and border disputes.

India’s policy towards Pakistan is guided by the principles of zero tolerance towards terrorism, peaceful resolution of bilateral issues through bilateral mechanisms and respect for sovereignty and territorial integrity. While cooperation has existed in areas such as the Indus Waters Treaty, the Kartarpur Corridor, humanitarian exchanges and ceasefire mechanisms, repeated terrorist attacks and border tensions have prevented the normalisation of relations. As nuclear-armed neighbours, both countries also play a crucial role in maintaining strategic stability in South Asia. These aspects are important for India Pakistan Relation BPSC Notes pdf and BPSC Mains preparation.

India–Pakistan relations have remained highly strained following the Pahalgam terrorist attack (April 2025) and Operation Sindoor, under which India carried out precision strikes against terrorist infrastructure in Pakistan and Pakistan-occupied Kashmir. In response, India placed the Indus Waters Treaty (1960) in abeyance, suspended most bilateral engagements and reiterated that terrorism and dialogue cannot go together. The Indus Waters Treaty continues to remain in abeyance, while disputes over water sharing and cross-border terrorism dominate bilateral relations. India Pakistan Relations therefore remain a critical topic for understanding South Asian security and India’s foreign policy.

2. Evolution of India–Pakistan Relations

• 1947–1948: Following the Partition of British India, the first Indo-Pak war broke out over Jammu & Kashmir, leading to a UN-mediated ceasefire and the establishment of the Ceasefire Line (later the Line of Control (LoC)). India Pakistan Relations began with this conflict and the Kashmir dispute.
• 1965–1972: The two countries fought the 1965 War and the 1971 War, which resulted in the creation of Bangladesh. The Simla Agreement (1972) established the LoC and committed both countries to resolve disputes bilaterally.
• 1998–1999: Both countries declared themselves nuclear weapon states after conducting nuclear tests in 1998. Despite the Lahore Declaration (1999) aimed at improving relations, the Kargil War (1999) severely damaged bilateral trust.
• 2001–2019: Relations remained strained due to major terrorist attacks, including the 2001 Parliament attack, 2008 Mumbai attacks, 2016 Uri attack and 2019 Pulwama attack, leading to military responses, suspension of dialogue and deterioration of bilateral relations.
• 2025–2026: India Pakistan Relations reached a new low after the Pahalgam terrorist attack and Operation Sindoor, with India placing the Indus Waters Treaty in abeyance, suspending most bilateral engagements and maintaining that terrorism and dialogue cannot go together.

3. Pillars of India–Pakistan Relations

Political, Diplomatic & Economic Relations

• Limited Political Engagement: India’s policy is that terrorism and dialogue cannot go together. Bilateral political engagement remains limited, with contacts taking place mainly through diplomatic channels and multilateral forums. This remains a key feature of India Pakistan Relations.
• Diplomatic Relations: Following the Pahalgam terrorist attack (2025) and Operation Sindoor, both countries downgraded diplomatic engagement, reduced the strength of diplomatic missions and suspended most bilateral exchanges.
• Economic Relations: Bilateral trade has declined sharply since 2019, when Pakistan suspended most trade relations after India’s constitutional changes in Jammu & Kashmir. At present, formal bilateral trade is minimal, with only limited essential items moving through permitted channels, while some trade occurs indirectly via third countries. This has significantly affected India Pakistan Relations.
• Humanitarian Cooperation: Despite strained relations, limited cooperation continues on religious pilgrimages (Kartarpur Corridor), exchange of fishermen and civilian prisoners, humanitarian issues and consular access.
• Strategic Significance for India: Stable diplomatic relations are essential for reducing tensions, preventing military escalation, ensuring regional stability and creating conditions for any future dialogue, provided Pakistan takes credible and irreversible action against cross-border terrorism. These factors remain important for understanding India Pakistan Relation BPSC Notes pdf.

