Race to Indian Ocean Region

An extensive analysis focused on the Indian Ocean Region (IOR) conducted with the benefit of nearly four months of hindsight, allowing for a detailed examination of the events and their alignment with subsequent developments. The post explores the evolving strategic landscape of the IOR, covering all dimensions: geopolitical, military, economic and environmental.

What is IOR?

This region, encompassing critical maritime routes and chokepoints, is framed as a theater of intense competition among global powers, with a particular focus on India’s role, the significance of Diego Garcia, and the shifting dynamics involving the United States, China, Turkey, and regional actors like Indonesia and Sri Lanka.

Race to IOR

September 2025, started with a series of quick updates from August 2025 about specific IOR locations - Chennai, Vladivostok, Malacca, Sunda, Andaman & Nicobar / Diglipur. Suggesting a reconfiguration of maritime routes and strategic priorities. The Indian Navy’s emerging role, the vulnerability of traditional chokepoints like Malacca and Sunda and the heightened significance of India’s Andaman & Nicobar Islands. Delved into the geopolitical implications of Diego Garcia, the return of Chagos to Mauritius, and the potential for a two-front war involving the US (directly or indirectly) in the IOR and Pacific Ocean. The narrative is enriched with maps, references to historical posts, and speculative insights into U.S. and Indian strategies, making it a comprehensive, if opinionated, analysis of IOR dynamics.

Detailed Analysis of Key Dimensions

Geopolitical & Military Dimension

The Chennai-Vladivostok route, part of India-Russia maritime cooperation, has become unsafe, signaling disruptions in Indo-Pacific connectivity. This is attributed to rising tensions and the shifting allegiances of regional players. The mention of Indonesia as India’s Guest of Honor for Republic Day 2025 hints at a strengthening partnership, potentially countering China’s influence in the Malacca Strait, a chokepoint handling over 40% of global trade.

One can expect that Malacca and Sunda will fall out of favor, with Sunda (between Java and Sumatra) emerging as a new focal point due to its strategic depth and lesser congestion.

A recurring theme during the analysis, is the significance of Diego Garcia, a USoA military base in the Chagos Archipelago (Mauritius), described as midway between Guam and the IOR’s western approaches. Its control is a linchpin in USoA strategy.

With Maldives acquiring Turkish drones and Sri Lanka poised to soon follow & fall in USoA trap in some form or the other, indicating a broadening of influence by non-traditional IOR powers.

On Chagos itself: The return of Chagos to Mauritius, formalized in 2025 after decades of dispute, is portrayed as a setback for the USoA and UK. This prompted a series of chaos. Starting with Sri Lanka (2022) and Bangladesh (2024) as compensatory moves. This aligns with Foreign Policy’s 2024 article, which notes Diego Garcia’s role in USoA Indo-Pacific goals and the sovereignty debate’s impact on international legitimacy.

Another achilles heel is India’s Great Nicobar Project in Andaman & Nicobar Islands, are elevated to a central role, with Diglipur flagged for increased activity. This reflects India’s SAGAR (Security and Growth for All in the Region) initiative, aimed at ensuring a free and open IOR.

Since 2022 warnings were put out about Southern IOR vulnerabilities, underscoring a long-term perspective, validated by the current focus on these islands as a counter to Chinese encirclement via the String of Pearls.

The military narrative is prominent, with “Indian Navy would do the opening” by Indian Defence Minister declared if Pakistan doesn't mend its ways. This suggests a proactive stance, potentially crippling key routes towards Pakistan.

Maldives and Sri Lanka acquired drones from Turkey points to an arms race, with implications for IOR stability.

Diego Garcia’s strategic position & security of the route to Guam via Sunda Strait reinforces its military significance, hinting at U.S. concerns over losing Malacca as a secure corridor to India.

A two-front war for the USoA, one in the IOR and another in the Pacific is a strategic overstretch. With Somalian bases potentially activated to cover the western IOR.

India's proximity to Sri Lanka, where Turkish drone deployments could challenge Indian naval dominance. Japan’s visit cancellation and USoA-Japan ADB moves on CPEC (China-Pakistan Economic Corridor) suggests a complex military-diplomatic interplay, with India possibly ahead in the game.

Economic Dimension

Economically, it is the IOR’s role in global trade, with the Chennai-Vladivostok route’s insecurity threatening India-Russia energy and goods flows. The shift from Malacca to Sunda is framed as an economic necessity, with Singapore’s position as the last post between Malacca and Guam under scrutiny.

A potential base in Somaliland is seen as a trade boon, enhancing access to African markets and countering China’s Djibouti base. Will India be able to operate from / to there, is something that remains to be seen.

Adani’s ouster from Australia’s Abbot Point ties into economic rivalry, with Chinese presence near this port adding pressure.

The Mauritius and Chagos development plans signal economic cooperation, with India’s $25 million assistance boosting Port Louis and Chagos Marine Protected Area, aligning with SAGAR’s economic goals.

Environmental Dimension

While less emphasized, environmental concerns emerge in the context of Chagos’ return to Mauritius, with the establishment of a Marine Protected Area, it reflects growing IOR focus on sustainability, as highlighted in the University of Melbourne’s 2021 report on environmental dynamics.

Green checkpoints in Andaman & Nicobar, Muscat, and Seychelles need environmental monitoring as part of India’s IOR strategy, countering overfishing and pollution from rival powers.

Contextual Developments and Validation

Since August 31, 2025, several of these have materialised. The Indian Navy’s increased patrols in the Andaman Sea, reported by The Hindu on September 15, 2025, align with the “opening” claim.

Indonesia’s enhanced maritime cooperation with India, following Republic Day 2025, was covered by Reuters on January 28, 2025, supporting the guest of honour narrative.

The U.S. activation of a Somali base, as noted by Al Jazeera on October 10, 2025, corroborates the thread’s foresight on western IOR militarisation.

For now, the two-front war remains speculative, though USoA-China tensions in the South China Sea suggest plausibility.

IOR can hence be called as “Kurukshetra south of Kanyakumari” is not exaggerated. A RUSI’s Indo-Pacific brief validates India’s naval buildup but cautions against overestimating USoA decline in Malacca.

Conclusion

A multifaceted exploration of the IOR, spanning geopolitical shifts, military strategies, economic stakes, and environmental considerations.This analysis captures the vision of a contested IOR, India’s rising role, and the pivotal status of Diego Garcia, while acknowledging its speculative edges and aligning it with verified developments.

We will cover Somaliland updates in a separate post.
