Morocco vs Algeria: The Frozen Conflict Reshaping North Africa

No shots fired. No peace talks scheduled. The Morocco-Algeria rivalry is the continent's most consequential cold war you rarely read about.

In August 2021, Algeria severed diplomatic ties with Morocco. No ambassadors have been exchanged since. The land border between the two countries has been closed since 1994. In September 2024, Algeria went further and imposed visa requirements on Moroccan citizens. Two countries that share a 1,900-kilometre border, a language, a religion, a colonial history, and a continent have not been able to hold a serious diplomatic conversation in over three years.[1]

The standoff is often framed as a dispute over the Western Sahara. That framing is true but incomplete. The Western Sahara question is the trigger, the justification, and the public face of a rivalry that runs much deeper: a competition for regional leadership between two large, proud nations that both believe they are the natural centre of gravity in North Africa and the Sahel. Understanding that competition is essential to understanding North African geopolitics, European energy security, and the future of the Sahel.

The Roots of the Rivalry

Morocco and Algeria were allies during their respective independence struggles. They fought together, supported each other, and shared a vision of a post-colonial North Africa. The relationship began to deteriorate almost immediately after independence.

In 1963, just a year after Algerian independence, the two countries fought the Sand War over disputed border territories, a conflict that left lasting mistrust on both sides. The Western Sahara dispute, which began after Spain withdrew from its colony in 1975, deepened the division. Morocco marched 350,000 civilians into the territory, establishing administrative control. Algeria backed the Polisario Front, the independence movement that claims the territory as the Sahrawi Arab Democratic Republic. That core disagreement has never been resolved.[2]

What has changed since 2021 is the intensity and the reach of the competition. Both countries have increasingly used trade, energy infrastructure, migration policy, and African diplomacy as instruments of their rivalry, extending what was once a largely bilateral dispute into a contest that now shapes relations from the Sahel to southern Europe.[3]

The Military Dimension: An Accelerating Arms Race

The numbers are striking. Morocco allocated $13 billion to defence in 2025, pursuing F-35 fighter jets, upgrading F-16s, and acquiring the HIMARS precision-strike artillery system.[1] Algeria allocated $18.5 billion, making it Africa's largest military spender. Together, the two countries account for roughly 90 percent of all military spending across North Africa, according to the Stockholm International Peace Research Institute.[4]

Algeria has been Russia's top arms client in Africa for years, purchasing Su-57 fighters, S-400 air defence systems, and multiple launch rocket systems. Morocco, as a designated major non-NATO ally of the United States, has been moving in the opposite direction: toward Western platforms and Israeli technology, including armed drones that it has deployed against Polisario positions in the Western Sahara.[5]

The arms race is not merely symbolic. It consumes resources that could be directed toward the genuine development challenges facing both countries, and it creates structural pressure on both governments to maintain the rivalry rather than resolve it.

The Energy Dimension: Pipelines as Geopolitical Weapons

Energy has become one of the most consequential arenas of the Morocco-Algeria competition. In October 2021, Algeria declined to renew the contract for the Maghreb-Europe gas pipeline, which had carried Algerian gas through Morocco to Spain since 1996. The decision cut Morocco out of transit revenues and signalled that Algeria was willing to use energy infrastructure as a diplomatic instrument.[6]

The two countries are now backing competing pipeline projects that run through the heart of West Africa. Algeria has revived the Trans-Saharan Gas Pipeline, a 4,128-kilometre project designed to carry up to 30 billion cubic metres of Nigerian gas annually through Niger and Algeria to European markets. In early 2026, Algeria's President Tebboune met with Niger's military leader and committed to the pipeline's immediate relaunch, a move designed directly to counter Morocco's positioning.[7]

Morocco, for its part, is championing the Nigeria-Morocco Gas Pipeline, an Atlantic-facing project that would carry Nigerian gas along the West African coastline to Morocco and then to Europe via existing Spain-Morocco infrastructure. Morocco also launched the Atlantic Initiative in 2023, positioning itself as a transit hub and logistics gateway for landlocked Sahelian states seeking access to Atlantic trade routes.[3]

"Morocco and Algeria are pursuing distinct, calculated strategies to position themselves as dominant powers. In doing so, they risk exporting their rivalry to already volatile regions like the Sahel." - EST Think Tank, July 2025

The Carnegie Endowment's July 2025 analysis frames this well: both countries are now using trade and the energy sector to project power, forge new alliances, and engage in strong-arm tactics against European governments. Spain, caught between Algerian gas supply and Moroccan migration cooperation, has consistently found itself squeezed. France, which backed Morocco's Western Sahara position in 2024, found Algeria boycotting French wheat in 2025.[3]

The Sahel Dimension: Where the Competition Gets Dangerous

Perhaps the most consequential arena of the Morocco-Algeria rivalry in 2025 and 2026 is the Sahel. The region's instability has created a vacuum that both countries are trying to fill, with very different approaches and very different alignments.

Algeria has historically positioned itself as a mediator in Sahelian conflicts, having brokered peace agreements in Mali and maintained relationships across the region. But its influence has been eroding. Algeria opposes the presence of Russian Wagner and Africa Corps fighters in the Sahel, a stance that has damaged its relationships with the military juntas in Mali, Burkina Faso, and Niger. By early 2026, Algeria had been largely sidelined from the Alliance of Sahel States.[1]

Morocco has moved to capitalise on that opening. The Atlantic Initiative gives Sahelian states an alternative trade corridor. Morocco has been strengthening bilateral ties with West African governments and positioning itself as a partner for countries that want access to Atlantic markets rather than Mediterranean routes controlled by Algeria. The irony is that Morocco and the junta-led AES states are unlikely bedfellows politically. But shared interest in countering Algeria's influence has created a working alignment.[3]

Algeria tried to form a competing regional bloc with Tunisia and Libya in 2024, holding a high-level tripartite summit in Tunis as a direct counterweight to Moroccan influence. But that bloc remains weak and internally divided. Libya's fractured governance makes it an unreliable partner, and Tunisia's economic difficulties limit its strategic capacity.[8]

The Cost of the Frozen Conflict

The Morocco-Algeria standoff has real costs that are measured in more than military budgets. The LSE Africa blog's September 2025 analysis puts it plainly: the bilateral standoff affects broader African development aspirations. The two countries together represent significant economic weight in North Africa, and their inability to cooperate limits what is achievable on the continent.[4]

The Arab Maghreb Union, the regional integration body established in 1989, has been effectively non-functional for three decades precisely because of this rivalry. A functioning Maghreb economic community could generate enormous benefits for both countries through trade, infrastructure, and joint energy development. Instead, both governments invest in an arms race that serves neither population.

The Middle East Institute's November 2025 analysis argues that reconciliation between the two countries is both possible and in both countries' strategic interest, but that it requires a dual narrative that allows both governments to claim domestic victory from the same agreement. That is a genuinely hard diplomatic problem. Neither the Moroccan monarchy nor the Algerian military leadership can afford to be seen as backing down.[1]

The Morocco-Algeria rivalry is not going to be resolved by external pressure or by the logic of economic interest alone. It has become embedded in both countries' domestic politics, military planning, energy strategy, and regional diplomacy. Resolving it would require political courage from two governments that have both built legitimacy partly on the rivalry itself. That is a difficult thing to ask. But the alternative is a North Africa that continues to divert its enormous human and natural resources into a competition that serves the strategic interests of external powers far more than it serves the 85 million Moroccans and Algerians who live with its consequences.
