President Jacob Zuma will lead a South African delegation to a special meeting of the Southern African Development Community's (SADC's) security troika in Dar es Salaam, Tanzania on Thursday.
Zuma is attending the meeting in his capacity as chair of the SADC's Organ on Politics, Defence and Security Cooperation.
He will be joined by Namibian President Hifikepunye Pohamba, Tanzanian President Jakaya Kikwete and Mozambique President Armando Guebuza, who together make up the organ.
High on Thursday's agenda will be reports on recent political and security developments in the Democratic Republic of Congo (DRC) and Madagascar, as well as Zimbabwe's elections.
South Africa's Department of International Relations and Cooperation said the 15-nation SADC was still the primary vehicle for South Africa to promote regional development and integration within the southern African region.
"South Africa has a vested interest in seeing the regional political and security situation improve, which will create positive conditions for the improvement of the quality of life of South Africans and SADC citizens in general," the department said in a statement on Wednesday.
Zuma will be accompanied by International Relations Minister Maite Nkoana-Mashabane, who is already in Dar es Salaam for a meeting of the ministers involved in the body.
