Sierra Leone vs. Guinea

Sierra Leone opposes Guinean troops' continued occupation of Yenga, a small village on the Makona River that serves as a border with Guinea; Guinea's forces came to Yenga in the mid-1990s to help the Sierra Leonean military to suppress rebels and to secure their common border but have remained there even after both countries signed a 2005 agreement acknowledging that Yenga belonged to Sierra Leone; in 2012, the two sides signed a declaration to demilitarize the area

Sierra Leone considers Guinea's definition of the flood plain limits to define the left bank boundary of the Makona and Moa Rivers excessive and protests Guinea's continued occupation of these lands, including the hamlet of Yenga, occupied since 1998
