South African Deputy President David Mabuza arrived in Sudan on Thursday for talks with the President of the Transitional Sovereign Council of the Republic of Sudan, Gen Abdalftah Alburhan A. Alrahman over the situation in South Sudan.

Mabuza’s trip to Khartoum comes following another meeting with President Yoweri Museveni in Uganda regarding the implementation of the Revitalised Agreement on the Resolution of Conflict in South Sudan (R-ARCSS).

Mabuza said his meeting with President Museveni was fruitful and that the two would continue with efforts to ensure the peace process in South Sudan moves forward.

“In my meeting with President Museveni we further committed to working together in ensuring that the parties to the agreement stay on course and are supported in their efforts of making this peace process a success. We are confident that when parties work together for the good of South Sudan, substantive progress will be made in this window period thereby silencing the guns and building lasting peace in South Sudan.”said Deputy President Mabuza.

Earlier this month, Mabuza made a three-day visit to Juba, during which he facilitated a Consultative Meeting of the Parties to the Revitalized Agreement on the Resolution of Conflict in South Sudan. The Consultative Meeting was on the contentious issue of the number of states and their boundaries.

While in Khartoum, he is expected to also brief President Alrahman on the outcomes of the Consultative Meeting of Parties, and to mobilize support from the guarantor in ensuring that signatories to the R-ARCSS reach a workable agreement on the matter of States and their Boundaries.

South Sudan descended into war in December 2013, sparked by a feud between President Kiir and his then-deputy Machar.

Kiir accused Machar of plotting to overthrow his rule, but the latter denied the allegations though he went on to mobilize a rebel movement to fight the government.

The war has killed hundreds of thousands and displaced millions, prompting the United Nations to rank the country as Africa’s biggest refugee crisis.

With pressure from regional and international actors, Kiir and Machar are locked in talks aimed at returning lasting peace to the country.
