Introduction: Post-Galwan Border Patrolling Surge

The 2020 Galwan Valley clash on June 15 marked a critical escalation in India-China border tensions along the Line of Actual Control (LAC) in Ladakh. Following this violent encounter, Indian security forces significantly increased patrolling frequency and troop deployments along the LAC. Data from the Indian Army and Ministry of Defence (MoD) reveal a 40% rise in patrolling frequency and a 30% increase in troop strength between 2020 and 2023. This shift signals a strategic emphasis on enhanced surveillance and deterrence to prevent future incursions.

Constitutional and Legal Framework Governing Border Security

Article 355 of the Constitution of India mandates the Union to protect states against external aggression and internal disturbances, providing the constitutional basis for border security operations. The Armed Forces Special Powers Act (AFSPA), 1958, particularly Sections 4 and 5, empowers armed forces to operate in disturbed border areas, including the LAC sectors. The Border Security Force Act, 1968 governs the BSF’s role in border management, although the Indian Army remains the primary force along the India-China border. The Supreme Court’s ruling in Union of India v. Raghunath Thakur (2018) reaffirmed the central government’s exclusive prerogative in matters of border security and defence preparedness.

• Article 355: Union’s duty to protect states from external aggression
• AFSPA Sections 4 & 5: Special powers to armed forces in disturbed areas
• Border Security Force Act, 1968: Legal framework for BSF operations
• Union of India v. Raghunath Thakur: Central government’s authority on border security

Operational and Economic Dimensions of Increased Patrolling

Post-Galwan, the Ministry of Defence increased border infrastructure budget by approximately 15% in 2021-22, reaching ₹5.25 lakh crore (Economic Survey 2022-23). Enhanced patrolling and troop deployments have raised annual operational costs by an estimated ₹1,200 crore. Infrastructure development accelerated, with ₹13,000 crore sanctioned for roads and bridges along the LAC, facilitating rapid troop movement and logistics. Despite heightened tensions, India-China bilateral trade remained robust at $125 billion in 2021, indicating economic interdependence amid security challenges.

• Defence budget for border infrastructure rose from ₹4.5 lakh crore (2019-20) to ₹5.25 lakh crore (2021-22)
• Annual operational cost increase: ₹1,200 crore due to intensified patrolling
• ₹13,000 crore allocated for LAC roads and bridges (NITI Aayog, 2023)
• India-China bilateral trade at $125 billion in 2021 despite border tensions

Key Institutions and Their Roles in Border Management

The Indian Army leads patrolling and securing the LAC, supported by the Border Roads Organisation (BRO) responsible for infrastructure development. The Ministry of Defence (MoD) formulates policy and allocates budgets, while the Ministry of External Affairs (MEA) manages diplomatic engagement with China. The Border Security Force (BSF) assists in certain sectors, although its role along the LAC is limited compared to the India-Pakistan border. Intelligence gathering and analysis are conducted by the Research and Analysis Wing (RAW), crucial for anticipating Chinese troop movements and intentions.

• Indian Army: Primary force for LAC patrolling and security
• BRO: Infrastructure development along border areas
• MoD: Policy and budgetary authority
• MEA: Diplomatic engagement with China
• BSF: Support role in border management
• RAW: Intelligence on border activities

Quantitative Shifts in Border Security Post-Galwan

Comparative Analysis: India-China vs Other Border Management Models

China’s border management along the India-Bhutan border is less intensive, relying on bilateral agreements and established protocols, contrasting with the high-tension LAC sectors. The United States increased patrolling and infrastructure development along the US-Mexico border post-2018, resulting in a 25% reduction in illegal crossings (US Customs and Border Protection, 2022). This illustrates that while increased patrolling can deter incursions, it also raises operational costs and may exacerbate diplomatic tensions.

Critical Gaps in India’s Border Management Strategy

Despite increased patrolling and infrastructure, India lacks an integrated border management system that combines real-time surveillance, rapid deployment, and diplomatic crisis protocols. Current responses remain largely reactive, with limited use of advanced technologies such as AI-enabled monitoring or unified command centers. This gap undermines proactive threat anticipation and coordinated civil-military responses, increasing vulnerability to sudden escalations.

• Absence of comprehensive integrated border management system
• Limited real-time surveillance and rapid deployment capabilities
• Reactive rather than proactive response to border incidents
• Need for enhanced civil-military coordination and diplomatic crisis management

Significance and Way Forward

The post-Galwan increase in patrolling reflects a strategic recalibration prioritizing deterrence and infrastructure readiness. Sustained investment in roads, bridges, and forward posts enhances operational mobility. However, addressing the critical gaps requires adopting integrated technologies, improving intelligence sharing, and streamlining civil-military coordination. Diplomatic engagement must continue alongside military preparedness to prevent escalation and seek long-term resolution.

• Continue expanding infrastructure to support rapid troop movement
• Develop integrated border management systems with real-time surveillance
• Enhance intelligence and civil-military coordination mechanisms
• Maintain diplomatic dialogue to reduce tensions and resolve disputes
