Recep Tayyip Erdoğan, Turkish President will make the latest in a string of trips to Africa this week, visiting South Africa and Zambia, as well as attending a summit of the BRICS leading emerging economies, the presidency said on July 22.

The five BRICS countries—Brazil, China, India, Russia and South Africa—seen by analysts as rising challengers to established Western economies, are holding the group’s latest summit in Johannesburg.

Turkey is not a member of BRICS, but Erdogan will attend a special session in his capacity as the current chair of the Organization of Islamic Cooperation (OIC) at the event, according the presidency. Previous reports have said Erdogan is also due to meet Russian President Vladimir Putin on the summit’s sidelines.

Russia and Turkey have been cooperating increasingly strongly, notably on the Syria crisis, and Ankara is buying Russian S-400 air defense systems in a deal that have stirred a row with Turkey’s Western allies.

The Turkish presidency described Erdogan’s participation in Johannesburg as the “first high level contact” between Turkey and BRICS. After the visit to South Africa on July 25-27, Erdogan will head to Zambia on July 28 in what the presidency said would be the first ever visit by a Turkish head of state.

Tayyip Erdogan has made expanding Turkey’s presence in both Muslim and non-Muslim Africa one of the priorities of his foreign policy. Since being elected president in 2014, he has visited 20 African countries.

Ankara aims to have a Turkish diplomatic mission in every African country and wants to play a major role in development and trade in the continent. This will be Erdogan’s first trip to Africa since he was re-elected on June 24 for a second term with enhanced powers.
