Indian Prime Minister Narendra Modi has repeatedly stressed that the Indo-Pacific must remain “free, open and inclusive.” Increasingly, India’s eastern seaboard is becoming the central pillar of that vision, transforming from a largely economic coastline into a critical geopolitical and maritime frontier.
Stretching from West Bengal through Odisha and Andhra Pradesh to Tamil Nadu, and extending deep into the Bay of Bengal via the Andaman & Nicobar Islands, India’s eastern arc now sits at the convergence of trade routes, military competition, and emerging security threats. Strategic planners in New Delhi increasingly view this region not merely as a coastal belt, but as the operational heart of India’s Indo-Pacific engagement.
This shift in strategic thinking is being driven by multiple factors. India’s traditional security orientation has long focused on its western borders. However, geopolitical developments across the Indo-Pacific are compelling New Delhi to recalibrate its national security doctrine toward the east.
Recent remarks by Pakistan Army Chief Field Marshal Asim Munir suggesting that future strategic pressure points could emerge along India’s eastern seaboard reflect growing recognition of India’s maritime vulnerabilities. While India’s western frontier remains sensitive, the maritime domain is increasingly becoming the arena where future power competition may unfold.
Yet the more consequential strategic challenge comes from China.
Beijing’s long-term vision of connecting China’s Yunnan province to the Bay of Bengal through Myanmar represents a sophisticated continental-maritime strategy designed to expand Chinese influence into the eastern Indian Ocean. Infrastructure projects, transport corridors, pipelines, and port access arrangements in Myanmar could eventually provide China with dual-use logistical capabilities, enabling both commercial and strategic reach.
For India, this raises significant concerns. Chinese access to the Bay of Bengal would alter the regional balance of power and potentially challenge India’s maritime dominance in its immediate neighborhood.
At present, however, prolonged civil conflict and instability within Myanmar have delayed the full operationalization of these Chinese ambitions. Ironically, this instability has created strategic breathing room for India. New Delhi now has a valuable opportunity to strengthen its eastern defenses, expand regional partnerships, and accelerate infrastructure development before China consolidates its position.
India’s East Coast has consequently emerged as a primary strategic frontier. It anchors access to the Bay of Bengal, hosts major industrial and maritime infrastructure, and serves as India’s gateway to Southeast Asia under the Act East policy.
History demonstrates that maritime power is indispensable to global influence. The renowned American naval strategist Alfred Thayer Mahan famously observed that “control of the Indian Ocean shapes the balance of power in Asia.” His assessment remains deeply relevant in today’s geopolitical environment.
Similarly, Admiral John C. Aquilino, who served as Commander of U.S. Indo-Pacific Command from 2021 to 2024, described the Indo-Pacific as the theatre where the future of the international order will be decided.
For India, the Andaman & Nicobar Islands occupy the center of this evolving strategic framework. Located close to the Strait of Malacca — one of the world’s busiest and most vital maritime chokepoints — the islands provide India with a unique geostrategic advantage.
The Strait of Malacca carries a substantial portion of global trade and energy shipments linking the Indian and Pacific Oceans. Any disruption there would have global economic consequences. Singapore Prime Minister Lawrence Wong has repeatedly emphasized that the openness and stability of Malacca are indispensable for international commerce and regional security.
This reality places the Andaman & Nicobar Islands at the frontline of India’s maritime strategy.
India’s maritime doctrine already recognizes that secure seas are essential for economic prosperity and strategic autonomy. Consequently, defense analysts argue that the Andaman & Nicobar Command must evolve into a fully integrated forward-operating military hub — effectively functioning as an “unsinkable aircraft carrier” in the eastern Indian Ocean.
Such a transformation would require enhanced naval infrastructure, air defense systems, surveillance capabilities, logistics networks, and maritime domain awareness architecture. It would also strengthen India’s ability to monitor critical sea lanes and respond rapidly to regional contingencies.
India’s growing focus on the East Coast is also tied to concerns over economic resilience.
The country remains heavily dependent on energy flows through the Strait of Hormuz, leaving it vulnerable to instability in the Gulf region. Ongoing tensions involving Iran have once again highlighted how disruptions in West Asian maritime routes can immediately affect India’s economy.