Security, Defence & Nuclear Dimension

• Nuclear-Armed Neighbours: India and Pakistan are both declared nuclear weapon states since 1998, making South Asia one of the world’s most sensitive nuclear flashpoints. The presence of nuclear weapons increases the importance of crisis management and strategic restraint in India Pakistan Relations.
• Line of Control (LoC): The Line of Control (LoC) in Jammu & Kashmir remains the principal military flashpoint. Issues such as ceasefire violations, infiltration attempts, cross-border firing and terrorist infiltration periodically heighten tensions.
• Ceasefire Understanding (2021): In February 2021, the Directors General of Military Operations (DGMOs) of both countries reaffirmed the ceasefire along the LoC and all other sectors. Although the understanding has largely reduced ceasefire violations, infiltration and terrorist incidents continue to pose security challenges.
• Counter-Terrorism & Military Response: India follows a policy of zero tolerance towards terrorism and has demonstrated its willingness to respond through operations such as the 2016 Surgical Strikes, 2019 Balakot Air Strike and Operation Sindoor (2025) against terrorist infrastructure. These developments have had a major impact on India Pakistan Relations.
• Siachen Glacier: The Siachen Glacier, the world’s highest battlefield, remains an unresolved military dispute. Both countries maintain heavy troop deployments despite harsh climatic conditions, resulting in significant financial and logistical costs.
• Sir Creek Dispute: The Sir Creek dispute involves the delimitation of a 96-km estuary in the Rann of Kutch, affecting the maritime boundary, fishing rights and Exclusive Economic Zone (EEZ) claims in the Arabian Sea.
• Confidence Building Measures (CBMs): Both countries have adopted several CBMs, including the DGMO hotline, advance notification of ballistic missile tests (under the 2005 Agreement on Pre-Notification of Flight Testing of Ballistic Missiles), exchange of lists of nuclear installations every year under the 1988 Agreement, and military-level communication to prevent accidental escalation.
• Strategic Stability: As nuclear neighbours, both countries must maintain effective communication channels, crisis management mechanisms and military restraint to avoid unintended escalation and preserve stability in South Asia.
• Strategic Significance for India:
  • Ensures security along India’s western frontier.
  • Deters cross-border aggression and terrorism.
  • Maintains strategic stability in South Asia.
  • Protects India’s sovereignty and territorial integrity.
  • Prevents escalation between two nuclear-armed states.

Trade, Connectivity & Humanitarian Relations

• Limited Bilateral Trade: India–Pakistan trade has declined drastically since 2019 due to political tensions and security concerns. At present, formal bilateral trade remains minimal, with limited essential goods moving through permitted channels and some trade taking place indirectly through third countries. This remains an important aspect of India Pakistan Relations.
• Connectivity: The Attari–Wagah Integrated Check Post (ICP) remains the principal land crossing between the two countries. However, cross-border transport and commercial connectivity remain highly restricted due to strained bilateral relations.
• Kartarpur Corridor: Opened in 2019, the Kartarpur Corridor allows Indian Sikh pilgrims to visit Gurdwara Darbar Sahib in Pakistan without a visa, making it one of the few functioning confidence-building measures between the two countries.
• Humanitarian Cooperation: Both countries periodically facilitate the release and repatriation of fishermen, civilian prisoners and inadvertent border crossers, besides providing consular access under bilateral agreements.
• Strategic Significance for India: Humanitarian and religious exchanges help maintain people-to-people contact, build mutual trust and preserve limited channels of engagement even during periods of political tension. These aspects are relevant for India Pakistan Relation BPSC Notes pdf.

Water Cooperation

• Indus Waters Treaty (IWT), 1960: The Indus Waters Treaty, signed on 19 September 1960 between Prime Minister Jawaharlal Nehru and President Ayub Khan, was brokered by the World Bank. It is regarded as one of the world’s most successful transboundary water-sharing agreements, having survived multiple wars and prolonged political tensions. The Treaty remains an important pillar of India Pakistan Relations.
• River Water Allocation:
  • Eastern Rivers (Ravi, Beas and Sutlej) were allocated for the exclusive use of India.
  • Western Rivers (Indus, Jhelum and Chenab) were allocated primarily to Pakistan, while India retained limited rights for domestic use, irrigation, navigation and run-of-the-river hydropower projects.

