President Cyril Ramaphosa will host his counterpart from the disputed Saharawi Arab Democratic Republic, Brahim Ghali, at the Union Buildings in Pretoria on Tuesday morning.
Ghali is on a working visit to South Africa to lobby diplomatic support against Morocco’s occupation of Western Sahara.
Pretoria wants the Moroccan government to engage in direct talks with the Sahawari leadership to resolve the four-decade-old conflict.
Like many other African Union (AU) member states, South Africa maintains that the Moroccan occupation is illegal, and that the Saharawi people must be allowed to exercise their right to self-determination.
The AU re-admitted Morocco last year, but the decision was condemned by many human rights and civil society groups. South Africa has recognised the Saharawi Republic as an independent state since 2004.
Both President Ramaphosa and Ghali will also discuss security issues in the Maghreb region which has experience the surge in rebel attacks and kidnappings of foreign nationals by militant Islamic groups.
