South Africa hosts G20 as tensions with U.S. flare amid American boycott

South Africa is preparing to host world leaders for this year’s G20 Summit in Johannesburg, but the gathering will be marked by the conspicuous absence of one of its most powerful members: the United States. The Trump administration has confirmed it will boycott the summit, escalating diplomatic tensions between Washington and Pretoria at a moment when global cooperation is already under strain.
The U.S. withdrawal stems from long-running grievances the administration has voiced about South Africa’s domestic policies grievances widely dismissed by international observers as unfounded. President Trump has repeatedly accused the South African government of confiscating white-owned land and permitting the killing of white farmers, claims that have been disproven by independent investigations but continue to circulate in far-right media. The White House has also characterised the summit’s DEI (diversity, equity and inclusion) commitments as “ideological overreach.”
For South Africa, hosting the G20 is a rare moment in the global spotlight. Banners of participating leaders line major Johannesburg highways, and President Cyril Ramaphosa has emphasised the importance of showcasing African perspectives within global economic debates. The absence of the United States the world’s largest economy casts a shadow over the event, but South African officials say preparations remain on track and that the boycott will not derail substantive discussions.
Diplomats and analysts warn the U.S. snub could deepen the rift between Washington and Pretoria, which has grown more visible since Trump returned to office. The administration’s criticisms have frustrated South African leaders, who say the accusations misrepresent the country’s policies and ignore its legal and constitutional frameworks governing land reform.
Other G20 members, meanwhile, are expected to continue engaging on issues such as climate finance, global debt reform, trade security and technology governance. For many participating nations, South Africa’s leadership offers an opportunity to elevate African priorities in global decision-making, particularly amid economic challenges and the impacts of extreme weather events.
Still, the U.S. absence may complicate efforts to reach consensus on key agenda items. The G20 has always relied on the presence of major economic powers to shape coordinated responses to global crises — from pandemic recovery plans to economic stabilisation measures. With the United States sitting out, some observers say the summit may produce fewer joint commitments than in previous years.
South African officials have responded cautiously, avoiding direct criticism of Washington while reaffirming that the summit will proceed as an inclusive forum focused on cooperation. Civil society groups and political commentators across the continent have expressed disappointment at the U.S. decision, viewing it as a missed opportunity for engagement at a time when Africa’s role in the global economy is expanding.
Despite the diplomatic turbulence, Johannesburg is bracing for intense activity as leaders from Europe, Asia, Latin America and Africa gather for a weekend of speeches, bilateral meetings and negotiations. Whether the G20 can maintain momentum without the participation of the United States and how the boycott will affect future U.S. Africa relations remains an open question.
