From Sabang to Great Nicobar: The 710 Kilometres that could redraw Asia's maritime map

From Sabang to Great Nicobar: The 710 Kilometres that could redraw Asia's maritime map

Part 1: Why the world's most important shipping story isn't making headlines

For decades, global attention has focused on the Strait of Hormuz whenever oil prices surged or geopolitical tensions escalated. A single incident in the Gulf can send crude prices soaring and disrupt global energy markets overnight. Yet, another maritime corridor—thousands of kilometres to the east—quietly carries a far broader mix of global commerce every single day. The Strait of Malacca, wedged between Indonesia, Malaysia and Singapore, has become the backbone of modern supply chains, connecting the factories of East Asia with the markets of Europe, the Middle East and Africa. From smartphones assembled in China and semiconductors manufactured in Taiwan to automobiles from Japan, garments from Vietnam and crude oil bound for Asian refineries, an extraordinary volume of world trade depends on this narrow waterway remaining open.

More than 90,000 commercial vessels transit the Strait of Malacca every year, making it one of the busiest shipping lanes on the planet. According to international maritime estimates, nearly one-quarter to one-third of global maritime trade passes through this corridor, while around 15–16 million barrels of crude oil and petroleum products move through it daily. It is also the primary route for liquefied natural gas (LNG) shipments destined for Japan, South Korea and China. Any prolonged disruption—whether caused by piracy, an accident, military conflict or natural disaster—would force vessels to divert through the longer Lombok or Sunda Straits, adding several days to voyages, increasing bunker fuel consumption, freight costs and insurance premiums. For shipping lines operating on tight schedules, time lost at sea quickly translates into higher costs across global supply chains.

This is precisely why a seemingly modest stretch of water—roughly 710 kilometres separating Indonesia's Sabang Port from India's Great Nicobar Island—is attracting growing strategic attention. At first glance, these are two remote locations on opposite sides of the Andaman Sea. But viewed through the lens of maritime logistics, they occupy one of the most valuable positions in global commerce: the western gateway to the Strait of Malacca. Together, they overlook the entrance through which thousands of merchant ships pass before continuing towards Singapore, East Asia or the Pacific. Geography has quietly placed India and Indonesia at the doorstep of one of the world's greatest economic arteries.

Until recently, discussions around this region were largely confined to naval strategy and regional security. Today, the conversation is changing. The focus is no longer just on protecting sea lanes—it is increasingly about building resilient maritime infrastructure, improving port connectivity, creating alternative transshipment hubs, enhancing search and rescue capabilities, supporting ship repair and bunkering services, and strengthening supply chains that have become vulnerable to geopolitical shocks. As companies diversify manufacturing beyond China and governments invest in more secure logistics networks, the eastern Indian Ocean is emerging as one of the most closely watched maritime theatres of the twenty-first century.

India and Indonesia recognise this shift. During recent high-level meetings, both governments reaffirmed their commitment to expanding cooperation in maritime security, the blue economy, defence, digital connectivity and port-led development. These discussions build upon the 2018 Shared Vision of India–Indonesia Maritime Cooperation in the Indo-Pacific, which identified freedom of navigation, maritime connectivity, sustainable use of marine resources and closer coordination between the two countries as common priorities. While defence cooperation often captures headlines, the long-term significance lies elsewhere: in creating a maritime ecosystem capable of supporting the next generation of Indo-Pacific trade.

The timing could hardly be more significant. Global shipping is navigating one of its most challenging periods in decades. Attacks on commercial vessels in the Red Sea have forced many shipping lines to reroute around the Cape of Good Hope, increasing transit times between Asia and Europe by up to two weeks. Congestion at major ports, geopolitical tensions in the South China Sea and climate-related disruptions have further exposed the fragility of global logistics networks. In response, governments and shipping companies are no longer evaluating ports solely on cargo-handling capacity; they are looking for strategic locations that can improve resilience, reduce dependence on single gateways and provide operational flexibility during crises.

Against this backdrop, India's Great Nicobar Transshipment Port Project and Indonesia's Sabang Port are increasingly viewed as complementary rather than isolated developments. Great Nicobar aims to position India as a major transshipment hub capable of handling some of the world's largest container vessels, reducing dependence on foreign ports such as Singapore, Colombo and Port Klang. Sabang, situated at the northern tip of Sumatra, offers deep-water access close to one of the busiest sea lanes in the world. Together, they present an opportunity to create a logistics corridor that extends beyond bilateral trade and contributes to the broader resilience of Indo-Pacific shipping.

Yet, this partnership is not a sudden geopolitical invention. It is the latest chapter in a relationship shaped by more than two millennia of maritime exchange. Long before the modern nation-state existed, merchant ships from the Indian subcontinent sailed across the Bay of Bengal carrying cotton textiles, spices, beads, precious stones and metalware to the Indonesian archipelago. In return, they brought back cloves, nutmeg, camphor and other valuable commodities that fuelled one of history's most lucrative trading networks. These voyages also carried ideas, religions, languages and artistic traditions, leaving an enduring cultural imprint across Southeast Asia. Even today, the influence of the Ramayana and Mahabharata remains deeply embedded in Indonesian art, theatre and architecture—a reminder that the sea has long connected these two nations long before it became a stage for modern geopolitics.

