G20 Troika
In G20 practice, the troika comprises the previous, current and incoming presidencies, which cooperate to support continuity across the annual presidency cycle.
The word troika is used in other diplomatic contexts too; this entry refers specifically to the G20 presidency mechanism.
It gives the changing presidency a small continuity structure for planning, agenda-setting and institutional memory.
During Brazil’s 2024 presidency, the G20 troika comprised India, Brazil and South Africa. The members change with the presidency cycle.
Avoid presenting the listed historical troika as the current troika.

- Multilateral Diplomacy
Multilateral diplomacy is diplomatic engagement involving three or more states, usually through international organizations, conferences, coalitions, treaty processes, or other structured forums. It enables participants to negotiate shared rules, coordinate action, manage collective problems, and build legitimacy around outcomes that no single bilateral relationship can produce alone.
