Egypt and Ethiopia expel each other's diplomats as Nile tensions rise
On 1 October Ethiopia declared an Egyptian diplomat persona non grata and gave him 48 hours to leave. Egypt retaliated on 2 October by expelling an Ethiopian counsellor within the same deadline. Neither side gave a reason.
According to The National, Ethiopia's Foreign Ministry gave Ahmed Moharam Ahmed Soliman, a senior diplomat at the Egyptian embassy, 48 hours to leave the country. Ethiopia Observer reported that a senior Egyptian official called the decision unjustified. The official said Egypt firmly rejects interference in the internal affairs of other countries. The moves came on the same day, 1 October, that Ethiopia closed its embassy in Asmara and expelled 10 Eritrean diplomats.
Addis Ababa accuses Egypt, Eritrea and Sudan of backing the opposition alliance led by the Tigray People's Liberation Front (TPLF) in the war in the north. According to The National, Cairo called these accusations unfortunate and unjustified. The underlying tension between the two countries is the Grand Ethiopian Renaissance Dam (GERD), which Ethiopia built on the Blue Nile. The Blue Nile supplies more than 80% of Egypt's water.
Egypt has recently expanded its military presence in Sudan, Eritrea, Djibouti and Somalia. According to The National, the Egyptian contingent in Somalia could reportedly grow from 15,000 to 30,000 troops. A base near Mogadishu is also reportedly being expanded for helicopter and light aircraft operations. These troop numbers are not based on an official statement and could not be independently verified.
Talay assessment
Bottom line
Within 2 days, the tit-for-tat expulsions turned Ethiopia's civil war into simultaneous diplomatic crises with Eritrea and Egypt. For Egypt, the issue is Nile water and its military presence along the Red Sea. For Ethiopia, it is the alleged foreign support for the TPLF. The most likely path is that relations freeze at a low level without being severed.
Likely effects
- Red Sea and Horn of Africa securityNegative1–6 months
The possibility of Egypt raising its Somalia contingent to 30,000 widens the scope for indirect military friction with Ethiopia.
- Nile water bargainingNegative6 months+
The expulsions lower the chance of GERD talks resuming in the near term with Egypt, which relies on the Blue Nile for more than 80% of its water.
- Link to the Sudan frontNegative1–6 months
By accusing Sudan, alongside Egypt and Eritrea, of backing the TPLF, Ethiopia raises the risk of tying the Sudanese and Ethiopian wars into a single regional theatre.
