Relations between Nigeria and its northern Sahel neighbour Niger have been tense since the military took over in Niamey in 2023 and broke away from the regional bloc ECOWAS.

Nigeria's President Bola Ahmed Tinubu, who is head of the Economic Community of West African States, initially took a hardline but has since been trying to persuade the three junta-led states Niger, Mali and Burkina Faso to return to the group.

Nigeria's chief of defence staff General Christopher Musa on Wednesday met in Niamey with General Moussa Salaou Barmou to discuss security cooperation, a Nigerian military statement said.

"Both parties reaffirmed their commitment to resuming and strengthening collaboration, with a view to ensuring regional stability and security," it said on Thursday.

The statement said Niger's chief of staff would visit Nigeria to finalise cooperation and a Niger advisory group would be created to improve communication between the two militaries.

"Niger affirmed its readiness to resume active participation in security cooperation under the Multinational Joint Task Force (MNJT)," the statement said.

The task force, involving Nigeria, Niger, Cameroon and Chad, has been key in battling jihadists active along the border areas of the four countries.

Niger's military government is battling jihadists linked to the Islamic State group, Al-Qaeda and Boko Haram in the western Tillaberi region and in southeastern Diffa area near Nigeria.
