HORN OF AFRICA & RED SEA— Ports as Instruments of Geopolitical Power

 

HORN OF AFRICA & RED SEA-

Ports as Instruments of Geopolitical Power.

A port is often described as infrastructure.

But in the Horn of Africa and Red Sea, some ports are becoming something much more consequential:

instruments of economic, diplomatic and strategic power.

A modern port can determine:

• which countries have access to trade;
• which corridors become commercially viable;
• who controls logistics infrastructure;
• where foreign companies invest;
• where military forces can operate;
• which inland economies gain maritime access;
• and, increasingly, which governments gain diplomatic leverage.

The four cases of Berbera, Djibouti, Port Sudan and Assab demonstrate four different versions of this phenomenon.

1. What makes a port geopolitically important?

A port becomes strategically important when it sits at the intersection of several networks.

Maritime network

Where are the major shipping lanes?

Economic network

Which countries depend on the port?

Infrastructure network

Is it connected to roads, railways, pipelines and industrial zones?

Security network

Can naval or coast-guard forces operate from it?

Political network

Which governments, companies or foreign powers have interests there?

Resource network

Does the port handle oil, gas, minerals, livestock, food or other strategic commodities?

The most powerful ports combine several of these functions.

That is why port geopolitics is really corridor geopolitics.

2. Berbera — the port that challenges a regional monopoly

Berbera sits on the Gulf of Aden, close to the maritime route leading toward Bab el-Mandeb.

Its strategic importance increased substantially after DP World began operating and upgrading the port in 2017.

The port is now integrated with the Berbera Economic Zone and the road corridor toward Ethiopia. DP World describes the port and economic zone as an integrated maritime, logistics and industrial hub designed to serve Somaliland and the wider Horn, including Ethiopia. 

This changes the strategic equation.

Previously, Ethiopia's principal maritime gateway was overwhelmingly:

Ethiopia → Djibouti.

Berbera introduces another possibility:

Ethiopia → Berbera → Gulf of Aden → Global shipping.

3. Berbera is therefore about Ethiopia

The port's importance cannot be understood simply by looking at Somaliland.

The larger prize is the Ethiopian market.

Ethiopia is landlocked and has more than 130 million people.

The World Bank describes the Addis-Djibouti corridor as a vital trade route for Ethiopia, demonstrating how strategically important maritime access is to the country's economy. 

Berbera offers Ethiopia another potential gateway.

DP World and Ethiopia signed an MoU in 2021 to explore development of the Ethiopian side of the Berbera corridor, with DP World and partners envisaging substantial investment in supply-chain infrastructure. 

This means a port can change the bargaining relationship between:

landlocked Ethiopia

and

coastal gateways.

4. Berbera also demonstrates the political nature of ports

Berbera is not merely a commercial project.

It is located in Somaliland, which has operated as a de facto independent polity since 1991 but lacks broad international recognition as a sovereign state.

Consequently, investment in Berbera intersects with questions of:

• Somaliland's international status;
• Somalia's territorial claims;
• Ethiopia's maritime ambitions;
• UAE commercial interests;
• regional trade competition.

Academic research has specifically described Berbera as a case where infrastructure intersects with sovereignty, recognition, external investment and market access. 

This is an important lesson:

A port can become part of a sovereignty debate.

5. Djibouti — the port that became a national strategy

If Berbera represents an emerging alternative, Djibouti represents the established model.

Djibouti's geography places it beside the Bab el-Mandeb.

But its greatest commercial advantage comes from another fact:

Ethiopia is landlocked.

The World Bank reports that approximately 80% of merchandise handled through Djibouti's ports consists of onward transit and reexports to Ethiopia, generating significant port-related revenue. 

The IMF similarly describes Djibouti as the principal maritime gateway for Ethiopia and highlights the infrastructure investments—including the Addis-Djibouti railway—that have supported this role. 

Djibouti has effectively transformed geography into an economic model:

Strategic location

Port infrastructure

Ethiopian trade

Logistics services

Foreign investment

Economic growth

6. Then came military power

Djibouti's ports are not its only strategic asset.

