Ethiopia

Ethiopia's Grand Ethiopian Renaissance Dam (GERD) has created a major geopolitical standoff; Egypt regards Nile flow as an existential resource and views the dam as a threat to its water security, making this one of Africa's most consequential bilateral disputes.

After a devastating border war (1998-2000) and nearly 20 years of frozen hostility, the 2018 peace deal won Abiy Ahmed the Nobel Prize—but Eritrean forces subsequently fought alongside Ethiopian federal troops in the Tigray war, deepening the relationship's contradictions.

Ethiopia contributes troops to the AMISOM/ATMIS peacekeeping mission and is a regional security anchor, but its own internal instability limits its capacity and its interventions have sometimes generated resentment within Somalia.

Ethiopia hosts millions of Sudanese refugees while itself producing refugees during the Tigray war; the GERD dam dispute intersects with Sudanese water interests; political instability in Khartoum adds additional unpredictability to the relationship.
