President Jacob Zuma will visit the Republic of Congo this week, the presidency said on Sunday.

"President Zuma will attend the celebrations of the 25th anniversary of the signature of the Brazzaville accord on peace in Southern Africa," the presidency said.

The event, which will be held on Tuesday, marks the end of the Brazzaville negotiations, which ended the Angolan civil war with the signing of the Brazzaville Protocol on December 22, 1988.

The occasion also prepared the ground for the independence of Namibia and ultimately South Africa.

Zuma was invited to attend the anniversary by Congo President Dennis Sassou-N'guesso.

"South Africa continues to enjoy cordial bilateral relations with the Republic of Congo.

"The formal relations between the two countries are structured through the Joint Commission of Co-operation as a mechanism to monitor and guide the implementation of agreements," said the presidency.

Zuma would be accompanied by Minister of International Relations and Cc-operation Maite Nkoana-Mashabane.
