In the contemporary international system, competition among great powers no longer manifests itself solely through traditional wars or direct military confrontations. Instead, it increasingly unfolds through indirect instruments of economic, financial, and logistical pressure. Among these tools, control of the sea and of global commercial mobility represents one of the most powerful—and at the same time most delicate—levers of influence. The United States, heir to a long Anglo-Saxon tradition of maritime supremacy, continues to regard dominance over the oceans as a fundamental pillar of its global hegemony.
In recent years, however, the sea has ceased to be merely the guarantor of globalization and is increasingly becoming a space where trade flows can be selectively disrupted. The use of naval power to exert pressure on international commerce through sanctions, inspections, interdictions, and maritime deterrence is a strategy that generates deep concern, especially in China, now the world’s largest trading power. Beijing, whose prosperity depends vitally on the freedom of maritime trade, views this evolution as a structural threat to its economic model.
At the same time, cases such as Venezuela demonstrate how the maritime domain can be used to economically strangle a country without resorting to open armed conflict. This article analyzes how the United States is progressively integrating naval power into its global pressure strategy, the implications for world trade, and why this dynamic represents one of the most feared scenarios for China.
Naval Power as an Economic and Political Instrument
Historically, control of the sea has never been solely a military issue. Maritime powers have always used their fleets to protect their own trade while simultaneously obstructing that of their rivals. In the modern era, this logic has adapted to a globalized world in which commerce is deeply interconnected and value chains stretch across oceans and continents.
The United States possesses the most powerful and globally deployed navy in the world. This presence allows Washington not only to guarantee the security of maritime routes, but also to monitor, regulate, and, in selective cases, hinder specific commercial flows. Unlike the classic naval blockades of the past, today’s practices operate within a more complex framework that includes economic sanctions, restrictions on maritime insurance, pressure on ports, financial constraints, and naval inspections justified by security concerns or regulatory compliance.
The result is a form of maritime economic pressure that is not always openly declared, yet can have profound effects on targeted economies. This instrument is particularly effective because it exploits the structural dependence of global trade on the sea—an element that no major economy can afford to ignore.
World Trade as a Strategic Vulnerability
More than 80 percent of global trade by volume is transported by sea. Oil, liquefied natural gas, raw materials, agricultural products, industrial components, and consumer goods all depend on stable and predictable maritime routes. This dependence turns the sea into a critical infrastructure of the global economic system.
Those who are able to influence access to this infrastructure acquire enormous political and economic leverage. It is not necessary to physically stop every ship; often it is sufficient to increase perceived risk, insurance costs, or regulatory uncertainty to make trade economically unviable. In this sense, naval power becomes a tool for the selective regulation of global commerce.
The United States, thanks to its navy and its influence over international financial and insurance institutions, is uniquely positioned to exercise this type of pressure. It is precisely this combination of military power, financial control, and logistical centrality that makes the American maritime strategy so feared by its rivals.
Why This Strategy Is China’s Greatest Fear
China is today the world’s largest trading nation. Its economic model is based on exports, the import of raw materials, and deep integration into global value chains. All of this depends critically on the sea. Chinese factories produce for markets thousands of kilometers away, while the energy resources that fuel the Chinese economy arrive primarily via maritime routes.
Beijing is fully aware that, in the event of a systemic crisis, its greatest vulnerability is not military but logistical and economic. Even a partial obstruction of maritime routes, an increase in transport costs, or heightened uncertainty at major global chokepoints could have devastating effects on the Chinese economy. For this reason, the prospect of an increasingly assertive use of US naval power to shape global trade is considered an extremely dangerous strategic scenario.
China has responded to this vulnerability by seeking to diversify transport routes, investing in land-based infrastructure, alternative energy corridors, and strategic ports through the Belt and Road Initiative. Nevertheless, these alternatives cannot fully replace maritime transport, especially in the short and medium term. The sea remains the critical pressure point of China’s commercial system.
