Talks are under way in the capital of the Democratic Republic of Congo aimed at resolving a diplomatic row with Rwanda and halting a violent conflict in the east of the country.
Angola's President João Lourenço and the former Kenyan leader Uhuru Kenyatta are mediating between representatives of the two governments.
This follows a meeting on Friday with Rwanda's President Paul Kagame.
He has denied backing the M23 rebel group that recently re-launched an offensive which has left tens of thousands of people displaced.
The mediators will also speak to victims of the conflict.
DR Congo's government is due to meet representatives of various armed groups later this month in the Kenyan capital Nairobi.
