much of Benin-Niger boundary, including tripoint with Nigeria,
remains undemarcated but states accept 2001 arbitration over

signatories Cameroon, Chad, Niger, and Nigeria to ratify
delimitation treaty over the lake region, which remains the site of
armed clashes among local populations and militias
