Africa’s First G20 Summit: 5 key things to know

The G20 Summit has long been one of the world’s most influential gatherings, where the globe’s largest economies meet to shape financial stability, global governance, and long-term development priorities.

But the 2025 edition carries a unique weight: for the first time since the group’s creation in 1999, the summit will be held on African soil.

On November 22–23, Johannesburg will become the center of global diplomacy, marking a symbolic and strategic shift toward a more inclusive international order.

Below are five key things to know as this meeting will be held an African soil.

1. A Historic first for Africa

South Africa’s presidency of the G20 in 2025 ushers in a landmark moment as the continent hosts the summit for the first time.

The G20, made up of 19 countries plus the European Union and the African Union represents 85% of global GDP and two-thirds of the world’s population

South Africa remains the only African nation in the grouping, but the AU’s admission as a permanent member in 2023 strengthened Africa’s representation and influence in global economic decision-making.

The Johannesburg summit therefore symbolizes more than just a rotating presidency it reflects Africa’s growing role in shaping global policy.

2. Built on the Theme of “Solidarity, Equality, Sustainability”

South Africa has chosen a theme aimed at confronting some of the world’s most pressing challenges. Pretoria’s priorities include:

• Strengthening global disaster-risk resilience
• Addressing debt distress in developing economies
• Mobilizing finance for a just energy transition
• Harnessing critical minerals for shared and sustainable growth

To deepen the summit’s focus on inequality, the government commissioned a global study led by Nobel laureate Joseph Stiglitz.

The report warns of a widening “inequality emergency,” with 2.3 billion people experiencing hunger, and urges the formation of an intergovernmental panel dedicated to reducing global disparities.

3. U.S. Boycott highlights rising diplomatic tensions

One of the most controversial developments ahead of the summit is the decision by U.S. President Donald Trump to boycott the event entirely.

Trump announced that no American official would attend, dismissing South Africa’s presidency as “a total disgrace.”

Since returning to office, Trump has taken an increasingly adversarial stance toward Pretoria, imposing 30% tariffs, the steepest in Sub-Saharan Africa, while also pushing debunked narratives about “white genocide.”

While diplomatic analysts fear the boycott could weaken multilateral discussions, South African officials have brushed it aside, calling the U.S. decision “Washington’s loss.”

Other notable absences include:

Argentine President Javier Milei, who is sending his foreign minister

Russian President Vladimir Putin, continuing his pattern of skipping in-person summits

4. Johannesburg becomes the world’s diplomatic capital

All eyes turn to Johannesburg as leaders gather at the Nasrec Expo Centre, South Africa’s largest purpose-built conference venue.

Strategically located on the edge of Soweto, the venue was chosen to demonstrate the country’s commitment to post-apartheid spatial transformation.

Johannesburg, home to nearly six million residents, has drawn international attention not just for its status as Africa’s wealthiest urban center, but also for its deep infrastructure challenges.

Crumbling roads, intermittent services, and governance issues remain a concern, prompting the African Development Bank to approve a $139 million loan for critical upgrades in July.

The city’s hosting of the summit puts both its promise and its struggles on global display.

5. End of the global South Presidency cycle

South Africa’s presidency marks the end of a remarkable sequence of G20 leadership by Global South nations, including Indonesia, India, and Brazil.

Once the summit concludes, the United States will assume the next presidency.

President Trump has already indicated plans to dramatically shrink the G20’s scope, which has expanded over the years to include climate cooperation, gender issues, and social development.

He has also questioned whether South Africa “should even be in the Gs anymore,” raising concerns about the future trajectory of the forum.
