Representatives of Rwanda and the Democratic Republic of Congo have reached a draft agreement that could end decades of conflict.
The breakthrough, mediated by the US and Qatar, provides for the "disengagement, disarmament and conditional integration" of armed groups fighting in eastern DR Congo.
It also includes provisions for a joint security mechanism to prevent future flare-ups. The peace deal is expected to be formally signed next week.
The deal could open the way for billions of dollars of western investment in the mineral-rich region, which been plagued by conflict for three decades.
However, analysts say that many questions still remain about the contents of the peace deal.
