While Niamey maintains a closed border with Bénin, citing security guarantees, the evolving relationship between Chad and France presents a complex question for Niger. If a French military presence in a neighboring country is deemed a threat sufficient to justify border closure, should this same logic extend to Chad?

The border between Niger and Bénin remains sealed. Nearly three years after the July 2023 coup, the anticipated normalization between Niamey and Cotonou has yet to result in the actual reopening of this crucial communication route.

Despite this, signs of easing tensions have emerged in recent months. Both nations have re-engaged in dialogue and established a technical framework tasked with examining the conditions for reopening. Discussions have also advanced on security, economic, and legal aspects.

However, Niamey continues to uphold its demands.

In a recent public address, General Abdourahamane Tiani articulated that the border’s reopening must be contingent upon guarantees, specifically concerning security and the absence of forces perceived as hostile near the frontier. This stance aligns with the position advocated by Nigerien authorities for several years: Niamey asserts that Béninese territory must not serve as a platform for operations that could jeopardize Niger’s security.

The core issue is that Cotonou vehemently disputes this accusation.

Cotonou denies, Paris also

Since the onset of the crisis, Béninese authorities have consistently rejected allegations that France operates military bases within Bénin, particularly in the northern regions.

The Béninese government affirms it has never hosted any foreign military base on its soil. Bénin’s Minister of Foreign Affairs, Olushegun Adjadi Bakari, reiterated this position in January 2025.

Paris has similarly refuted the existence of a French military base in northern Bénin. In March 2026, the French Chief of Staff, General Fabien Mandon, dismissed these accusations, assuring that no French base existed in that part of the country.

Nevertheless, a crucial distinction warrants clarification.

France does provide a form of security support to Bénin. French military personnel have participated in training programs and offered assistance to Béninese forces confronting armed groups in the country’s north. Reports in April 2026 detailed the discreet presence of French special forces operating alongside Béninese troops. Officially, French authorities refer to these personnel as trainers.

Therefore, it is essential to differentiate between Franco-Béninese military cooperation, which is acknowledged, and the existence of a French military base or a permanent French deployment near the Nigerien border, which both Cotonou and Paris deny.

It is precisely this distinction that forms a central part of the ongoing debate.

An exigency that presents Niamey with a new equation

Indeed, as Niger demands guarantees from Bénin, another neighbor of Niger is rekindling ties with Paris.

In November 2024, Chad had previously ended its military cooperation with France, asserting its commitment to fully exercise its sovereignty and diversify its security partnerships.

The French withdrawal was then portrayed as a significant turning point in relations between N’Djamena and Paris.

However, over several months, the two capitals have once again grown closer. French military personnel are gradually returning to Chad, operating under a far more discreet and scaled-down arrangement than the previous one.

This development addresses pressing security realities: Chad grapples with the repercussions of the conflict in Sudan, the persistent threat from Boko Haram in the Lake Chad basin, and substantial requirements for intelligence, surveillance, and logistical capabilities.

N’Djamena may thus interpret France’s return as a sovereign and pragmatic decision.

Yet, for Niamey, this choice raises a critical question.

Chad, too, shares a border with Niger.

Consequently, if Niamey considers a French military presence near its territory a sufficiently grave threat to prevent the reopening of its border with Bénin, how does Niger intend to respond to the Franco-Chadian rapprochement?

Why would Chad be different from Bénin?

Herein lies the true paradox.

Niamey could logically assert that every state is free to choose its military partners. Under this reasoning, Bénin would have the right to cooperate with France, and Chad would similarly have the right to renew its partnership with Paris.

However, if this logic holds, it should also lead Niger not to make Franco-Béninese cooperation a decisive condition for reopening its border.

Conversely, if Niamey genuinely believes that French military cooperation with a neighbor constitutes a threat to its national security, then the same reasoning should, by all accounts, be applicable to Chad.

The question, therefore, is not whether Niger should close its border with Chad.

Rather, it is about testing the consistency of its stated arguments.

Why would military cooperation with France be deemed unacceptable for Niger’s western neighbor, yet acceptable for its eastern neighbor?

Geography makes this question particularly sensitive. Niger shares extensive borders with both Bénin and Chad. A foreign military presence in Chad could, theoretically, be considered part of Niamey’s immediate strategic environment.

France’s return to Chad, a test for the sovereignist doctrine

The Chadian situation unfolds within a profoundly transformed regional context.

Mali, Burkina Faso, and Niger have elevated sovereignty and a break from former partner powers as foundational pillars of their new foreign policy. These three nations have withdrawn from ECOWAS and intensified their cooperation within the Alliance of Sahel States.

Chad, conversely, has opted for a distinct trajectory.

After ending its partnership with Paris in 2024, N’Djamena now appears keen to resume military cooperation with France, while simultaneously maintaining its other partnerships.

This choice is sovereign.

However, it might prove challenging to reconcile with a conception of sovereignty that would deny neighbors the right to choose their own partners.

Thus, it is less the French presence in Chad than the principle of consistency that currently anchors this debate.

Towards a resolution between Niamey and Cotonou?

The situation, however, could evolve.

Ongoing discussions between Niger and Bénin indicate that both countries recognize the economic and security costs associated with their border closure. For nearly three years, populations, traders, and transporters in the border zone have borne the brunt of a political crisis that far transcends their local interests.

Furthermore, violence in the border area shared by Bénin, Niger, and Nigeria has significantly escalated, underscoring the mutual benefit of enhanced security cooperation between the two nations.

A border reopening could, therefore, become a shared imperative.

Yet, to achieve this, Niamey and Cotonou will likely need to move beyond the issue of France.

The debate cannot indefinitely remain confined to an opposition between ‘French presence’ and ‘African sovereignty.’

If Niger seeks security guarantees from Bénin, it can legitimately request them. However, these guarantees must be grounded in verifiable facts, transparent mechanisms, and reciprocal commitments.

Crucially, they must be applied according to the same principles to all neighboring states.

The gradual resumption of French military cooperation in Chad thus adds a new dimension to this crisis.

Niamey is now faced with a choice: either acknowledge that every sovereign state is free to select its partners, or uphold a doctrine where French military cooperation with a neighbor constitutes a threat justifying retaliatory measures.

In the former scenario, reopening the border with Bénin could be facilitated.

In the latter, the rapprochement between N’Djamena and Paris risks presenting Niger with a question that will be difficult to sidestep: if France poses a threat in Bénin, why would it not in Chad?

Perhaps within this apparent contradiction lies one of the primary challenges for Sahelian diplomacy today: ensuring that sovereignty is a principle applicable to all, rather than an instrument wielded selectively based on power dynamics between neighboring states.
