This month, three high-level visits within the space of six days showed how the rivalry between Morocco and Algeria is increasingly shaping the policies of European governments in the Maghreb.

On July 15 and 16, French Prime Minister Sebastien Lecornu led a large ministerial delegation to Morocco, consolidating the rapid rapprochement between Paris and Rabat. At almost the same time, Algerian President Abdelmadjid Tebboune was in Berlin seeking to deepen Algeria’s partnership with Germany. Four days later, Spanish Prime Minister Pedro Sanchez arrived in Algiers, continuing efforts to repair relations strained by Madrid’s shift towards Morocco.

The principal fault line in the rivalry is Western Sahara. Morocco controls most of the territory and has made support for its sovereignty claim, or its autonomy proposal, a central test of its foreign partnerships. Algiers backs the Polisario Front’s demand for independence and has responded sharply when European governments endorse Rabat’s position on the territory.

European governments cannot therefore manage the two relationships in isolation. Decisions that strengthen ties with one can reshape their diplomatic, economic and security cooperation with the other.
