The foreign ministers gathering in Atlanta this week represent more than a diplomatic schedule. For the communities whose livelihoods ride on trade, energy prices, and the stability of global supply chains, the question hanging over the meeting is whether the world’s leading economic forum can still function when two of its members are barely speaking.
United States Secretary of State Marco Rubio is hosting the gathering of G20 foreign ministers in Atlanta, Georgia, today and tomorrow. It is the centrepiece of the American presidency of the group, a role the United States took over from South Africa, which had hosted the leaders’ summit in Johannesburg in November of last year.
That handover carries unresolved baggage. The United States did not attend the Johannesburg summit at all. South Africa’s presidency said at the time that the US “elected not to attend the G20 Leaders’ Summit in Johannesburg out of its own volition”.
The refusal to attend was rooted in a sharper refusal: to invite South Africa back to the table. In December 2025, Rubio laid out the American position in unsparing terms. “As President Trump has rightly highlighted, the South African government’s appetite for racism and tolerance for violence against its Afrikaner citizens have become embedded as core domestic policies,” he said. He described South Africa’s G20 presidency as “an exercise in spite, division, and radical agendas that have nothing to do with economic growth”, and wrote that the country had “routinely ignored US objections to consensus communiques and statements”.
The consequence, he announced, would fall directly on South Africa’s participation. “For these reasons, President Trump and the United States will not be extending an invitation to the South African government to participate in the G20 during our presidency,” Rubio wrote.
For South Africans, the exclusion means their government has no seat in the discussions now underway in Atlanta, even though it steered the group only a year ago. For Americans, the State Department frames the stakes differently. In a statement issued on Monday, it said the United States was “returning the G20 to its core economic mission of driving growth, strengthening economic security, and delivering results for the American people”.
That economic mission, the department indicated, would extend beyond domestic concerns. It said the US would work with G20 partners to address the geopolitical crises that feed into global economic shocks, “including threats to freedom of navigation, energy and food security, and supply chains”. Each of those items maps onto daily life somewhere: shipping lanes that carry goods and fuel, harvests that determine food prices, and the manufacturing networks that keep shelves stocked and factories running.
What the Atlanta meeting will not include is South African representation, a mark of how far the rift between Washington and Pretoria has hardened since the handover of the presidency. The sequence of events traces a steady deterioration: an American absence from Johannesburg, a public denunciation of South Africa’s conduct in the role, a formal decision to withhold an invitation, and now a summit staged without the country that presided over the previous one.
The deeper question, for the ministers seated in Georgia and for the publics they represent, is whether a forum built on consensus can deliver on the priorities the United States has set for it, particularly on economic security and the shocks that ripple from geopolitical crises into ordinary households. The two days of talks in Atlanta will offer the first indication of how the American presidency intends to answer that, and whether the group’s members are prepared to follow.
