Lourenço who is also the Chair of the International Conference on the Great Lakes Region (ICGLR) is the mediator on tensions between Rwanda and DRC.
The meeting takes place at a time when DRC continues to accuse Rwanda of backing M23 rebel group during clashes with Congolese Army (FARDC).
However, Rwanda has rejected the allegations and advised the neighbouring country not to drag it into internal problems.
The Chairperson of the African Union Commission, Moussa Faki Mahamat recently revealed that the eastern part of DRC has for long turned into a concentration area for terrorist groups, a situation which required interventions from the United Nations and neighbouring countries to find a solution.
He said that the situation was promising based on cordial relations between Rwanda and DRC since 2018, but has deteriorated again.
Mahamat further disclosed that the issue was discussed in Malabo, Equatorial Guinea, during an extraordinary Summit of the African Union where President Joao Lourenço was designated as a mediator.
