West African bloc unites against Sahel alliance with no bilateral talks allowed

The Economic Community of West African States (ECOWAS) has adopted a firmer diplomatic stance against the Alliance of Sahel States (AES). During the recent ordinary summit held in Lungi, Sierra Leone, regional leaders established a clear guideline: no member state may pursue separate discussions with Mali, Burkina Faso, or Niger on key regional matters. This decision aims to uphold the unity of a bloc already strained since the three Sahelian nations officially withdrew in January 2025.

The decision to centralize negotiations reflects growing concerns in Abuja. Since the AES formalized its confederation, several West African capitals have explored pragmatic arrangements with their Sahelian neighbors, particularly on security cooperation, free movement, and trade. By locking in a unified approach, ECOWAS seeks to prevent the erosion of solidarity in favor of short-term national interests.

Unified front to strengthen negotiating power

This collective strategy is rooted in leveraging the bloc’s combined influence. Faced with an AES that has built its identity on sovereign defiance and rejection of regional oversight, ECOWAS is banking on the aggregate strength of its remaining members to safeguard decades of regional integration. Critical issues such as the common external tariff, free movement of people, and preferential trade regimes are at stake—each could destabilize half a century of regional progress if compromised.

Yet this unified approach carries risks. By banning bilateral channels, ECOWAS risks prolonged deadlock if internal consensus proves elusive. Coastal states, particularly Senegal, Côte d’Ivoire, and Togo, maintain deep economic and human ties with Sahelian capitals. Their logistical networks serve landlocked economies whose stability directly impacts their own.

Sahel alliance pushes ahead with autonomous agenda

Across the negotiating table, the AES continues to solidify its institutional framework. Plans for a confederation passport, a proposed common currency, and a joint 5,000-strong force to combat jihadist groups underscore Bamako, Ouagadougou, and Niamey’s commitment to building a credible alternative bloc. Diplomatic outreach to Moscow, Ankara, and Tehran further reshapes West Africa’s geopolitical landscape.

In this evolving context, ECOWAS’ position serves as both a red line and an olive branch. Leaders at the Lungi summit reaffirmed their openness to structured dialogue with the AES on critical issues like cross-border mobility and trade. However, they insist such discussions proceed on ECOWAS’ terms—not imposed by the Sahelian alliance.

Pending technical disputes

Several unresolved issues demand resolution. The status of Sahelian nationals living within ECOWAS territory, customs regulations for goods originating from AES member states, shared infrastructure management such as the Niger Basin Authority, and mutual recognition of academic credentials all represent flashpoints that could quickly disrupt economic actors and citizens alike.

No official negotiation timeline was disclosed following the summit. However, diplomatic sources indicate a technical commission will be tasked with drafting engagement terms with Bamako, Ouagadougou, and Niamey. Sierra Leone, holding the rotating presidency, will bear the responsibility of presenting this unified stance to Sahelian authorities.

A delicate political equation remains. Several member states, including Senegal under President Bassirou Diomaye Faye, have advocated for a more conciliatory approach toward the AES, arguing that isolating Sahelian regimes would prove counterproductive. The collective discipline imposed in Lungi will now be tested against these divergent viewpoints—or risk fading into mere rhetoric.
