When it was announced in 2023 that the African Union would become a full member of the G20, I darkly joked on a podcast that the AU’s entry into the body could very well mark the moment the G20 lost its status as one of the most important global coordination forums. Mark my words, I said, soon The Economist will be like [Mean Girls voice] “Uhhh, the G20 is OVER – it’s the G17 now.” 

Well, we’ve now arrived at that punchline — and it’s both being proven and disproven.
