Motlanthe will lead a delegation from the Southern African Development Community (SADC) that includes former president and mediator Thabo Mbeki and Mozambique’s President Armando Emilio Guebuza.
"The delegation will include President Guebuza of Mozambique and former South African President Thabo Mbeki, the facilitator in the Zimbabwe Inter-Party Dialogue," the statement from the president’s office said Thursday.
Negotiating teams are also to meet to discuss issues related to a deadlocked power-sharing deal signed some four months ago, it said.
Talks are to include discussion on a constitutional amendment creating the posts of prime minister and deputy prime minister, which are to be filled by opposition Movement for Democratic Change (MDC) leader Morgan Tsvangirai and Arthur Mutambara, the head of an MDC splinter group.
The meeting of the negotiating teams was initially scheduled for Friday, January 16 but had to be postponed at the request of one of the parties, the statement also said.
