South Africa hosts its first G20 summit, marked by significant tensions stemming from the U.S. boycott, notably after former President Trump decided not to attend. Leaders from around the world gather with an ambitious agenda despite the absence of U.S. representation, although a last-minute attempt by the U.S. to reverse its boycott sparked controversy. South African President Ramaphosa faces scrutiny amidst diplomatic disputes, insisting that the U.S. has expressed a change of mind regarding its participation, a claim the White House has denied. As global leaders strive for agreement, the summit underscores broader issues facing Africa and the international community, including climate challenges and economic disparities.
