South African President Cyril Ramaphosa is set to host his counterparts from Brazil, Russia, India and China on Wednesday when he opens the 10th Brics summit taking place in Sandton, Johannesburg, the presidency said in a statement.

The summit is taking place under the theme "Brics in Africa: Collaboration for Inclusive Growth and Shared Prosperity in the Fourth Industrial Revolution".

"The Summit is focused on the need to strengthen the relationship between BRICS and Africa. In this regard BRICS leaders will also interact with African leaders on how best to bring about inclusive growth and shared prosperity through heightened collaboration," the presidency said.

"In this context, leaders of the Republics of Namibia, Gabon, Angola, Senegal, Uganda, Togo and Rwanda will participate in the BRICS-Africa Outreach session."

The Brics leaders are expected to attend the Brics Business Forum on Wednesday, followed by a welcome dinner to be hosted by Ramaphosa.

Ramaphosa will chair two meetings of Brics leaders on Thursday. The Summit ends on Friday.

"The last day of the Summit will see President Ramaphosa chairing the BRICS Outreach programme with African leaders in attendance. The President will also chair the BRICS Plus interaction and engage in a number of bilateral meetings with BRICS leaders."