Part 2: Why the Strait of Malacca Matters as Much as the Strait of Hormuz

If the Strait of Hormuz is the world's most critical energy corridor, the Strait of Malacca is arguably the world's most important trade corridor. The distinction is significant. Hormuz primarily dominates global headlines because of its role in transporting crude oil from the Gulf, while Malacca carries a far more diversified cargo mix—containerised goods, crude oil, liquefied natural gas (LNG), iron ore, coal, automobiles, electronics, chemicals, food products and industrial raw materials. In many ways, Hormuz powers the world, but Malacca keeps global manufacturing and commerce moving.

Every year, more than 90,000 merchant vessels pass through the Strait of Malacca, linking the Indian Ocean with the South China Sea and the Pacific Ocean. Around one-quarter to one-third of global maritime trade uses this narrow passage, while nearly 80% of China's oil imports, a significant share of Japan's and South Korea's energy supplies, and a large volume of ASEAN's exports depend on it. For countries across East Asia, Malacca is not simply a shipping route—it is an economic lifeline. Any prolonged disruption would ripple through factories, ports, warehouses and retail markets across multiple continents.

Unlike Hormuz, where alternative pipelines can partially offset disruptions, Malacca offers very few practical substitutes. Ships can divert through Indonesia's Lombok Strait or Sunda Strait, but these routes are considerably longer, increasing sailing time, bunker fuel consumption, charter costs and insurance premiums. For container shipping, where schedules are tightly integrated with global supply chains, even a delay of two or three days can disrupt manufacturing cycles and inventory planning. This vulnerability is one of the reasons why the maritime industry closely monitors developments in the Indo-Pacific.

The strategic importance of Malacca has also shaped global geopolitics. Former Chinese President Hu Jintao famously referred to the country's dependence on this sea lane as the "Malacca Dilemma." Nearly all of China's imported oil from the Middle East and Africa must pass through this narrow corridor before reaching Chinese ports. This dependence has driven Beijing to invest in alternative trade routes, pipelines and port infrastructure under the Belt and Road Initiative (BRI), while simultaneously expanding its naval presence in the Indian Ocean. For India, these developments reinforce the importance of maintaining a stable, open and rules-based maritime order in the region.

This is where the partnership between India and Indonesia takes on greater significance. India sits at the western edge of the Indo-Pacific, while Indonesia stretches across one of the world's largest archipelagos, controlling access to several strategic waterways, including the Strait of Malacca, Sunda Strait and Lombok Strait. Together, they occupy positions that naturally complement each other in safeguarding international shipping and promoting maritime connectivity. Their cooperation is not aimed at controlling trade but at ensuring that one of the world's busiest sea lanes remains secure, efficient and open to all.

The strategic value of Sabang Port lies precisely in this geography. Located at the northern tip of Indonesia's Aceh Province, Sabang is among the closest deep-water ports to the western entrance of the Strait of Malacca. For decades, it remained underutilised despite its location. That perception began to change after India and Indonesia signed agreements to strengthen maritime cooperation and explore the development of Sabang's port infrastructure. While Sabang is often discussed from a defence perspective, its long-term commercial potential is equally compelling.

For the shipping industry, Sabang could evolve into a valuable support hub offering bunkering, ship repair, emergency maintenance, crew changes, maritime services and logistics support for vessels transiting one of the busiest sea lanes in the world. As shipping companies increasingly seek operational flexibility and alternative service locations, ports positioned near major chokepoints are becoming more attractive. Sabang's proximity to the Strait of Malacca gives it a strategic advantage that extends beyond military considerations.

India's Great Nicobar Transshipment Port Project complements this vision from the opposite side of the Andaman Sea. Designed to handle some of the world's largest container vessels, the project aims to reduce India's dependence on foreign transshipment hubs such as Singapore, Colombo and Port Klang, where a large share of Indian container cargo is currently transferred. If successfully integrated with broader regional shipping networks, Great Nicobar could enhance India's role in global maritime logistics while improving supply-chain resilience for exporters and importers.

Viewed together, Sabang and Great Nicobar are not competing ports—they are potentially complementary nodes in a larger Indo-Pacific logistics network. One sits at the entrance to the Strait of Malacca, while the other is being developed as a modern transshipment hub overlooking the same maritime corridor. Improved connectivity, coordinated maritime safety, digital shipping systems, search and rescue cooperation and commercial partnerships between these locations could create efficiencies that benefit shipping lines, cargo owners and regional economies alike.