• Institutional Mechanism: The Treaty established the Permanent Indus Commission (PIC), comprising one Commissioner from each country, to exchange hydrological data, inspect projects and resolve technical issues. Disputes may be addressed through a Neutral Expert or a Court of Arbitration, depending on their nature.
• Major Disputes: Pakistan has objected to several Indian hydroelectric projects, including Kishanganga and Ratle, alleging violations of the Treaty. India maintains that these projects fully comply with the provisions of the IWT.
• Current Status: Following the Pahalgam terrorist attack (2025) and Operation Sindoor, India placed the Indus Waters Treaty in abeyance, stating that the decision would remain until Pakistan credibly and irrevocably ends support for cross-border terrorism. India has also reiterated that the Treaty remains in abeyance despite international legal proceedings.
• Strategic Significance for India:
  • Ensures sustainable management of the Indus River Basin.
  • Safeguards India’s legitimate rights over the eastern rivers.
  • Links water security with national security and cross-border terrorism.
  • Makes water cooperation a key strategic dimension of India–Pakistan relations and an important topic in India Pakistan Relation BPSC Notes pdf.

Regional & Multilateral Cooperation

• SAARC: India and Pakistan are founding members of SAARC. However, persistent bilateral tensions have largely stalled the organisation, with the SAARC Summit remaining suspended since 2016, limiting regional integration in South Asia.
• Shanghai Cooperation Organisation (SCO): Both countries became full members of the SCO in 2017. The organisation provides a platform for dialogue on regional security, counter-terrorism, connectivity and economic cooperation, despite bilateral differences.
• United Nations & FATF: India has consistently raised the issue of cross-border terrorism at the United Nations, while supporting international efforts through the Financial Action Task Force (FATF) to curb terror financing and money laundering.
• Strategic Significance for India: Multilateral forums provide opportunities to engage Pakistan diplomatically, address regional security concerns, strengthen counter-terrorism cooperation and promote stability in South Asia. These forums are an important dimension of India Pakistan Relations and are relevant for India Pakistan Relation BPSC Notes pdf.

4. Major Challenges in India–Pakistan Relations

Cross-Border Terrorism

• Greatest Challenge in Bilateral Relations: Cross-border terrorism remains the single biggest obstacle to normalising India–Pakistan relations. India has consistently maintained that terrorism and dialogue cannot go together and that meaningful bilateral engagement is possible only when Pakistan takes credible, verifiable and irreversible action against terrorist groups operating from its territory. India Pakistan Relations therefore remain strongly influenced by the issue of cross-border terrorism.
• India’s Allegation: India has repeatedly accused Pakistan of providing safe havens, financial support, training infrastructure and logistical assistance to terrorist organisations targeting India. Pakistan rejects these allegations, but India has consistently raised the issue in bilateral and international forums.
• Major Terrorist Organisations: Lashkar-e-Taiba (LeT), Jaish-e-Mohammed (JeM), Hizbul Mujahideen (HM)
• These organisations have been linked by India to several major terrorist attacks and many of their leaders are designated under the UN Security Council sanctions regime.
• Major Terrorist Attacks in India Attributed to Pakistan-based Groups:
  • 2001: Attack on the Indian Parliament.
  • 2008: Mumbai (26/11) Terror Attacks, resulting in 166 deaths.
  • 2016: Pathankot Air Force Station attack.
  • 2016: Uri Army Camp attack, leading to India’s Surgical Strikes across the LoC.
  • 2019: Pulwama Terror Attack, in which 40 CRPF personnel were killed, followed by India’s Balakot Air Strike.
  • 2025: Pahalgam Terror Attack, which prompted Operation Sindoor against terrorist infrastructure in Pakistan and Pakistan-occupied Kashmir.