Its territory hosts military facilities used by several foreign powers, including the United States, China, France, Japan and Italy.

That produces an unusual combination:

Port

Trade corridor

Military facilities

Bab el-Mandeb

Ethiopian market

Submarine cables

The World Bank explicitly identifies Djibouti's location as contributing to both its military and economic strategic importance. 

Few African countries possess such a concentration of strategic functions in such a small territory.

7. Djibouti demonstrates that ports create bargaining power

Djibouti's strategic position allows it to interact with multiple external powers simultaneously.

China has commercial and infrastructure interests.

The United States has military interests.

France has historical and defense interests.

Japan has maritime-security interests.

Italy and other European states have Red Sea interests.

Ethiopia has enormous commercial dependence.

This gives Djibouti an unusual diplomatic position.

It can effectively say:

"Access to this geography has value."

That is the essence of port geopolitics.

8. Port Sudan — when a port becomes a national lifeline

Port Sudan demonstrates another dimension of port power.

It is Sudan's principal maritime gateway on the Red Sea.

The World Bank identifies Port Sudan as the country's main seaport and describes its strategic position on the Red Sea, with facilities handling containers, bulk commodities, oil and other cargo. 

But Sudan's war has dramatically changed the port's significance.

When conflict severely disrupts Sudan's interior, the Red Sea coast becomes one of the few areas through which the country's international commerce, humanitarian assistance and diplomatic activity can operate.

The port therefore becomes more than:

a commercial facility.

It becomes:

a national lifeline.

9. Port Sudan demonstrates the security value of ports

Consider the geography.

Sudan's capital and much of its population are far inland.

The port connects the country to:

Saudi Arabia

Egypt

the wider Red Sea

Europe

Asia

If inland transportation collapses, the value of the port does not disappear.

Instead, its strategic importance can increase.

That is why ports often become crucial during wars.

Whoever can secure the port controls an important gateway for:

• imports;
• humanitarian supplies;
• fuel;
• military logistics;
• exports;
• diplomatic access.

10. The current Sudanese context

Sudan's conflict has also produced economic fragmentation.

Reuters reported on September 22, 2026 that Sudan's prolonged war has divided economic activity between areas controlled by the army and the Rapid Support Forces, severely weakening government revenue and normal commerce. 

In such circumstances, Port Sudan becomes strategically significant because access to the Red Sea remains essential to whatever national economic system can function.

This illustrates a broader principle:

During political crises, control of a major port can become almost equivalent to control of a country's external economic lifeline.

11. Assab — the military port

Assab demonstrates a different model.

Rather than primarily functioning as a commercial gateway, Assab became strategically important because of its military location.

It sits on Eritrea's Red Sea coast, relatively close to:

Yemen

Bab el-Mandeb

Saudi Arabia

and the maritime route toward Suez.

During the Yemen war, the UAE developed military infrastructure around Assab and used the location to support operations in Yemen.

SIPRI documented the presence of Emirati military aircraft, ground forces, a deep-water naval facility and training infrastructure at Assab.

The UAE subsequently reduced and partly dismantled the facility as its military involvement in Yemen changed. 

12. Assab demonstrates the military dimension of ports

A port provides something a military force operating far from home needs:

logistics.

Ships need:

• fuel
• ammunition
• maintenance
• supplies
• personnel
• repair facilities
• staging areas.

An airfield beside a port is even more valuable.

Together:

Port + airfield + road network

can create a forward operating hub.

Assab's experience therefore demonstrates how commercial-looking infrastructure can acquire military significance.

13. The four ports represent four types of power

Port	Principal strategic function	Wider geopolitical significance
Berbera	Trade + logistics	Ethiopia access, Somaliland politics, Gulf investment
Djibouti	Trade + military + logistics	Ethiopia, Bab el-Mandeb, foreign bases
Port Sudan	National trade lifeline	Sudan's war, Red Sea access, humanitarian logistics
Assab	Military/logistics	Yemen, Bab el-Mandeb, Eritrea's Red Sea position

The important point is that these functions can overlap.

