US Treasury chief, Janet Yellen, holds a bilateral meeting with her South African counterpart, Enoch Godongwana, on the last stop of her African tour.

Godongwana describes the US as one of "South Africa's top trading partners" and that trade between the two countries serves as a "critical launchpad for the development of both economies."