Cross-Border Infiltration: Terrorist groups frequently attempt to infiltrate across the Line of Control (LoC) and the International Border using mountainous terrain, tunnels, drones and other means. India has strengthened border fencing, surveillance systems, anti-drone technology and intelligence-based operations to curb infiltration. This remains a major security challenge in India Pakistan Relations. India’s Counter-Terrorism Policy:

• Zero Tolerance towards Terrorism.
• Strong diplomatic efforts to isolate terrorism internationally.
• Modernisation of border management and intelligence systems.
• Use of precision military responses when necessary, including: Surgical Strikes (2016), Balakot Air Strike (2019), Operation Sindoor (2025).

International Cooperation: India has successfully mobilised international support against terrorism through forums such as the United Nations, Financial Action Task Force (FATF), G20, SCO and various bilateral partnerships. Pakistan’s placement on the FATF Grey List (2018–2022) increased international scrutiny of terror financing and anti-money laundering measures.

Impact on Bilateral Relations:

• Suspension of comprehensive dialogue.
• Sharp decline in trade and economic cooperation.
• Increased military deployment along the LoC.
• Diplomatic downgrading and restrictions on people-to-people exchanges.
• Growing strategic mistrust and recurring border tensions.

Strategic Significance for India:

• Protects India’s national security and territorial integrity.
• Safeguards peace and stability in Jammu & Kashmir.
• Prevents radicalisation and transnational terrorism.
• Strengthens India’s global leadership in the fight against terrorism.
• Reinforces the principle of zero tolerance towards terrorism as the foundation of India’s Pakistan policy and an important aspect of India Pakistan Relation BPSC Notes pdf.

Jammu & Kashmir Issue

• Historical Background: At the time of Partition in 1947, the princely state of Jammu & Kashmir had the option to join either India or Pakistan. Following the invasion by Pakistan-backed tribal militias in October 1947, Maharaja Hari Singh signed the Instrument of Accession on 26 October 1947, legally acceding the state to India. India subsequently deployed its armed forces, leading to the First Indo-Pak War (1947–48).
• United Nations Involvement: The conflict was referred to the United Nations Security Council (UNSC), which called for a ceasefire, the withdrawal of Pakistani forces and, subsequently, conditions for a plebiscite. Since the required preconditions, particularly Pakistan’s withdrawal, were never fulfilled, the plebiscite was never conducted.
• Line of Control (LoC): Following the Simla Agreement (1972), the earlier Ceasefire Line was redesignated as the Line of Control (LoC). Although it serves as the de facto military boundary, it is not an internationally recognised international border.
• India’s Position:
  • Jammu & Kashmir and Ladakh are integral and inalienable parts of India.
  • The issue is strictly bilateral and must be resolved in accordance with the Simla Agreement (1972) and the Lahore Declaration (1999).
  • India rejects any third-party mediation on the Kashmir issue.
  • The primary obstacle to normal relations is cross-border terrorism originating from Pakistan.

• Pakistan’s Position: Pakistan considers Jammu & Kashmir a disputed territory and advocates international involvement, including the role of the United Nations, while calling for a political resolution based on UNSC resolutions.
• Article 370 & Reorganisation (2019): On 5 August 2019, India abrogated Article 370 and Article 35A and reorganised the former state into the Union Territories of Jammu & Kashmir and Ladakh. India considers this an internal constitutional matter, whereas Pakistan strongly opposed the move and downgraded diplomatic and trade relations.
• Pakistan-Occupied Territories: India maintains that Pakistan-occupied Jammu & Kashmir (PoJK) and Gilgit-Baltistan are integral parts of India under illegal occupation by Pakistan. India has also objected to infrastructure projects under the China–Pakistan Economic Corridor (CPEC) passing through these territories, citing concerns over sovereignty and territorial integrity.
• Cross-Border Terrorism & Infiltration: India links the Kashmir issue with cross-border terrorism, infiltration across the LoC, drone-based smuggling of arms and narcotics, and the activities of Pakistan-based terrorist organisations. India maintains that ending terrorism is a prerequisite for improving bilateral relations.
• Confidence-Building Measures (CBMs): Over the years, both countries have undertaken measures such as the 2003/2021 ceasefire understandings, cross-LoC bus services, cross-LoC trade (currently suspended), DGMO-level talks and the Kartarpur Corridor to reduce tensions, though several initiatives have been affected by recurring security concerns.
• Strategic Significance for India:
  • Protects India’s sovereignty and territorial integrity.
  • Ensures security along the western frontier and the Line of Control (LoC).
  • Safeguards peace and development in Jammu & Kashmir and Ladakh.
  • Prevents cross-border terrorism and infiltration.
  • Remains central to India–Pakistan relations, South Asian security and stability in the Himalayan region.

