The Alliance of Sahel States (AES)—comprising Burkina Faso, Mali, and Niger—is entering a more consequential phase. What began in 2023 as a mutual-defence arrangement has evolved into a confederation seeking its own institutions, security architecture, economic mechanisms, and diplomatic identity.
The latest developments show that the AES is no longer simply a political protest against the Economic Community of West African States (ECOWAS). It is increasingly attempting to build an alternative regional framework.
The AES is moving from a political and military alliance toward a more institutionalised regional bloc. Recent developments in September 2026 suggest that Burkina Faso, Mali and Niger are attempting to turn their mutual rejection of the traditional West African order into a functioning alternative—while still facing serious security and economic issues.
1. The AES Is Building Institutions
One of the clearest recent developments remains the effort to strengthen cooperation along the three countries’ shared borders.
In September, AES authorities adopted a roadmap for cross-border cooperation covering security, humanitarian response and economic development. The framework creates more permanent consultation between local authorities and provides for coordinated responses to insecurity, displacement and economic disturbance.
This is significant because the AES’s success will ultimately depend less on political speeches and more on whether it can make cooperation work at the local level.
The bloc has also been developing other common structures, including a joint biometric passport, economic institutions and shared communication platforms. A joint AES television channel, Tafouk TV, began expanding its programming schedule this month, giving the confederation a dedicated platform to communicate its policies and regional identity.
2. Security Remains the Biggest Test
Security remains the AES’s central justification. Yet it is also where the alliance faces its toughest test.
Recent attacks in Mali demonstrate that the jihadist threat has not disappeared despite the military governments’ decision to distance themselves from Western security agreements and deepen alternative alliances.
In September, al-Qaeda-linked JNIM attacked a Malian military position in Dioura. Reuters reported that sources estimated more than 100 Malian soldiers were killed, while the Malian military acknowledged casualties without confirming the higher figures. JNIM also carried out attacks around Sevare airport.
The episode illustrates an uncomfortable reality: institutional sovereignty and military independence do not automatically translate into improved security outcomes.
For the AES, the key question is therefore whether greater coordination between Burkina Faso, Mali and Niger can eventually produce measurable improvements in territorial control, intelligence-sharing and civilian protection.
3. The Break With ECOWAS Is Becoming More Permanent
The three countries formally left ECOWAS on January 29, 2025, after years of political confrontation with the regional organisation.
Since then, the separation has taken on increasingly practical and political forms.
The development of AES passports and other common institutions suggests that the three governments are trying to build a distinct political identity rather than negotiate a return to the previous regional arrangement.
At the same time, ties to the wider West African economy have not disappeared. Research published in the African Development Review suggests that withdrawal from ECOWAS could redirect some trade toward other markets and affect sectors across the three countries, while having relatively limited short-term effects on aggregate household consumption, income, and investment.
This means the economic consequences of the AES experiment are likely to be gradual rather than immediate.
4. Natural Resources Are Becoming Central to the Project
The AES is also increasingly focusing on mining, energy and resource development.
Burkina Faso recently highlighted cooperation among the three countries on mining and energy, while AES-related meetings have focused on better valuing natural resources within the confederation.
This matters because all three countries possess strategically important resources, ranging from gold and uranium to other minerals and hydrocarbons.
The real test will be whether resource nationalism produces domestic processing, employment, infrastructure and government revenue, rather than simply changing which foreign companies participate in extraction.
5. A More Coordinated Foreign Policy
The AES is also trying to speak with a more unified diplomatic voice.
Its foreign ministers have been working on coordinated positions in international organisations and on diversifying external partnerships. The three governments are also coordinating ahead of the 81st United Nations General Assembly.
This represents an important evolution.
Individually, Burkina Faso, Mali and Niger have limited diplomatic and economic leverage. Collectively, they have a larger population, territory, natural-resource base and military significance.
The objective appears to be to convert that combined weight into greater bargaining power with external partners.
6. The International Relations Question Is Getting More Complicated
The AES is simultaneously reducing some traditional Western ties while developing new relationships.
The three governments have moved closer to Russia for security cooperation, while seeking greater autonomy in their diplomatic relationships. At the same time, the bloc is not completely isolated from the wider West African system.
Indeed, Burkina Faso has recently sought bilateral discussions with Nigeria on cooperation, suggesting that leaving ECOWAS does not necessarily imply abandoning relationships with its neighbours.
This distinction is important. Regional integration and ECOWAS membership are no longer necessarily synonymous.
7. The Democratic and Human-Rights Question
Another important development is the AES governments’ changing relationship with international institutions.
In July 2026, Burkina Faso, Mali and Niger formally began the process of withdrawing from the International Criminal Court. The ICC confirmed that the withdrawal process would take one year.
Supporters of the sovereignty-focused approach can view this as another assertion of national independence. Critics, including Amnesty International, have argued that withdrawal could weaken paths for accountability for serious international crimes.
The debate therefore goes beyond geopolitics. It raises fundamental questions about how the AES intends to balance sovereignty, security, civilian rights and international accountability.
What This Means for Nigeria and West Africa
For Nigeria and the wider region, the emergence of the AES creates a new geopolitical reality.
The old West African assumption—that ECOWAS would remain the principal framework for regional political and economic integration—no longer explains developments in the Sahel.
Nigeria must now manage two realities simultaneously: ECOWAS remains an important regional institution, while the AES is developing an alternative political and security structure on Nigeria’s northern and western periphery.
The implications extend to counterterrorism, border management, migration, trade, energy, mining and diplomatic relations.
Most importantly, insecurity does not respect institutional boundaries. Militancy, weapons trafficking, displacement and organised crime can move between the AES countries and coastal West African states regardless of which regional organisation a country belongs to.
Round Up
The AES experiment has entered a decisive phase.
Its first stage was about political separation—rejecting aspects of the existing regional order and asserting sovereignty.
Its second stage is about institution-building—creating passports, common diplomatic mechanisms, economic structures, media platforms and cross-border governance.
Outcomes will judge the next stage.
Can the AES reduce insecurity? Can it create economic opportunities? Can it transform its mineral wealth into productive industries? Can it maintain workable relations with neighbouring countries? And can it provide effective institutions and accountability as it pursues greater sovereignty?
Those questions will determine whether the AES becomes a durable model of regional integration or remains primarily a political expression of the Sahel’s dissatisfaction with the old order.
For now, the most important update is that the AES is becoming more institutional—but its greatest challenge remains converting institutional ambition into concrete improvements in security, economic welfare and governance.
