The Economic Community of West African States (ECOWAS) has significantly strengthened its diplomatic approach concerning the Alliance of Sahel States (AES). During a recent ordinary summit held in Lungi, Sierra Leone, West African leaders established a pivotal principle: no member state will henceforth be permitted to engage in separate discussions with Mali, Burkina Faso, or Niger on critical regional matters. This decisive action aims to safeguard the cohesion of a regional bloc that has faced considerable strain since the three Sahelian nations officially announced their withdrawal, effective January 2025.

The imposition of a singular communication channel reflects palpable concern within Abuja. Since the formalization of the AES into a confederation, several regional capitals had shown inclinations towards establishing pragmatic arrangements with their Sahelian neighbors, particularly concerning free movement, security cooperation, and trade exchanges. By restricting the format for engagement, ECOWAS seeks to prevent its declared solidarity from eroding due to immediate national interests.

A common front to strengthen negotiating power

This strategy of a unified bloc is designed to enhance its negotiating influence. In response to an AES that has built its narrative around sovereignist rupture and a challenge to regional oversight, ECOWAS is leveraging the collective weight of its remaining members to protect its integration achievements. Key sensitive areas, such as the common external tariff, the free movement of people, and the preferential trade regime, are particularly vulnerable, as their undermining would jeopardize half a century of regional construction.

However, this collective approach carries a potential drawback. By prohibiting bilateral channels, the organization risks a prolonged stalemate if internal consensus proves elusive. Coastal states, notably Sénégal, Côte d’Ivoire, and Togo, maintain deep economic and human ties with the Sahelian capitals. Their vital logistical corridors serve landlocked economies, whose stability is intrinsically linked to their own.

The AES consolidates its autonomous trajectory

On the other side, the Alliance of Sahel States continues to build its institutional framework. With a confederal passport, efforts towards a common currency, and an announced joint force of 5,000 personnel to combat jihadist groups, Bamako, Ouagadougou, and Niamey are clearly demonstrating their resolve to construct a credible alternative entity. Diplomatic rapprochement with nations like Russia, Turkey, and Iran further contributes to this geopolitical realignment, reshaping West African power dynamics.

In this evolving context, ECOWAS’s stance represents both a firm boundary and an outstretched hand. The heads of state present in Lungi reaffirmed their desire to maintain structured dialogue with the AES on issues vital for populations, including human mobility and cross-border trade. However, they intend to conduct this dialogue according to their own established rules, rather than those dictated by the Sahelian party.

Concrete issues awaiting resolution

Several technical disputes are awaiting arbitration. The status of Sahelian nationals residing within the ECOWAS space, the customs regime applicable to goods originating from the AES, the management of shared infrastructure like the Niger Basin Authority, and the mutual recognition of academic qualifications all represent significant challenges where a lack of agreement would swiftly penalize economic actors and citizens alike.

The specific timeline for negotiations was not officially disclosed following the summit. According to West African diplomats, a technical commission is expected to be mandated to prepare the terms of engagement with Bamako, Ouagadougou, and Niamey. The current chair, Sierra Leone, will bear the responsibility of conveying this unified message to the Sahelian authorities.

A delicate political equation remains. Several member countries, including Sénégal under President Bassirou Diomaye Faye, have recently advocated for a more conciliatory approach towards the AES, arguing that isolating the Sahelian regimes would be counterproductive. The collective discipline enforced at Lungi must now withstand these divergent sensitivities, lest it become an ineffective declaration.