India Pakistan Relations remain deeply influenced by the Jammu & Kashmir issue, making this section important for India Pakistan Relation BPSC Notes pdf.

Pakistan–China Strategic Nexus

• “All-Weather Strategic Cooperative Partnership”: China and Pakistan describe their relationship as an “All-Weather Strategic Cooperative Partnership”. Over the decades, cooperation has expanded from defence to economic, technological, nuclear, infrastructure and strategic domains, making it one of the strongest bilateral partnerships in Asia.
• Strategic Objective: For China, Pakistan provides direct access to the Arabian Sea and helps secure its western regions. For Pakistan, China is its largest strategic partner, supporting its military modernisation, infrastructure development and international diplomacy. From India’s perspective, this partnership creates the possibility of a two-front security challenge. This Pakistan–China nexus has significant implications for India Pakistan Relations.

A. China–Pakistan Economic Corridor (CPEC)

• Flagship BRI Project: The China–Pakistan Economic Corridor (CPEC) is the flagship project of China’s Belt and Road Initiative (BRI).
• Investment: Estimated investment of over US$60 billion.
• Route: Connects Kashgar (Xinjiang, China) to Gwadar Port (Balochistan, Pakistan) through highways, railways, energy projects, industrial parks and fibre-optic networks.
• Importance for China:
  • Provides direct access to the Arabian Sea.
  • Reduces dependence on the Malacca Strait.
  • Strengthens China’s energy security and western regional development.

CPEC is an important dimension of the Pakistan–China strategic nexus and has significant implications for India Pakistan Relations.

B. India’s Objection to CPEC

• A major portion of CPEC passes through Pakistan-Occupied Jammu & Kashmir (PoJK) and Gilgit-Baltistan, territories that India claims as its integral part.
• India has consistently opposed CPEC, arguing that it violates India’s sovereignty and territorial integrity.
• Consequently, India has not joined the Belt and Road Initiative (BRI).

India Pakistan Relations are also influenced by the strategic implications of CPEC and the wider Pakistan–China partnership. This is an important area for India Pakistan Relation BPSC Notes pdf.

C. Gwadar Port

• Gwadar Port is located on Pakistan’s Makran Coast near the Strait of Hormuz, one of the world’s most important energy chokepoints.
• Developed with Chinese assistance, Gwadar is expected to become a major commercial, logistics and energy hub.
• India is concerned that the port could eventually support Chinese naval logistics and military operations, increasing China’s strategic presence in the Arabian Sea.

Gwadar Port and the wider Pakistan–China strategic partnership have important implications for India Pakistan Relations and India’s strategic interests in the Indian Ocean Region.

D. Defence & Military Cooperation

• China is Pakistan’s largest supplier of defence equipment.
• Major areas of cooperation include: JF-17 Thunder fighter aircraft, J-10C fighter aircraft, Air defence systems, Naval frigates and submarines, Armed drones, Missile technology, Joint military exercises and defence production
• Regular military cooperation enhances Pakistan’s conventional military capabilities. India Pakistan Relations are significantly influenced by this growing Pakistan–China defence cooperation.

