The Strait of Malacca: Where World War III Starts?

In the coming decades, the world’s most significant geopolitical flashpoint may not be Ukraine, Kashmir, or the 38th Parallel. Instead, a narrow stretch of water—laconic, shallow, and light blue—has the potential to become the most consequential corner of the globe. The Strait of Malacca is where mounting tensions between India and China could fully ignite.

Strait of Malacca: Why It Matters

The strait, nestled between the Malay Peninsula and the Indonesian island of Sumatra, functions as the primary shipping channel between the Pacific and Indian oceans. In connecting all of Asia’s massive economies together, the strait serves as the world’s second busiest waterway (behind the English Channel). Each year, more than 83,000 vessels traverse the narrow route. And every day, roughly 16 million barrels of oil flow through the strait. Accordingly, the Strait of Malacca is a crucial chokepoint, dictating control of the entire Asian sphere.

Asia’s two biggest economies, India and China, are mortal adversaries. Centuries of border disputes and economic nationalism have tainted Sino-Indian relations. Just last year, the two countries engaged in a series of border disputes over Ladakh. In one such incident, indicative of the extreme vitriol between the countries, Indian and Chinese troops fought to the death, in the dark, for six hours—using stones, rods, and clubs embedded with nails. Perhaps the only thing that has so far prevented a full-scale conflict between the world’s two most populous nations is the impenetrable Himalayan mountain range, serving as a natural buffer.

Globally Rivalries

Now however, as India and China compete to become global players, both nations are setting their sights seaward, where no natural buffer exists to prevent open conflict. The Strait of Malacca is where the two nations will collide.

Historically, India has enjoyed a natural, strategic advantage over China in the Strait of Malacca. With naval bases nearby in the Andaman and Nicobar Islands, India has had the ability to pinch off Chinese use of the strait. China, who imports most of its massive influx of oil through the strait, has a strong incentive to wrest control of the strait from India. Ongoing Chinese naval production indeed suggests a growing ambition to dominate nearby waterways.

China is currently engaged in what may be the world’s largest ever shipbuilding spree. Chinese President Xi Jinping is racing to rival the US Navy. And recently, the People’s Liberation Army Navy (PLAN) surpassed the Americans, at least with respect to quantity; China now boasts the world’s largest naval force. Today, the PLAN has 360 ships—a 300% increase over the last two decades. With this massive, newly built naval capacity, China can project power throughout the Asian region—to the detriment of India.

Feeling the pressure of Chinese naval expansion, India is fighting to reciprocate. Although unlikely to match China, India has built one of the world’s largest and most powerful navies. Currently, the Indian Navy has 43 vessels under construction—all part of a decade-long plan to create a 200 ship Navy. India’s fervent ship building indicates an ambition to project power far from the shores of the subcontinent. India’s outward ambitions will directly conflict with China’s outward ambitions.

The place where these incompatible ambitions, and shining-new navies, will first collide: The Strait of Malacca.

Sino-Indian hostilities over the strait would prompt an international response. In all likelihood, the conflict would become a cosmopolitan affair. America, eager to contain China, would support Indian efforts to do the same.

Russia, eager to counter American global influence—and closer with Xi than ever—would support China.

Indeed, the narrow waterway separating the Pacific Ocean from the Indian Ocean has the potential to spark a global conflagration featuring the world’s most powerful nations.

Watch closely as the Strait of Malacca becomes the world’s most important geopolitical hotspot.

    India and China are both allies of Russia and in light of present conditions are beginning to approach rapprochment with bith Russia and themselves .

    Allies must share national interests. Where is the shared interest between Russia and China, aside from the failure of communism in the 20th century? How about either Russia and India or China and India? Each country is separated from the others by large mountain ranges. Similar high potential barriers would seem to separate these countries culturally. Some rapprochement is possible, but the age old lines of cleavage will remain.

    How vulnerable are modern ships to smart bombs? Without clear air superiority, very vulnerable. How vulnerable are the Straits of Malacca to air interdiction? How long can a naval barricade of the Straits persist in today’s world?

    The Straits are the shortest route for much necessary Chinese trade, but not the only route. A powerful navy might bar the Straits, but could it bar routes south of Indonesia or south of Australia? That much trade passes by the Straits doesn’t mean that there aren’t good alternatives.

    It’s interesting to think about the huge amount of shipping now using the Straits, but also interesting to consider alternatives.

    The flaw in this analysis is that it assumes the entirety of international relations and conflicts takes place in a vacuum between two nations. If the entirety of the real world is included one would have to factor in the responses of all the other nations who rely on the straits for commerce. Shutting down the straits brings all of them (Malaysia, Indonesia, Japan, Korea, Taiwan, Philippines, Vietnam, Thailand) into play.

    Given the modern day structure of the global shipping industry where ships are owned by companies in one country, financed by banks in multiple countries, registered in another country, insured by investors in a third and crewed by multiple nations, good luck trying to selectively identify which ships and cargoes are bound to/China (or India).

    Now it’s a different story if you’re talking about keeping the PLAN out of the Indian Ocean basin