If Hormuz symbolizes India’s long-standing strategic vulnerability, Malacca represents a strategic opportunity.
By strengthening the East Coast and deepening its Bay of Bengal engagement, India can diversify trade networks, reduce logistical concentration risks, and build greater resilience into its economy and supply chains.
The eastern seaboard is increasingly emerging as an economic powerhouse. Major ports, industrial corridors, logistics hubs, and manufacturing clusters are transforming the coastline into a vital engine of national growth. Policymakers now argue that this infrastructural expansion must be viewed not only through an economic lens, but also through a strategic one.
External Affairs Minister S. Jaishankar has consistently argued that modern connectivity is no longer just about commerce; it is equally about trust, resilience, and strategic autonomy. In this framework, ports, industrial corridors, and digital infrastructure must be designed to withstand geopolitical shocks and supply chain disruptions.
Security threats facing the East Coast are also evolving beyond conventional military risks.
Cyberattacks targeting port infrastructure, vulnerabilities in digital logistics systems, climate-related coastal disruptions, and fragile supply chains are now integral components of national security planning. Rising sea levels and extreme weather events in the Bay of Bengal further increase the strategic importance of resilient coastal infrastructure.
Regional cooperation frameworks led by Association of Southeast Asian Nations also emphasize maritime security, connectivity, disaster management, and sustainable development, aligning closely with India’s Indo-Pacific objectives.
Another important dimension of India’s eastern strategy involves building networks with trusted international partners.
The Quadrilateral Security Dialogue — commonly known as the QUAD — has emerged as a natural platform for cooperation. Increasingly, however, its significance extends beyond traditional military balancing and into non-traditional security domains such as resilient supply chains, critical technologies, maritime awareness, cybersecurity, and humanitarian assistance.
As India prepares for upcoming high-level diplomatic engagements, including the anticipated visit of U.S. Secretary of State Marco Rubio, discussions are expected to focus heavily on maritime coordination, technology partnerships, disaster response mechanisms, and Indo-Pacific resilience.
Beyond the QUAD, India is also seeking to align a broader coalition of like-minded partners with its East Coast strategy.
Countries such as Japan and South Korea bring advanced technology and investment capabilities. Vietnam offers growing maritime convergence with India in the South China Sea and Bay of Bengal region. Meanwhile, Taiwan is increasingly viewed as a critical partner in semiconductors and advanced manufacturing supply chains.
India’s maritime neighborhood remains equally significant.
Countries such as Sri Lanka, Maldives, Mauritius, and Seychelles continue to occupy central positions within India’s SAGAR vision — Security and Growth for All in the Region. Cooperation in coastal surveillance, maritime capacity building, and disaster response has become increasingly important.
Further east, India’s outreach to Papua New Guinea, Fiji, and Timor-Leste signals a gradual but deliberate expansion of India’s Indo-Pacific footprint.
Looking ahead, three major trends are likely to shape the trajectory of India’s East Coast strategy.
First, maritime competition in the Bay of Bengal is expected to intensify as regional and extra-regional powers seek influence over trade routes and strategic infrastructure.
Second, the Andaman & Nicobar Islands are likely to emerge as India’s most decisive strategic lever in the Indo-Pacific, particularly in relation to maritime surveillance and chokepoint control.
Third, economic corridors and connectivity projects will increasingly acquire dual strategic and security functions, blurring the line between commercial infrastructure and geopolitical assets.
India’s maritime history provides important context for this transformation. From ancient trade networks to cultural exchanges across Southeast Asia, India historically projected influence through maritime connectivity rather than territorial expansion. Today, New Delhi appears determined to revive that maritime orientation within a modern strategic framework.
A reimagined East Coast Economic Community — anchored in economic dynamism, strategic foresight, and resilient infrastructure — could become the cornerstone of India’s Indo-Pacific future.
By developing world-class ports, expanding coastal infrastructure, improving maritime surveillance, strengthening naval capabilities, and deepening partnerships with trusted countries, India can transform its eastern seaboard into one of the defining strategic regions.