E. Nuclear & Missile Cooperation

• China has played an important role in Pakistan’s civilian nuclear energy programme, including the construction of nuclear power plants under IAEA safeguards.
• India has long expressed concerns regarding historical Chinese assistance to Pakistan’s nuclear and missile capabilities, viewing it as a factor affecting strategic stability in South Asia. This has important implications for India Pakistan Relations and is relevant for India Pakistan Relation BPSC Notes pdf.

F. Diplomatic Support

• China has frequently supported Pakistan on several international platforms.
• At the UN Security Council, China has occasionally blocked or delayed proposals related to the designation of certain Pakistan-based terrorist individuals until consensus was reached.
• China also advocates dialogue on regional issues while maintaining close political coordination with Pakistan. This diplomatic partnership has significant implications for India Pakistan Relations.

G. Economic & Technological Cooperation

• China is Pakistan’s largest trading partner and a major source of:
  • Infrastructure investment
  • Energy projects
  • Digital infrastructure
  • Telecommunications
  • Industrial parks
  • Mining and Special Economic Zones (SEZs)

This dimension of the Pakistan–China partnership is relevant to India Pakistan Relations and forms an important part of India Pakistan Relation BPSC Notes pdf.

H. Regional Security Implications

• The partnership significantly influences the strategic environment in South Asia, Central Asia and the Indian Ocean Region (IOR).
• Greater Chinese access to Pakistan’s ports and infrastructure has increased strategic competition in the Arabian Sea and the wider Indo-Pacific.
• The nexus also has implications for the security of Jammu & Kashmir, Ladakh and India’s western maritime approaches. These developments have a direct bearing on India Pakistan Relations and are important for India Pakistan Relation BPSC Notes pdf.

I. Challenges for India

• Possibility of a two-front security scenario involving China and Pakistan.
• Continued violation of India’s sovereignty through CPEC.
• Increased Chinese presence in the Arabian Sea and Indian Ocean Region.
• Enhanced military capability of Pakistan through Chinese defence cooperation.
• Greater geopolitical competition in South Asia and the Indo-Pacific.

These challenges remain significant considerations in shaping India Pakistan Relations.

J. India’s Response

• Strengthening border infrastructure and military preparedness along the northern and western frontiers.
• Developing strategic infrastructure in Jammu & Kashmir, Ladakh and the North-Western region.
• Expanding maritime capabilities through SAGAR/MAHASAGAR Vision, Mission-Based Deployments and enhanced naval presence in the Indian Ocean Region.
• Promoting alternative connectivity initiatives such as the India–Middle East–Europe Economic Corridor (IMEC), Chabahar Port (Iran) and the International North-South Transport Corridor (INSTC).
• Deepening strategic partnerships with countries such as the United States, France, Japan, Australia and ASEAN nations, while strengthening cooperation through the Quad and other Indo-Pacific initiatives.

These measures are important in shaping India’s strategic approach to India Pakistan Relations.

Strategic Significance for India

• Safeguarding India’s sovereignty and territorial integrity, particularly in PoJK and Ladakh.
• Preventing strategic encirclement in the Indian Ocean Region.
• Maintaining a favourable balance of power in South Asia.
• Protecting India’s maritime interests in the Arabian Sea and Indian Ocean.
• Strengthening India’s role as a leading power in the Indo-Pacific through enhanced connectivity, maritime security and strategic partnerships.

These strategic concerns are closely linked with India Pakistan Relations and are important for India Pakistan Relation BPSC Notes pdf.

Indus Waters Treaty Dispute

• Background: The Indus Waters Treaty (1960), brokered by the World Bank, governs the sharing of the Indus River System. While Ravi, Beas and Sutlej were allocated to India, Indus, Jhelum and Chenab were allocated primarily to Pakistan, with limited rights for India over the western rivers.
• Recent Dispute: Following the Pahalgam terrorist attack (2025) and Operation Sindoor, India placed the Indus Waters Treaty in abeyance, stating that normal implementation cannot continue until Pakistan credibly and irrevocably ends support for cross-border terrorism.
• Major Issues: Disputes over the Kishanganga and Ratle Hydroelectric Projects, differing interpretations of treaty provisions, and Pakistan’s objections to Indian projects have intensified bilateral tensions.
• Strategic Significance for India: The Treaty has become an important strategic lever linking water security, national security and cross-border terrorism, while safeguarding India’s legitimate rights over the Indus river system. The issue remains a significant component of India Pakistan Relations and is important for India Pakistan Relation BPSC Notes pdf.

