It was a strategic mistake on Washington's part to neglect Africa in recent years. This allowed rivals like China and Russia to steadily deepen their ties with the continent. During the summit, the US seized the opportunity to regain some ground. The investments promised by Washington and the support for the AU joining the G20 are significant and long-overdue steps in the right direction.
Though Washington pretends that it wants to close the growing trust gap between the US and Africa, the Biden admin. still sees Africa merely as a pawn in its strategic goal of competing with China and Russia. However, African leaders have long known that the US isn't concerned with cooperation for mutual benefit. Africa is unlikely to actually benefit from the summit in a meaningful way.
