EXPLAINED | Who Gets a Seat at the G20? The Power Struggle Behind the Missing Photo

Foreign ministers gathering for the G20 meeting in Atlanta on October 30 lost their customary group photograph after European representatives objected to posing with Russian Foreign Minister Sergei Lavrov. The US hosts dropped the photo opportunity.

The attendance list told another story. South Africa, a member, was absent after Washington withheld an invitation. Poland, seeking membership with US backing, attended as a guest.

How can an existing member be kept away while a country seeking entry gets in? The answer involves three different things: membership, invitations and the political signals countries send by appearing together.

What exactly is the G20?

The Group of Twenty is a forum where major developed and emerging economies discuss economic cooperation. It began in 1999, following the Asian financial crisis, and expanded to meetings of national leaders during the 2008 financial crisis. Its work includes finance, trade, energy and development.

Despite its name, it now has 21 members: 19 countries, the European Union and the African Union. India, Russia and South Africa are among the country members listed by Canada and India's G20 presidency website.

It is not a league table that automatically admits or removes countries whenever their economic ranking changes. Existing membership and a country's claim to deserve a place are separate questions.

Why was the photograph such a problem?

Several governments objected to the image of appearing alongside Russia while its war against Ukraine continues. Reuters reported that opposition extended beyond European participants to Australia and Canada.

A group photograph is easy to circulate without the arguments made inside the meeting. Governments may therefore judge the public image differently from the value of attending talks. Refusing the photograph lets them signal disapproval while retaining the opportunity to challenge other governments directly.

That distinction helps explain why the meeting could proceed even when the picture could not.

Who controls the guest list?

The country holding the annually rotating presidency organises meetings, sets priorities and invites guest countries and international organisations. The G20 has no permanent secretariat or founding charter.

That gives the host considerable practical influence. It can decide which additional voices to bring into the room and which subjects to emphasise.

But inviting a guest does not establish permanent membership. Equally, withholding an invitation does not demonstrate that the group collectively expelled an existing member. Those distinctions are central to the dispute over the American presidency.

Why has Washington kept South Africa away?

US Secretary of State Marco Rubio announced the decision on December 3, 2025. He criticised South Africa's domestic policies and accused its government of undermining consensus during its own G20 presidency. He said Washington would not invite the government during the US presidency. These were the administration's stated reasons.

South African Foreign Minister Ronald Lamola rejected the accusation that his country had sabotaged consensus. In a December 4 response, he argued that no individual G20 member had the right to exclude South Africa. He defended its presidency's emphasis on Africa and developing economies.

The disagreement is, therefore, about both policy and authority. Washington has used its control over invitations; Pretoria contests its right to use that control against a fellow member. Describing South Africa as formally expelled would go beyond what these decisions establish.

Why is Poland there, then?

Washington wants a larger role for Poland. In his December statement, Rubio praised its economic development and presented it as deserving a G20 place.

Poland's guest attendance in Atlanta gave it access to the discussions. Polish Foreign Minister Radoslaw Sikorski said Washington had proposed permanent membership and Warsaw was lobbying for it. Russia opposed the move. The invitation therefore settled attendance for this gathering while leaving the membership dispute unresolved.

The useful question is whether other members agree to a lasting change. A host's endorsement alone does not show that they have.

What does India have to do with this?

India's 2023 presidency offers a concrete example of expansion through collective agreement.

At the New Delhi summit on September 9, Prime Minister Narendra Modi recalled India's proposal for permanent African Union membership. He stated that the members agreed and, with their consent, invited its chairperson to take the new permanent seat.

The African Union's place also needs distinguishing from South Africa's. The union represents a continental organisation; South Africa holds its own national membership. One seat does not erase the other.

For India, this raises a practical institutional question: how can a forum remain useful to developing economies if participation becomes dependent on the host's political relationships? India's expansion precedent makes that question especially relevant.

Can the G20 still achieve anything when governments disagree this sharply?

It can remain useful if governments find specific areas where cooperation serves their interests.

Before Atlanta, Germany's Foreign Office identified trade, energy supplies, shipping routes and supply chains as priorities. It also highlighted cooperation with countries including India, Brazil and Indonesia. Those are reasons for engagement even amid serious political disagreements.

For readers, the practical test is whether discussions produce commitments that governments implement. Agreement on a photograph says little about that by itself.

What happens next?

The next things to examine are the ministerial meeting's published outcome, the invitation arrangements for the December leaders' summit in Miami, and any collectively agreed change in membership. Rubio has confirmed Miami as the summit location.

Until then, keep three questions separate: who remains a member, who receives an invitation and who is willing to stand beside whom.