Border Disputes, Border Tensions & Nuclear Arms Race

Complex Border Architecture: India and Pakistan share multiple sensitive border segments, including the International Border (IB), Line of Control (LoC), Actual Ground Position Line (AGPL) in Siachen Glacier, and the Sir Creek maritime boundary. These unresolved issues continue to generate military tensions and strategic mistrust. These issues remain central to India Pakistan Relations.

A. International Border (IB)

• The International Border extends from Gujarat to Jammu and is internationally recognised by both countries (except the Jammu & Kashmir sector).
• Although relatively peaceful compared to the LoC, incidents involving cross-border firing, infiltration, drone-based smuggling of arms, narcotics and counterfeit currency periodically occur. These challenges remain relevant to India Pakistan Relations.

B. Line of Control (LoC)

• The Line of Control (LoC) extends for about 740 km from Jammu to NJ9842 in Ladakh.
• It was established under the Simla Agreement (1972) after the 1971 war.
• It remains the most militarised and volatile sector of India–Pakistan relations.
• Major challenges include:
  • Cross-border infiltration.
  • Ceasefire violations.
  • Terrorist launch pads across the LoC.
  • Drone-based delivery of weapons and narcotics.
• The 2021 DGMO ceasefire understanding significantly reduced ceasefire violations, although infiltration attempts continue.

C. Siachen Glacier (AGPL)

• Siachen Glacier, located in the Eastern Karakoram, is known as the highest battlefield in the world.
• The dispute originates from differing interpretations of the boundary beyond NJ9842, where the Karachi Agreement (1949) and Simla Agreement (1972) left the alignment undefined.
• Since Operation Meghdoot (1984), India has maintained control over the strategically important Saltoro Ridge, while Pakistan occupies positions west of it.
• Challenges include: Extremely harsh climatic conditions, High financial and logistical costs and Frequent casualties due to avalanches and weather rather than combat.
• For India, retaining the Saltoro Ridge is critical because it overlooks approaches linking Pakistan-occupied Kashmir (PoJK) and China-controlled territory, thereby preventing potential strategic connectivity between the two. This remains an important strategic dimension of India Pakistan Relations and a relevant topic for India Pakistan Relation BPSC Notes pdf.

D. Sir Creek Dispute

• Sir Creek is a 96-km tidal estuary located between Gujarat (India) and Sindh (Pakistan) in the Rann of Kutch.
• The dispute concerns the exact alignment of the maritime boundary:
  • India supports the mid-channel (thalweg) principle.
  • Pakistan claims the eastern bank as the boundary.
• Resolution of the dispute would determine:
  • Maritime boundary in the Arabian Sea.
  • Exclusive Economic Zone (EEZ).
  • Continental Shelf rights.
  • Fishing rights and offshore resource exploration.

The Sir Creek dispute remains an important component of India Pakistan Relations.

E. Maritime Security Challenges

• The Arabian Sea remains vulnerable to:
  • Illegal fishing.
  • Drug trafficking.
  • Arms smuggling.
  • Maritime terrorism.
  • Arrest of fishermen crossing the maritime boundary inadvertently.
• India and Pakistan periodically exchange detained fishermen through humanitarian mechanisms.

F. Nuclear Arms Race

• Both countries conducted nuclear tests in 1998, making South Asia a nuclearised region.
• India follows the doctrine of No First Use (NFU) and maintains credible minimum deterrence.
• Pakistan does not have a declared No First Use policy and emphasises full-spectrum deterrence, including tactical nuclear weapons.
• Continuous development of ballistic missiles, cruise missiles, air defence systems and delivery platforms has intensified the strategic competition.

