Why Great Nicobar Could Become India's Most Strategic Island Against China

At

first glance, Great Nicobar Island appears to be a remote and sparsely populated corner of India. Located nearly 1,600 kilometres from the mainland, it is actually closer to the coasts of Thailand, Malaysia and Indonesia than to the Indian heartland. Yet its geography places it at the centre of one of the world's most important maritime corridors.The Narendra Modi government has approved an ambitious $11 billion infrastructure plan that includes a transhipment port, a dual-use civilian-military airport, a power plant, tourism infrastructure and an entirely new township. Initially pitched as an economic project, the development is increasingly being viewed through the prism of India's strategic competition with China.

India's Watchtower Over The Strait Of Malacca

Great Nicobar sits near the western entrance to the Strait of Malacca, a narrow waterway that carries roughly one-third of global maritime trade and a significant share of the world's seaborne oil shipments. More importantly, around 80 per cent of China's crude oil imports and nearly two-thirds of its trade transit through this route.Former Indian Navy Vice Chief Admiral Shekhar Sinha has described the island as an ideal location to monitor shipping activity entering and exiting the strait. Enhanced surveillance and maritime domain awareness from Great Nicobar could provide India with valuable intelligence on commercial and military movements across the Indo-Pacific.The strategic value of the island has become even more apparent amid growing global concerns over critical chokepoints such as the Strait of Hormuz and the South China Sea. Defence planners increasingly see Great Nicobar as an asset that could strengthen India's position in any future regional contingency involving China.

Development Versus Conservation

While the strategic rationale has gained momentum, the project remains deeply controversial. Nearly 166 square kilometres of land have been earmarked for development, with a significant portion overlapping tribal reserve areas inhabited by the indigenous Shompen community.Environmental experts have warned that almost one million trees may need to be cleared, while activists argue that the large-scale infrastructure push could irreversibly damage one of India's richest island ecosystems. The region is also classified as Seismic Zone V, the country's highest earthquake-risk category, raising additional concerns over major construction activity.Critics, including opposition leaders and conservation groups, argue that the project prioritises geopolitics over ecological and cultural preservation. The government, however, maintains that the initiative will strengthen national security, improve connectivity and establish India as a more influential player in the Indo-Pacific.For New Delhi, Great Nicobar represents far more than an isolated island. It is increasingly being viewed as a strategic outpost that could shape India's maritime posture for decades to come, even as the debate over its future continues.
