Recent allegations by the U.S. ambassador to South Africa that the African nation gave ammunition and weapons to Russia in December 2022, amid Russia’s war on Ukraine, illustrate the complexity of U.S.-Africa relations.

Even as South Africa investigates those claims, the Biden administration is trying to strengthen ties with the African Union, a continental member organization, and 49 of Africa’s 54 countries, including South Africa, on geopolitical and commercial issues.

The only African countries the U.S. is not courting are four that were suspended from the African Union, and Eritrea, a country with which the United States doesn’t have a formal relationship.