These security and strategic dimensions are central to India Pakistan Relations and are important for India Pakistan Relation BPSC Notes pdf.

G. Confidence Building Measures (CBMs)

• DGMO Hotline.
• 2021 Ceasefire Understanding.
• 1988 Agreement on Non-Attack on Nuclear Installations, under which both countries exchange the list of nuclear facilities every year on 1 January.
• 2005 Agreement on Pre-Notification of Flight Testing of Ballistic Missiles.
• Military flag meetings and border communication mechanisms.

These confidence-building measures remain important for managing tensions and maintaining strategic stability in India Pakistan Relations.

Strategic Significance for India

• Protects India’s territorial integrity and sovereignty.
• Secures the western frontier, Jammu & Kashmir, Ladakh and the Arabian Sea.
• Prevents cross-border terrorism and infiltration.
• Ensures credible nuclear deterrence and strategic stability.
• Strengthens India’s national security while reducing the risk of accidental military escalation between two nuclear-armed neighbours.

These priorities are central to India Pakistan Relations and important for India Pakistan Relation BPSC Notes pdf.

6. Significance of Pakistan for India

• Immediate Western Neighbour: Pakistan shares a 3,323 km international border and the Line of Control (LoC) with India, making it central to India’s national security, border management and foreign policy.
• Security of India’s Western Frontier: Peace and stability along the International Border, Line of Control (LoC) and Siachen Glacier are essential for preventing cross-border terrorism, infiltration, ceasefire violations and military escalation.
• Counter-Terrorism: Pakistan’s role in addressing cross-border terrorism, terror financing and extremist networks is crucial for India’s internal security and regional stability.
• Jammu & Kashmir: The Jammu & Kashmir issue remains the most significant bilateral dispute, directly affecting national security, border stability and diplomatic relations.
• Water Security: Pakistan is a lower riparian state in the Indus River System. The Indus Waters Treaty (1960) makes water cooperation an important dimension of bilateral relations, linking water security with strategic security.
• Nuclear Stability in South Asia: As two nuclear-armed neighbours, India and Pakistan must maintain credible deterrence, effective communication mechanisms and crisis management to avoid unintended escalation.
• Regional Peace & SAARC: Stable India–Pakistan relations are essential for the effective functioning of SAARC, regional economic integration and greater cooperation in trade, connectivity, energy and climate change.
• Gateway to Central Asia (Long-term Potential): Improved relations could facilitate overland connectivity to Afghanistan and Central Asia, enhancing India’s access to energy resources and regional markets.
• Countering the Pakistan–China Nexus: Pakistan’s strategic partnership with China, including CPEC and Gwadar Port, has significant implications for India’s security. Strong diplomatic, economic and strategic engagement is necessary to safeguard India’s interests in South Asia and the Indian Ocean Region.
• Strategic Significance for India’s Rise: Peaceful and stable relations with Pakistan would enable India to focus greater resources on economic growth, regional connectivity and global leadership, while reducing the costs associated with prolonged military tensions on the western frontier.

Understanding the significance of Pakistan is essential for a comprehensive study of India Pakistan Relations and for India Pakistan Relation BPSC Notes pdf.

8. Conclusion

India–Pakistan relations remain one of the most challenging bilateral relationships in the world, shaped by historical conflicts, the Jammu & Kashmir issue, cross-border terrorism, the Indus Waters Treaty and strategic competition. While both countries share common interests in regional peace, stability and economic development, progress depends on building mutual trust and addressing security concerns. India’s consistent position remains that terrorism and dialogue cannot go together, and any meaningful improvement in bilateral relations requires credible and irreversible action against cross-border terrorism. At the same time, maintaining ceasefire mechanisms, humanitarian exchanges and diplomatic channels is essential to prevent escalation between two nuclear-armed neighbours and to ensure long-term peace and stability in South Asia. India Pakistan Relations therefore remain a crucial topic for understanding India’s foreign policy and regional security.
