JOHANNESBURG, South Africa – The United States unexpectedly announced a $4.6 billion commitment to the Global Fund to Fight AIDS, Tuberculosis and Malaria during an event held on the sidelines of the G20 Leaders’ Summit in Johannesburg on Friday, November 21, 2025. The pledge, though a slight reduction from previous cycles, arrived in the middle of a highly publicized diplomatic rift with South Africa, the host nation, which had been sharply criticized by the US administration.

Partners around the world pledged a total of approximately US$11.34 billion to the organization, which is the largest multilateral grant funder of global health systems.
Political Context and Diplomatic Tension
The US pledge’s timing and magnitude drew considerable attention due to the backdrop of significant tension between Washington and Pretoria.
-
US Boycott of G20: The US administration, led by President Donald Trump, ordered a boycott of the G20 Summit, citing unsubstantiated claims of racial discrimination against the white Afrikaner minority in South Africa. This absence, particularly with the US scheduled to take over the G20 presidency the following year, undermined the host nation’s efforts to champion issues important to the Global South.
-
South Africa’s Stance: South African President Cyril Ramaphosa and other officials pushed ahead with the summit, presenting the country as a champion of multilateralism and focusing the agenda on increasing financing for debt-sustainability, a just energy transition, and global inequality. South Africa committed US$36.6 million to the Global Fund, a joint public-private pledge.
-
Coercion Accusations: The diplomatic dispute escalated when South Africa’s foreign ministry accused the US of attempting “coercion by absentia,” after media reported a US diplomatic note that opposed the issuance of a traditional G20 leaders‘ declaration in its absence.
The Global Fund Commitment
Despite the political turmoil, the $4.6 billion commitment by the US, the Global Fund’s largest historic donor, was seen as a vital show of support for the institution’s life-saving work.
-
Replenishment Outcome: The $11.34 billion raised by the Global Fund, while falling short of its original $14 billion target for the current three-year cycle, was hailed as a display of global solidarity amid challenging geopolitical and economic conditions.
-
Impact: The funds are critical for sustaining the fight against HIV, tuberculosis (TB), and malaria, and for deepening investment in resilient and sustainable health systems globally. The US pledge, in particular, recognized the Fund’s role in scaling innovations and supporting critical frontline healthcare workers.
-
Saving Lives: President Ramaphosa noted that the pledges represented a “defining moment for global health,” ensuring millions of lives will be saved and stronger health systems will be built, despite the broader geopolitical strains on multilateral cooperation.
The juxtaposition of the massive US commitment to a globally vital health initiative alongside the highly publicized political snub of the host country highlighted the complex and often contradictory nature of current international relations.
