Sea Access or War? Ethiopia's Red Sea Ambition Reignites the Horn

On 5th October, Abiy Ahmed was sworn in for another five-year term as Ethiopia's prime minister and used the moment to restate his most dangerous ambition. He stated: "Based on the principle of give and take, we will work diligently to ensure that Ethiopia has an outlet to the sea".¹ Four days earlier, Ethiopia had declared ten Eritrean diplomats persona non grata and given them forty-eight hours to leave. Eritrea responded by severing all diplomatic ties.²

Ethiopia lost its coastline in 1993, when Eritrea became independent.¹ Now, with fighting renewed in Tigray and Eritrean troops reported on Ethiopian soil, the question of sea access has become a question of war. So is Ethiopia pressing a fair economic case, or building a pretext to start a conflict?

Is Ethiopia's Grievance Real?

Ethiopia is the world's largest landlocked country by population.³ Almost all of its trade goes through one neighbour: Djibouti's ports carry 95% of Ethiopia's imports and exports by volume, and Ethiopia pays at least $400m a year in port fees alone, before the wider logistics bill is counted.⁴ TradeMark Africa estimates that logistics make up 27% of the final cost of Ethiopian firms' products, and that moving freight costs about 60% more than it does in Ethiopia's coastal neighbours.⁵ A country this large, trading through a single foreign corridor, pays whatever that corridor charges, which keeps it in an economic chokehold.

Yet the dependence runs both ways. According to the International Monetary Fund (IMF), Ethiopian trade accounts for about 95% of the business at Djibouti's ports.⁵ This matters because Djibouti needs Ethiopia's cargo as much as Ethiopia needs Djibouti's coast, which gives Addis Ababa real bargaining power in its dealings with Djibouti. However, the law also limits the extent of Ethiopia's claim. The UN Convention on the Law of the Sea gives landlocked states "the right of access to and from the sea", but the terms must be agreed with transit states, which maintain "full sovereignty over their territory".⁶ Even Ethiopia's own Institute of Foreign Affairs, a government body, accepts that the treaty does not grant Ethiopia "a right to a particular port".⁷ In essence, Ethiopia has a right to reach the sea through other countries' ports, on terms they agree to, but no right to a sovereign stretch of coast of its own.

Is Sea Access Becoming a Pretext for War?

Ethiopia's position has long pointed two ways. Abiy has repeatedly promised that he will not go to war for a port, and in March he said that "Ethiopia will not fire a single bullet at Eritrea, Somalia, Djibouti or Kenya".⁸ Yet officials have also insisted, according to the International Crisis Group, that wider port access is not enough and that Ethiopia needs "a sovereign seaboard with a naval base".³ What is new is the threat. On 19th October, Abiy told state media that Eritrea would face "extremely severe consequences" if it kept trying to destabilise Ethiopia.⁹

Eritrea reads this as a plan for conquest. In a note to the UN Security Council (UNSC), its government quoted General Abebaw Tadesse, deputy chief of staff of the Ethiopian army, as saying on 27th September: "Mekelle is a mere stop-over, our ultimate destination is Assab".¹⁰ Mekelle is the capital of Tigray, and Assab is Eritrea's southern port. Although the quotation comes from Asmara, a party to the conflict, and cannot be independently verified, it shows how far tension over the coastline has grown between the two nations.

But the case against Ethiopia is not the whole story. The conflict monitor ACLED reported that Eritrean forces crossed the border near Zalambessa in the early days of October. Ethiopia then told the UNSC that Eritrean troops had pushed as far as 60km into Tigray, and invoked its right to self-defence under Article 51 of the UN Charter.¹¹ The fighting began not with a march on Assab, but with a Tigrayan offensive on 23rd September, a day after Ethiopian drone strikes on southern Tigray, and Ethiopian officials say they have no plans to take the war into Eritrea itself.³

Who Pays If the Horn Goes to War?

Ethiopia would inevitably suffer first. It is in the middle of a $3.4bn IMF programme that has already paid out about $2.6bn, and the Fund anticipates growth of 8.2% in 2026/27.¹² A war with Eritrea would put that growth at serious risk. The last conflict is a warning: researchers at Ghent University put the civilian death toll of the 2020 to 2022 war at around half a million, counting those killed by the fighting, by hunger and by the breakdown of healthcare.¹³

The region would suffer as well. At New Alamein on 4th October, Egypt, Eritrea, Sudan and Somalia insisted that only the countries on its shores should govern the Red Sea.¹ With the Iran war choking shipping through the Strait of Hormuz, the Red Sea route matters more than ever.¹⁴ Washington has noticed the danger in the area: on 14th October, Marco Rubio told Abiy that "all countries in the Horn of Africa must respect the sovereignty and territorial integrity of their neighbors".¹³

The Fair Verdict

Ethiopia's grievance over its lack of a coastline is fair, given the economic cost of relying on a single foreign port. No country of its size should depend on one corridor to trade, and the cost shows up in every price its businesses pay. The remedy Abiy now describes is not fair: a sovereign coastline with a naval base could only come from a neighbour's territory, most plausibly Eritrea's or Somalia's, and none will hand it over without a fight.

Peaceful alternatives do exist. In the Ankara Declaration of December 2024, Ethiopia and Somalia pledged to agree commercial terms that would give Ethiopia access to the sea.¹⁵ Nearly two years on, no deal has been signed,¹⁶ but the door is still open: Somalia's president has said he has no objection to Ethiopian trade passing through Somali ports, provided Mogadishu agrees the terms.¹⁴ The UAE, the UK and the EU have also put money into the trade route through Somaliland's port of Berbera.⁴ Djibouti, which depends on Ethiopian cargo, has every reason to offer better terms, although nothing in international law obliges it to. Each of these options would cut costs at a fraction of the price of war.

Ethiopia deserves sea access, but its willingness to pursue it through conflict needs to be questioned and weighed against the peaceful alternatives. The burden is on Addis Ababa to drop the language of sovereignty, and on Asmara to keep its troops on its own side of the border to stop tension in the region growing further.
