Amid diplomatic tensions between host South Africa and the Trump Administration, the U.S. will be represented at a meeting of foreign ministers by the acting ambassador to South Africa.

Dana Brown, charge d’affaires and acting chief of mission until the administration of President Donald Trump appoints an ambassador, will represent the US. Rubio said Feb. 6 that he wouldn’t attend because of South Africa’s land and equality polices, and attacked what he said was the G-20’s focus on diversity and climate change.

South Africa President Cyril Ramaphosa’s priority as Group of 20 president is overhauling the global institutions he sees as skewed in favour of the West. Donald Trump might just have beaten him to it — by swinging a wrecking ball at the G20.
