The US wants to revive talks on Ethiopia's Nile dam, but another strategic contest between Addis Ababa and Cairo has emerged in the Red Sea, which could complicate reconciliation efforts

For Addis Ababa, using Djibouti's port for trade is not enough; it wants its own sovereign access to international waters. However, this first needs the consent of suspicious neighbours.

Cairo hopes that by helping the Americans establish relations with Egyptian allies in the region, it will be better placed to deal with the threats posed by Addis Ababa
