Algeria vs Spain

About this relationship

Spain and Algeria have maintained diplomatic relations since Algeria's independence from France in 1962, a relationship shaped from the outset by geographic proximity across the western Mediterranean, historical Spanish colonial holdings in North Africa, and the long-running dispute over Western Sahara, a former Spanish colony whose decolonization Madrid left unresolved when it withdrew in 1975-76. Algeria, as the principal backer of the Polisario Front seeking Western Saharan self-determination, has treated Spain's position on the territory as a litmus test of the bilateral relationship for decades, while Spain has also developed Algeria into one of its most important energy suppliers and a key partner on migration management across the Mediterranean and Atlantic routes. Substantial Algerian emigration to Spain, alongside a long-standing Spanish community historically present in Algeria, has added a demographic dimension to ties that intersect with both labor markets and irregular migration flows monitored by both governments.

The relationship suffered its most serious rupture in recent memory in March 2022, when Spain's government under Pedro Sánchez shifted its long-standing neutral position on Western Sahara to back Morocco's autonomy plan for the territory, a move Algeria condemned as a betrayal; Algiers recalled its ambassador from Madrid and, in June 2022, suspended its 2002 Treaty of Friendship, Good-Neighborliness and Cooperation with Spain and halted commercial transactions with Spanish companies, prompting European Parliament scrutiny of what was characterized as a trade boycott. Relations remained frozen and commercially strained for several years before a gradual, pragmatic thaw took hold. In July 2026, Sánchez traveled to Algeria for the first time in four years as the two governments sought to formally reset ties, and the two sides subsequently agreed to hold an 8th Spain-Algeria High-Level Meeting in October 2026 to institutionalize the reengagement across political, economic and security tracks.

Energy has remained the backbone of the economic relationship throughout even the coldest periods of the diplomatic dispute, underscoring both countries' mutual dependence. Algeria supplies Spain with natural gas primarily via the Medgaz undersea pipeline linking Béni Saf to Almería, a route that gained added strategic weight after Algeria closed the older Maghreb-Europe pipeline running through Moroccan territory in October 2021 amid its own rupture with Rabat; reporting in 2026 indicated Algeria remained Spain's leading gas supplier over the preceding twelve months, reflecting Spain's efforts to diversify away from Russian energy since 2022. Beyond hydrocarbons, bilateral trade covers agri-food products, machinery, construction and engineering services, with Spanish firms historically active in Algerian infrastructure and energy-sector contracts, though the 2022-2025 rupture disrupted commercial transactions and payment channels for a period, a disruption both governments have sought to fully unwind through the renewed high-level dialogue.

Security cooperation between Spain and Algeria centers on counter-terrorism intelligence sharing, maritime border control in the western Mediterranean, and coordination on irregular migration departing from Algerian shores toward the Spanish coast and the Balearic Islands, an issue that has grown in salience as migratory routes have shifted. Both countries engage multilaterally through the Union for the Mediterranean and NATO's Mediterranean Dialogue framework, in which Algeria participates as a partner rather than a member. Cultural and human ties remain significant given the sizeable Algerian community resident in Spain, concentrated in regions such as Catalonia and the Valencian Community, alongside historic Spanish-Algerian ties in Oran and other coastal cities where a Spanish-descended population once resided prior to independence. By 2026, Spain-Algeria relations have moved decisively from post-2022 rupture toward pragmatic reengagement, with energy interdependence and migration management anchoring a relationship still shaped by the unresolved Western Sahara question.
