Algerian Prime Minister Sifi Ghrieb and Nigerien Prime Minister Ali Lamine Zeine Mahaman signed over 20 strategic agreements in Niamey on March 24, 2026, to formalise a diplomatic reconciliation between the two neighbouring states.
The high-level summit concludes a period of strained relations that began in April 2025. This “cold war” was sparked when Algerian air defences shot down a Malian-operated Bayraktar Akinci drone near the border town of Tinzaouaten, prompting Niger and its allies in the Alliance of Sahel States (AES) to recall their ambassadors. Normalisation began in earnest on February 12, 2026, with the reciprocal return of ambassadors, followed by a state visit to Algiers by Nigerien President Abdourahamane Tchiani.
The new agreements cover a broad spectrum, including energy, security, health, and infrastructure. Both leaders described the partnership as “irreversible” and “strategic,” emphasising that the security of both nations is closely interconnected. The 2026 summit serves as the second session of the Algeria-Niger High Joint Commission, with a third session already scheduled for 2027 in Algiers to monitor progress on these commitments.
Energy and infrastructure priorities
Energy cooperation is the primary driver of this renewed alignment. A central component is the immediate relaunch of the Trans-Saharan Gas Pipeline (TSGP), a $13 billion project designed to transport 30 billion cubic meters of natural gas annually from Nigeria through Niger to Algeria’s Mediterranean coast. Technical operations for the 4,127-kilometre pipeline are scheduled to resume following the conclusion of Ramadan in early April 2026.
The summit also addressed Niger’s immediate energy deficit. Algeria committed to constructing a 40-megawatt power plant near Niamey to reduce Niger’s reliance on electricity imports, which historically accounted for 70% of its supply. Additionally, Algeria’s state-owned energy company, Sonatrach, will resume drilling at the Kafra oil block in northern Niger by early April. The Kafra field, covering over 23,000 square kilometres, has estimated reserves exceeding 260 million barrels and a potential output of 90,000 barrels per day.
Beyond hydrocarbons, the bilateral roadmap fast-tracks the Trans-Saharan Highway and a cross-border fibre optic link. These “structuring projects” are intended to provide landlocked Niger with improved transit corridors while securing Algeria’s southern frontier through economic integration. The technical specifications of these projects prioritise regional connectivity as a countermeasure to the economic isolation previously faced by the Niamey administration.
The rapprochement carries significant security implications for the Sahel-Sahara region. By reactivating bilateral security mechanisms and intensifying joint border surveillance, Algiers and Niamey aim to coordinate responses to terrorism and transnational organised crime. This move suggests a shift toward locally led security solutions, moving away from reliance on non-regional actors.
The resumption of the TSGP and the Kafra oil project indicates that economic pragmatism has overtaken the diplomatic friction of 2025. For Algeria, the deal solidifies its role as a regional energy hub for Europe. For Niger, the partnership provides critical infrastructure and revenue streams necessary for domestic stability. Further technical evaluations of the Kafra drilling sites and the first phase of pipeline laying are expected to commence within the next 30 days.
