Strategic Rivers, Illicit Trafficking and Global Competition

How the Paraguay–Paraná, Mekong, and Congo Shape the New Geopolitics of Routes

Key takeaways 

• River systems are not only trade routes but also pathways through which criminal networks and major global powers exert territorial control.

• Strategic waterways like the Paraguay–Paraná, Mekong, and Congo have become sites for drug trafficking, resource smuggling, and intense competition between Washington and Beijing for strategic resources and geopolitical power.

• To limit the risks, companies should monitor who controls the river transit routes and mitigate the logistical bottlenecks that could arise from political instability and variations in water levels.

Rivers as corridors of power

The world’s major rivers have, since antiquity, been vital arteries for the development of civilisations and continue to play this role today, albeit with a logistical duality. Emblematic examples include the Paraguay–Paraná, the Mekong, and the Congo. These waterways illustrate a global transformation in which river infrastructure is no longer merely an economic space sustaining the supply chains of global trade, but also a channel exploited by criminal networks to advance their interests and by major powers to project their influence and exercise control.

The Paraguay–Paraná Waterway amid global exports, the PCC, and American control

The Paraguay–Paraná Waterway, stretching approximately 3,400 km through Brazil, Bolivia, Paraguay, and Argentina, is considered one of Latin America’s principal trade corridors. It connects production, transport, and logistics infrastructure, providing access to Atlantic Ocean ports and international markets. Based on an integrated regional system rather than a single country, the river supports the transit of vast quantities of agribusiness products—such as soya, wheat, and oilseeds—as well as fertilisers, fuel, and machinery for export.

However, the substantial economic flows along the Paraguay–Paraná create significant monitoring challenges, increasing vulnerability to criminal activity. The waterway does not involve a single form of smuggling but a wide range of illicit trade. It is used by cigarette and alcohol traffickers relying on clandestine ports, as well as family clans controlling tobacco and consumer electronics markets, combining these shipments with cannabis and cocaine consignments. Among the main criminal organisations operating along the route is the Primeiro Comando da Capital (PCC), which exploits Paraguay’s barge fleet—the third largest in the world—to conceal tonnes of cocaine inside legitimate container ships carrying agricultural products. Departing from the seaports of Rosario, Buenos Aires, and Montevideo, these vessels subsequently reach Europe.

Beyond licit and illicit trade, the Paraguay–Paraná has become a focal point of strategic interest for Washington and Beijing. The signing of the Status of Forces Agreement (SOFA) with Paraguay allows the United States to consolidate its presence in the basin by deploying military and intelligence personnel to counter narcotics exports and PCC activities. This presence also reflects the traditional logic of the “Monroe Doctrine”, under which Latin America is viewed as the United States’ traditional “backyard”, aiming to limit Chinese influence over strategic infrastructure and terminals linked to the basin, such as the Port of Paranaguá.

The Mekong River: a narcotics and cyber-scam hub in the grip of Chinese geopolitics

With a course of approximately 5,000 km, the Mekong flows through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam, supporting around 50 million people and representing the essence of South-East Asia. Winding across highly diverse countries, its course is characterised by political instability, difficult-to-control borders, and illicit economies, especially in the Golden Triangle, where Thailand, Myanmar, and Laos converge and illegal trafficking routes towards regional markets originate.

The Golden Triangle is known as one of the world’s largest drug trafficking corridors. Criminal networks, including the Shan State militias in Myanmar, exploit remote areas and porous borders to establish production centres for heroin, opium, and synthetic drugs such as methamphetamines. These substances are transported along the Mekong by fast boats and fishing vessels to neighbouring countries before reaching New Zealand, Australia, and Japan. Beyond narcotics, the region has experienced a major proliferation of illegal cyber-scam centres managed by Chinese criminal networks, which have developed sophisticated technology-based fraud schemes. In response, China has progressively expanded its law enforcement presence along the Mekong through military patrols.

While China combats criminal activity along the Mekong, it also recognises the river’s significant energy, economic, and strategic potential as a geopolitical hotspot. Beijing exploits the waterway for domestic hydroelectric power generation through infrastructure projects such as the Xiaowan and Nuozhadu dams. The Mekong is also viewed as a crucial logistical channel towards ASEAN markets and a partial alternative to the “Malacca Dilemma”, driven by China’s fear of a naval blockade by the American navy, which maintains a strong surveillance and power projection presence in the Indo-Pacific region.

Control over critical minerals and militia smuggling in the Congo Basin

Like the Mekong, the Congo River also flows for almost 5,000 km and represents one of Central Africa’s most important natural waterways. With a basin covering most of the Democratic Republic of Congo (DRC), it extends across a region rich in strategic mineral resources such as cobalt, copper, lithium, and other high-value industrial inputs for the advanced electronics sector. Unlike the Paraguay–Paraná Waterway and the Mekong River, the basin’s vulnerability does not depend on the volume of commercial traffic, but rather on weak local institutions, chronic infrastructure shortages, and persistent insecurity, especially in the eastern provinces.

This instability has allowed criminal organisations and rebel factions to continue illegal extraction, smuggling, and violent competition over resources. Although the area is not controlled by a single drug cartel, it hosts a fragmented network of armed actors, including the Congo River Alliance (AFC), a political and military coalition led by the M23 paramilitary group. The AFC exploits instability in eastern DRC to fuel cross-border smuggling of valuable minerals, particularly with Rwanda.

Growing global demand for strategic minerals has turned the DRC into a field of intense international competition, with the United States financing a US$100 million programme to train a paramilitary mining guard aimed at securing extraction sites and mineral supply chains. Washington’s goal is to establish a geopolitical presence in the country beyond the Lobito Corridor, seeking to counter the near-monopoly China has held for years over Congolese mining concessions.

What risks threaten international businesses?

In this context, companies should map their suppliers not only by state borders, but also by monitoring who controls transit waterways militarily. Businesses exporting agricultural products or raw materials from these areas face the risk that criminal organisations may use their containers to conceal drugs or conduct illicit activities. When supply chain contamination occurs, consequences may include cargo seizures, vessel blockages, and criminal investigations into the company. Furthermore, where waterways are influenced by dams and containment infrastructure, sudden drops in river levels may occur, blocking commercial transport for entire weeks.
