President Donald Trump said he would block South Africa from participating in next year’s Group of 20 summit in the Miami area and cut off U.S. payments and subsidies to the country, escalating a dispute that started at this year’s G20 gathering in Johannesburg.

Trump made the announcement in a social media post, saying South Africa had refused to hand over G20 hosting responsibilities to a senior representative of the U.S. Embassy when the summit ended. He said the country would not receive an invitation to the 2026 summit, which he plans to host at his golf club in Doral, Florida.

The move is tied to a broader pattern of criticism Trump has aimed at South Africa since returning to office. The evidence packet says he skipped this year’s Johannesburg summit and repeated claims that white Afrikaners were being violently persecuted and had land seized, claims South Africa and others, including some Afrikaners, have rejected as baseless or misleading.

The dispute over the symbolic handover became part of the argument. South Africa said it was an insult to hand over the G20 presidency to what it described as a junior official, while the U.S. wanted an embassy representative to receive the gavel. That breakdown left the transition unresolved in a way that Trump framed as an affront worthy of retaliation.

The G20 context matters because South Africa hosted the first Africa-based summit and the declaration from that meeting gave more attention to development issues. The U.S. did not sign the declaration, and the Trump administration objected to the agenda, especially the climate-related parts, according to the supplied report.

Trump’s latest move also overlaps with refugee policy. The packet says his administration recently capped annual refugee admissions at 7,500, with most slots reserved for white South Africans, and had already welcomed a small group of white South Africans earlier in the year.

The evidence shows the issue is no longer just diplomatic rhetoric. By saying he will stop payments and subsidies, Trump is turning the dispute into a concrete policy threat. The packet does not specify which payments he means, but the announcement signals that Washington and Pretoria are now in open confrontation.

For South Africa, the immediate question is how to respond to exclusion from a forum where it has a standing seat. For the U.S., the decision suggests the 2026 summit could become as much about bilateral conflict as multilateral cooperation.

The only certainty from the packet is that next year’s G20, instead of serving as a routine handoff, is already shaping up as a political fight.