A port that begins as commercial infrastructure can acquire:

diplomatic importance

then

security importance

then

military importance.

14. Ports are becoming "strategic nodes"

The modern port is increasingly part of a much larger network.

Think of:

Port

Road

Rail

Industrial zone

Warehouse

Customs

Digital infrastructure

Financial services

Military/security infrastructure

The port becomes the node connecting all of them.

That is why countries and corporations compete over ports rather than simply building isolated terminals.

15. The corridor is often more important than the port

This is perhaps the most important lesson.

A port without an efficient hinterland can have limited value.

Consider:

Berbera

Port
→ Berbera Corridor
→ Ethiopia

Djibouti

Port
→ railway/road
→ Addis Ababa

Port Sudan

Port
→ road/rail
→ Sudanese interior

The real geopolitical asset is therefore:

Port + corridor + market.

A port gives access to the sea.

A corridor gives access to the economy.

A market creates the commercial demand.

16. This is why Ethiopia is central

Ethiopia's landlocked status has transformed the Horn's port competition.

The country is large enough to create enormous demand for maritime services.

That creates competition among coastal gateways.

The basic strategic equation is:

Ethiopian trade

Demand for maritime access

Competition among ports

Foreign investment

Infrastructure development

Political leverage

This is why Ethiopia appears repeatedly in the geopolitics of:

Djibouti

Berbera

Somalia

Eritrea

and potentially Sudan.

17. Gulf investment changes the equation

The UAE has been particularly active in port development.

Its DP World operation at Berbera demonstrates how a commercial logistics company can become an important geopolitical actor through infrastructure.

DP World says its Berbera operation now includes container handling, general cargo, livestock exports, warehousing and customs facilities. 

This is strategically significant because logistics companies can influence:

where cargo moves

which corridors develop

which markets become connected

and which infrastructure receives investment.

18. Ports can create political influence without formal sovereignty

This is a subtle but important distinction.

A foreign government does not necessarily need to own territory to gain strategic influence.

Influence can come through:

operating a port

financing a port

building a road

managing a logistics zone

providing security

controlling a concession

or

connecting the port to an external network.

This is why port concessions deserve the same geopolitical attention as military agreements.

19. China's model is also important

China's involvement in African ports has frequently combined:

infrastructure finance

construction

logistics

trade

and, in selected locations, military access.

Djibouti is the clearest regional example because China's commercial infrastructure interests coexist with its overseas military support base.

The broader lesson is not that every Chinese port investment is military.

It is that:

Commercial infrastructure can create strategic relationships that last for decades.

20. The United States sees ports differently

For the United States, ports are important partly because they provide access for:

• naval operations
• intelligence
• counterterrorism
• logistics
• evacuation
• humanitarian operations.

Djibouti's Camp Lemonnier illustrates this model.

The American strategic interest is therefore often less about owning commercial port infrastructure and more about maintaining access and operational reach.

21. The UAE model is especially interesting

The UAE has pursued a more integrated model:

Port

logistics

economic zone

trade corridor

investment

security relationships.

Berbera is an example.

Assab was an example of the military side.

The combination gives the UAE influence over several layers of regional connectivity.

22. Ports can also reshape alliances

Suppose Country A controls an important port.

Country B invests in it.

Country C builds the road connecting it to an inland market.

Country D provides security.

Country E becomes the principal customer.

Suddenly, the port has created a network of relationships.

The infrastructure itself becomes a mechanism for diplomatic interaction.

This is why infrastructure can function as geopolitical statecraft.

23. But ports can also create dependency

There is another side.

If one external company or government controls a strategically important port under a long-term concession, the host state may become dependent on:

• external capital;
• external technology;
• external management;
• external shipping networks;
• external security.

That does not automatically mean the arrangement is harmful.

But it creates a strategic question:

Who ultimately captures the economic and political value generated by the port?

24. What African governments should examine

A port agreement should not be evaluated solely by:

"How many billions will be invested?"

