Geostrategy and how states turn geography into power

Geostrategy is the practical application of geography to national power. It explains how states turn their geographical position and natural resources into strategic objectives, backed by military strength and economic leverage.

The discipline examines how countries protect their interests and respond to rivals in specific regions. A state with deep-water ports and secure energy imports negotiates from a far stronger position than one that depends on a single supplier.

Take the Strait of Hormuz. Any state able to influence this narrow passage, through which a large share of the world’s oil travels, gains leverage over energy prices and trade flows well beyond its own borders. The Master in Geopolitics at Universidad Europea trains students to analyse exactly these dynamics through real-world cases and applied international scenarios.

What is the difference between geostrategy and geopolitics?

Geopolitics examines how geography shapes political power and international relations, while geostrategy focuses on the actions countries take to achieve their objectives within that geographical context.

The two concepts overlap, but they answer different questions.

• Geopolitics asks why a region matters strategically and what interests rival states hold there.
• Geostrategy examines how states turn those interests into action through military deployments, diplomatic agreements or economic measures.

China’s Belt and Road Initiative shows the split clearly. Its geopolitical logic is to extend China’s influence and secure trade routes. Its geostrategic dimension lies in the concrete decisions behind it, such as which ports to finance and which rail corridors to build.

International relations adds a wider lens, covering how states cooperate, negotiate and manage conflict through institutions, treaties and diplomacy. Read our article on geopolitics vs. international relations for an in-depth comparison of the two fields.

What tools and factors shape geostrategy?

Geostrategy combines a state’s geographical advantages with the hard and soft tools it uses to protect its interests and extend its influence. Five factors do most of the work.

• Geography and natural resources. Coastlines, ports and mountain passes shape trade and defence, as do energy reserves and critical minerals. The Strait of Malacca carries a large share of Asia’s seaborne energy imports, which makes it central to American and Chinese naval planning.
• Military power and alliances. Overseas bases, deterrence and defence pacts let states protect territory and project force. NATO’s Article 5 commits members to collective defence, which multiplies each member’s strategic weight.
• Economic power and trade. Sanctions, tariffs and energy exports turn commercial relationships into political leverage. Russia’s gas supplies to Europe before 2022 show how dependence becomes a strategic vulnerability.
• Diplomacy and partnerships. Treaties and multilateral bodies such as the EU or ASEAN let states build coalitions and pursue shared objectives without force.
• Technology and information. Semiconductor production, cyber capabilities and strategic communications shape national security as much as territory does. Taiwan’s dominance in advanced chip manufacturing explains why the island sits at the centre of US and Chinese competition.

These tools rarely work alone. When the state-owned shipping group COSCO acquired a majority stake in Greece’s Piraeus port, China gained a commercial gateway into European markets and a foothold in the eastern Mediterranean.

What are some real-world examples of geostrategy?

Competition over maritime routes, regional alliances and critical infrastructure illustrates how countries turn geographical and economic interests into strategic decisions.

The Strait of Hormuz

The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the wider Indian Ocean. Its importance to international energy transport makes it a strategic chokepoint.

Iran's position near the strait gives it geographical significance in regional security calculations. Other states have strong interests in keeping maritime traffic safe and maintaining access to energy supplies. Naval deployments, diplomatic negotiations and security partnerships all form part of the wider geostrategic picture.

The Indo-Pacific

The Indo-Pacific is central to competition between China and the United States because of its major shipping routes, economic importance and strategic military positions.

China has invested in infrastructure and strengthened its regional military capabilities, while the United States works with allies and partners to maintain its regional presence. Decisions about defence cooperation, trade and access to advanced technology reflect competing strategic priorities.

European energy security

Russia’s full-scale invasion of Ukraine in 2022 exposed the strategic risk of relying on a single energy supplier. Before the war, Russia provided roughly 40% of the EU’s natural gas imports, which gave Moscow leverage over European foreign policy.

European governments responded by turning to Norway, Qatar and the United States for supply, and by building liquefied natural gas terminals so they could receive cargoes from anywhere. Germany, which had no LNG import terminals before the war, commissioned its first floating terminal within months.

The episode shows how energy infrastructure and trade ties translate directly into political power. A pipeline or a port is a strategic asset as much as a commercial one.

What is geoeconomics and how does it relate to geostrategy?

Geoeconomics is the use of economic instruments to achieve geopolitical objectives, and it works as the economic arm of geostrategy. States use trade and investment to strengthen their international position without resorting to military force.

Sanctions show this clearly. When Western governments froze Russian central bank assets in 2022, they cut Moscow off from a large share of its foreign reserves. Export controls work in a similar way. China’s restrictions on gallium and germanium exports in 2023 targeted two metals that semiconductor and defence manufacturers rely on.

Investment pulls in the opposite direction, building ties instead of severing them. Financing foreign ports, railways and energy projects creates long-term commercial dependence that carries political weight.

Geoeconomics shows that the balance of power rests on more than military strength. Industrial capacity and control over critical supply chains decide who holds leverage in a crisis.

What careers involve geostrategy?

Geostrategy-related careers involve analysing international developments, assessing political risk and advising organisations on decisions affected by global power dynamics.

Potential career paths include:

• Geopolitical risk analyst, assessing how conflicts, elections and policy changes affect organisations and investments.
• Intelligence analyst, evaluating information about international security and potential threats.
• International affairs adviser, supporting foreign policy, diplomatic engagement or international cooperation.
• Strategic business consultant, helping companies evaluate international markets, political risks and expansion opportunities.
• Policy researcher, examining security, trade and foreign affairs for research institutes, think tanks or public bodies.

Geostrategy turns geography, resources and economic leverage into decisions that move markets and shape alliances, which is why analysts who understand it are in demand across international careers. If diplomacy and international organisations appeal to you, the Master in International Relations at Universidad Europea is taught in English and includes work placements at embassies, NGOs and international organisations.
