The leaders of French-speaking countries have held a summit on the Tunisian island of Djerba to discuss growing instability in parts of Francophone Africa - including in parts of the Sahel and the east of the Democratic Republic of Congo.
The head of the group, Louise Mushikiwabo, said there had been long discussions about the main conflict zones.
She said the group could support and quicken efforts "to mediate between parties in conflict".
DR Congo Prime Minister Jean-Michel Sama Lukonde refused to pose for a group photo next to Rwandan President Paul Kagame.
Kinshasa has accused him of supporting M23 rebels fighting in the east.
Rwanda has always denied the allegations.