It should also ask:

Revenue

How much does the state receive?

Employment

How many sustainable local jobs are created?

Ownership

What participation do African companies have?

Technology

What capabilities are transferred?

Infrastructure

Does the investment improve the surrounding corridor?

Industrialization

Does manufacturing develop around the port?

Security

Who controls security arrangements?

Duration

How long does the concession last?

Sovereignty

What strategic decisions remain under national control?

Regional integration

Does the port strengthen African trade?

These questions determine whether a port becomes an economic platform or primarily an external strategic asset located in Africa.

25. Port competition can benefit Africa

Competition among ports is not necessarily negative.

If Ethiopia can choose between:

Djibouti

and

Berbera

and potentially other corridors,

those ports have incentives to improve:

• prices
• efficiency
• customs procedures
• road connections
• reliability
• security.

Competition can therefore benefit users.

But it works best when African states have sufficient institutional capacity to negotiate and enforce fair commercial arrangements.

26. The Red Sea makes the stakes higher

These four ports are not isolated.

They sit around one of the world's most important maritime systems.

Assab

Djibouti

Bab el-Mandeb

Berbera / Gulf of Aden

Somalia

while farther north:

Port Sudan

Red Sea

Suez

This means port infrastructure in one country can affect the strategic calculations of several others.

27. Security can instantly change commercial value

The current Red Sea environment demonstrates this.

In September 2026, renewed fighting around Yemen and the Bab el-Mandeb has again increased pressure on maritime navigation. Italy's defense minister called for greater naval presence in the Red Sea, while international shipping routes face renewed security concerns. 

A port's value therefore depends partly on what happens beyond the port itself.

Geopolitics can change logistics overnight.

28. The maritime-security triangle

For African ports, three things increasingly need to work together:

Commercial capability

Can the port handle cargo efficiently?

Infrastructure connectivity

Can cargo move inland quickly?

Security capability

Can ships, cargo and infrastructure remain secure?

If any one fails, the other two suffer.

This is why port development should be treated as part of national security and economic strategy, not merely transport policy.

29. The future may be about port ecosystems

The most strategically valuable African port may not simply be the one with the biggest container terminal.

It may be the one surrounded by:

industrial parks

warehouses

railways

digital customs

financial services

ship repair

energy infrastructure

data centers

cold chains

manufacturing

maritime intelligence.

That turns a port into an economic ecosystem.

30. The African opportunity

Imagine a connected Horn:

Berbera

→ Ethiopia

→ manufacturing

→ exports

Djibouti

→ Ethiopia

→ East African trade

Port Sudan

→ Sudan

→ Egypt/Gulf markets

Assab/Massawa

→ Eritrea

→ Red Sea trade

Instead of four isolated ports competing for foreign investment, they could eventually form part of a broader regional maritime network.

That would require political cooperation that currently does not fully exist.

But the economic potential is substantial.

Central Lesson

Ports are no longer simply places where ships load and unload.

In the modern Horn of Africa, a strategic port can be:

an economic gateway

a trade corridor

a source of government revenue

a diplomatic bargaining chip

a military logistics hub

a food-security asset

an industrial platform

and a geopolitical instrument.

The four cases illustrate different models:

Berbera

Shows how a port can alter regional trade routes and become intertwined with sovereignty, Ethiopia and Gulf investment. 

Djibouti

Shows how a strategically located port can underpin an entire national economic model while attracting multiple foreign military powers. 

Port Sudan

Shows how a port can become a national lifeline when conflict disrupts a country's internal economy. 

Assab

Shows how a port can become a military projection platform because of its proximity to a maritime chokepoint.

And the broader lesson is:

Whoever controls access, infrastructure and corridors around a strategic port can influence far more than the movement of cargo.

They can influence trade routes, investment patterns, security relationships and diplomatic choices.

For Africa, the strategic objective should therefore go beyond attracting foreign port investment.

The deeper objective is to build African port ecosystems in which African governments, companies and workers capture a growing share of the value generated by the continent's extraordinary maritime geography.