The Venezuela Case: Maritime Pressure and Economic Strangulation
Venezuela represents a clear example of how the maritime domain can be used to exert profound economic pressure on a country without direct military intervention. The Venezuelan economy depends heavily on oil exports, which occur almost exclusively by sea. Limiting the country’s ability to export hydrocarbons means striking at the very core of its economy.
In recent years, US sanctions against Venezuela have gone far beyond the financial sphere. Restrictions on shipping companies, pressure on maritime insurers, inspections of vessels, and the deterrent effect of naval presence have made it increasingly difficult for Caracas to freely trade its oil. Even in the absence of a formally declared naval blockade, the cumulative effect has been a severe limitation of the country’s commercial capacity.
This strategy demonstrates how the sea can be transformed into an instrument of gradual economic strangulation. Rather than stopping all ships outright, trade is made so costly, risky, and complex that volumes are drastically reduced. It is a form of maritime economic warfare that operates over time, steadily eroding the resilience of an already fragile economy.
From Globalization to the Selective Control of Trade Flows
For decades, US naval power was perceived as the guarantor of globalization. Sea lanes were secure, trade flowed, and economies expanded. Today, however, this paradigm is undergoing a profound transformation. The sea is no longer merely a neutral space of exchange, but increasingly a domain in which flows can be selectively slowed, restricted, or conditioned based on geopolitical considerations.
This evolution has far-reaching consequences for the global economy. When trade becomes a tool of political pressure, confidence in the international system weakens. Companies begin to rethink supply chains, states seek greater self-sufficiency, and the risk of economic fragmentation increases.
For China, this scenario is particularly alarming. A world in which maritime trade is increasingly politicized is a world in which its dominant position as a global exporter can be challenged not on the basis of competitiveness, but on access to markets and transport routes.
Global Geopolitical Implications
The use of naval power to influence trade does not affect only directly targeted countries such as Venezuela; it has systemic consequences. Other actors closely observe these dynamics and draw strategic conclusions. Russia, Iran, and China interpret these practices as proof that the global economic order can be weaponized.
This perception strengthens the push toward alternative systems, parallel trade routes, and non-Western financial mechanisms. However, the transition to a truly multipolar economic system is complex and slow. In the meantime, the sea remains the primary and largely invisible battlefield of global competition.
From Washington’s perspective, these strategies are viewed as legitimate tools to defend national interests and uphold the international system it helped build. The core tension lies precisely in this divergence of perceptions: what the United States frames as stabilization is experienced by others as coercion.
Future Scenarios and Risks for the Global Economy
If the trend toward the selective use of naval power continues to intensify, the main risk will be a gradual militarization of global trade. Not in the form of open naval warfare, but through a persistent climate of uncertainty in which any maritime route can become a point of political pressure.
In such a scenario, trade costs would rise, global growth would slow, and inequalities between countries with secure maritime access and those exposed to disruption would widen. China, despite its efforts to adapt, would remain structurally vulnerable, while smaller economies could be severely squeezed.
The sea, once a symbol of connection, thus risks becoming an instrument of division. This transformation marks a new phase of global competition, in which hegemony is exercised not only through production or technology, but through control over the vital flows of the world economy.
Conclusion
The use of naval power as a means to obstruct or condition global trade represents one of the most significant developments in contemporary geopolitics. The United States, drawing on its maritime supremacy, is increasingly integrating the sea into its global pressure strategy. This dynamic is particularly feared by China, whose economic power depends critically on the freedom of maritime trade.
The Venezuelan case illustrates how this strategy can be applied in practice to economically strangle a country without resorting to direct armed conflict. The implications extend far beyond any single case, touching on the future of globalization, the stability of the world economy, and the balance of power among major states.
In an increasingly fragmented world, the sea has returned to being the silent heart of global competition. Understanding this reality is essential to grasp not only US strategy, but also the fears, reactions, and calculations of those who, like China, know that their economic destiny still inevitably passes through the oceans.
