Cairo assembles Eritrea, Somalia and Sudan as the Nile quarrel turns into a Red Sea quarrel

Around 1–2 October Ethiopia expelled an Egyptian diplomat without explanation and Cairo responded in kind, The National reported, in a rupture Addis Ababa frames around its accusation that Egypt is supporting rebels attacking federal forces — a conflict that has also broken Ethiopia’s relations with Eritrea. On Sunday 4 October, President Abdel Fattah El-Sisi hosted Eritrea’s Isaias Afwerki, Somalia’s Hassan Sheikh Mohamud and Sudan’s Gen. Abdel Fattah Al-Burhan at New Alamein, the first time the four leaders have met together. The Egyptian presidency described the purpose as co-ordination and consultation “on regional issues of interest”; The National, citing unnamed sources, reported the meeting would announce measures to consolidate the alliance including wider military co-operation — an anonymous claim, not an announced outcome. Egypt and Sudan warned against “unilateral measures” that harm downstream states.

The same day, Prime Minister Mostafa Madbouly told CNN Business Arabic the Nile is a matter of “national security and existential importance” for a country drawing roughly 95 per cent of its water from the river, said Egypt remains committed to a diplomatic solution, and identified the real exposure: “The major challenge arises during multi-year droughts: how the dam is refilled could significantly impact Egypt’s water resources.” On 6 October El-Sisi hardened the position, calling Egypt’s share a “historical and legal” right that cannot be negotiated and saying Egypt “will not tolerate any action that touches its water security.” Ethiopia’s foreign ministry answered on the maritime axis, saying any serious discussion of regional security “must account for Ethiopia’s legitimate interests and its enduring connection to the Red Sea.” In Seoul on 8 October, El-Sisi told a joint press conference with President Lee Jae Myung that responsibility for Red Sea security and governance rests exclusively with its littoral states.

Washington’s intervention landed on a different axis again. The State Department said increasing cross-border tensions between Ethiopia and Eritrea “have the potential to affect the entire region” and urged both “to respect the sovereignty and territorial integrity of their neighbors, exercise maximum restraint and return to dialogue and cooperation.” The statement names Ethiopia and Eritrea. It does not name Egypt — which is, for Cairo, the preferred outcome: the summit’s diplomatic cost is carried by the parties already fighting, while Egypt appears as convener rather than belligerent. The National characterised El-Sisi’s 6 October remarks as “the latest sabre-rattling in Cairo’s water dispute with Ethiopia.” That is the outlet’s judgement rather than a reported fact, and it is worth separating from the quoted language, which was legal and defensive in form even where maximal in content.

Assessment: Watch the conversion, not the rhetoric. Cairo has spent a decade losing the GERD argument on hydrology and treaty law; recast as Red Sea littoral sovereignty, the same dispute recruits audiences — Gulf states, shipping insurers, European navies — that never cared about refill schedules. Ethiopia understood this immediately, which is why its reply was about access to the sea rather than about water. Two things to distrust: a summit billed as a first with no published mechanism, secretariat or follow-up date is still a photograph, and the military co-operation attached to it rests on unnamed sources in a single outlet. Note also that this coalition is built from three states with severe internal fragility. Egypt is the only member able to underwrite anything, and its canal revenue is halved.
