[1/4] U.S. Treasury Secretary Janet Yellen and South Africa's Finance Minister Enoch Godongwana attend media briefing ahead of bilateral talks, at the treasury offices in Pretoria, South Africa, January 26, 2023.
He said Yellen's visit was a "momentous" occasion, noting the previous visit by a U.S. Treasury secretary was in 2014.
South Africa has remained one of Moscow's most important allies on a continent divided over Russia's invasion of Ukraine on Feb. 24 last year.
The Treasury secretary, who meets with South Africa's central bank governor later on Thursday, singled out South Africa's "Just Energy Transition Partnership," which was backed in late 2021 by the United States, Britain, France, Germany and the European Union.
They pledged a combined $8.5 billion to accelerate South Africa's transition away from fossil fuels to renewable energy, but the total bill will be much higher.