Perhaps the most important lesson from recent disruptions in the Red Sea, Black Sea and Strait of Hormuz is that resilience has become as valuable as capacity. Ports are no longer judged solely by the number of containers they handle but by the role they play in keeping global trade moving during times of uncertainty. In that context, the emerging maritime partnership between India and Indonesia is about far more than bilateral relations—it is about strengthening one of the world's most vital trade corridors before the next global disruption occurs.

Part 3: From Strategic Geography to a Logistics Powerhouse

History has often shown that geography rewards nations that recognise its value before everyone else. Singapore transformed itself from a small island into the world's busiest transshipment hub not because it had vast natural resources, but because it capitalised on its location. The same principle now applies to the waters between Sabang and Great Nicobar. While these locations cannot replace established hubs overnight, they have the potential to complement the existing maritime ecosystem by offering additional capacity, operational flexibility and resilience at one of the world's busiest shipping gateways.

For India, the timing is significant. The country's merchandise exports are expanding, manufacturing is receiving fresh momentum through initiatives such as 'Make in India', and New Delhi aims to reduce logistics costs while strengthening its position in global supply chains. Yet, a large share of Indian container cargo is still transshipped through foreign ports before reaching international destinations. The development of the Great Nicobar International Transshipment Port is intended to change that by enabling more direct connectivity for mainline container vessels. If supported by efficient customs procedures, multimodal connectivity and competitive port services, the project could help India retain a greater share of maritime value addition within its own logistics ecosystem.

Indonesia, meanwhile, stands to gain by enhancing the commercial role of Sabang Port. Beyond serving as a strategic location near the western entrance of the Strait of Malacca, Sabang could evolve into a regional maritime services hub offering bunkering, ship repair, crew changes, emergency response, offshore logistics support and blue economy activities. As global shipping companies increasingly seek diversified service locations, ports that combine strategic geography with modern infrastructure are likely to attract greater commercial interest. Improved connectivity between Sabang and India's Andaman and Nicobar Islands could also encourage tourism, fisheries cooperation, disaster-response coordination and maritime research, broadening the partnership beyond cargo movement alone.

The significance of this corridor extends beyond the two countries. As manufacturers diversify production across India, Southeast Asia and the wider Indo-Pacific, supply chains are becoming more distributed and less dependent on a single country or route. This shift increases the importance of reliable maritime infrastructure capable of supporting uninterrupted trade. Investments around the Sabang–Great Nicobar axis should therefore be viewed not only as national infrastructure projects but as contributions to regional supply-chain resilience. A stronger maritime network in the eastern Indian Ocean can benefit exporters, shipping lines, insurers and logistics providers across Asia.

There are, however, challenges that cannot be overlooked. Building a successful maritime corridor requires more than deep-water ports. It demands efficient hinterland connectivity, digital port systems, competitive tariffs, skilled manpower, environmental safeguards and predictable regulatory frameworks. The Great Nicobar project has also generated debate regarding its environmental impact, particularly because the island is home to ecologically sensitive forests and unique biodiversity. Balancing economic development with environmental conservation will be essential if the project is to achieve long-term sustainability. Similarly, Sabang's commercial potential will depend on sustained investment, regional cooperation and the ability to attract regular shipping services.

Despite these challenges, the direction of travel is becoming increasingly clear. The maritime partnership between India and Indonesia is evolving from diplomatic symbolism into practical economic cooperation. Both countries have strengthened collaboration through the 2018 Shared Vision of India–Indonesia Maritime Cooperation in the Indo-Pacific, expanded naval and coast guard engagement, and continued dialogue on port development, maritime connectivity and the blue economy. These initiatives reflect a broader understanding that secure and efficient sea lanes are fundamental to economic growth in the Indo-Pacific.

Editorial Perspective

For years, discussions about the Indo-Pacific have been dominated by naval deployments, strategic rivalries and geopolitical competition. While these issues remain important, the next chapter is likely to be written by ports, logistics corridors and supply chains rather than by warships alone. Countries that build efficient maritime infrastructure, reduce logistics costs and strengthen regional connectivity will shape the future of global trade far more effectively than those relying solely on military influence.

The 710 kilometres between Sabang and Great Nicobar illustrate this shift. Rather than viewing these locations as isolated strategic outposts, they should be seen as complementary gateways at the entrance to one of the world's busiest sea lanes. If developed with a long-term commercial vision, supported by modern logistics infrastructure and integrated into regional shipping networks, they could emerge as an important pillar of Indo-Pacific maritime connectivity.

The Strait of Hormuz will continue to dominate headlines whenever energy markets are under pressure. Yet, the Strait of Malacca quietly carries the cargo that keeps factories running, store shelves stocked and global commerce moving. Its importance is measured not only in barrels of oil but in the uninterrupted flow of containerised trade that underpins the modern economy.

For the logistics industry, the message is straightforward: the future of maritime trade will not be determined solely by the world's largest ports, but by how effectively nations create resilient networks around its most critical sea lanes. The emerging partnership between Sabang and Great Nicobar is one such network in the making—one that deserves close attention from shipping companies, investors, policymakers and exporters alike.
