Trump Cannot Unilaterally Bar South Africa from G20

Donald Trump’s threat to exclude South Africa from the 2026 G20 summit is constrained by the forum’s rules, which require agreement among all member states for any move affecting participation. A single country cannot remove another from the grouping or revoke its membership.

Although a host nation can influence invitations to specific events, South Africa remains a full G20 member and says it will continue to participate despite the dispute.
