The Great Nicobar Island development project has taken on heightened strategic importance following the Iran war, with the Strait of Malacca — the world's second-largest oil trade chokepoint after the Strait of Hormuz — continuing to serve as the primary artery for East Asia's energy and economic flows, according to a report by Canada-based Geopolitical Monitor. The project is assessed to significantly reinforce India's strategic posture at the gateway of the Malacca Strait.

The Malacca Dilemma and China's Countermoves

The report identifies the so-called 'Malacca Dilemma' as a long-standing anxiety for Chinese strategic planners. Beijing has responded by pursuing alternative connectivity corridors — notably the China-Pakistan Economic Corridor (CPEC) and the China-Myanmar Economic Corridor (CMEC) — to reduce its dependence on the Malacca chokepoint and secure independent access to the Indian Ocean.

The report further notes that China represents a structural challenge for India owing to the unresolved boundary dispute, and that the broader strategic pressure from Beijing continues to intensify despite a recent thaw in bilateral relations.

What the Great Nicobar Project Delivers Strategically

According to the Geopolitical Monitor assessment, the project will substantially expand New Delhi's capacity to monitor the Strait of Malacca and project power into the wider Indo-Pacific region. The report draws a direct parallel with Iran's use of geography as a strategic instrument, suggesting India could similarly leverage Great Nicobar in any contingency scenario.

'The project will expand New Delhi's strategic reach deep into Southeast Asia, serving as a forward operating base for India's greater military presence in the Indo-Pacific region,' the report stated.

Notably, the report contextualises this within established precedent: Britain and the United States jointly operate Diego Garcia; France maintains military bases in the Southwest Indian Ocean; and Australia holds the Christmas and Cocos Islands. The report argues that Great Nicobar would simply join this established network of island-based military installations.

Infrastructure Scope and Timeline

Located at the southern tip of the Andaman and Nicobar island chain — positioned between Myanmar and Indonesia — Great Nicobar sits in close proximity to the Malacca Strait. The project integrates port development, civilian infrastructure, and strategic military objectives across three phases, with a projected completion date of 2047 and an estimated cost of $9–11 billion.

Planned infrastructure includes a trans-shipment hub, a civil and military airport, gas and solar power plants, and a new township. The Andaman and Nicobar Islands already host a tri-service military command; the new facilities are expected to add a durable additional layer to those existing capabilities.

Economic Rationale: Breaking Port Dependence

Beyond its military dimensions, the report underscores the project's economic logic. The trans-shipment hub is specifically aimed at reducing India's reliance on major regional deep-water ports such as Colombo and Singapore — a dependence that carries both commercial and strategic vulnerability. This dual-use character, the report argues, gives the project significance well beyond a purely military footprint.

As India advances the project through its phased timeline toward 2047, its ability to shape Indo-Pacific maritime dynamics — and complicate China's Malacca calculus — is expected to grow considerably.
