When the British government asked some African countries if they would accept deported migrants in 2021, it got a cold shoulder from all but Rwanda.

When the Trump administration came knocking with a similar request to African nations this year, the response was much different.

Ghana, Rwanda, South Sudan and Eswatini have all received U.S. deportees who are from third countries under bilateral agreements with the Trump administration. Uganda’s Ministry of Foreign Affairs said last month that it had also struck a temporary arrangement with the United States.

Each country has its own reasons for making a deal, but experts said that their willingness reflected the calculations African nations have made as they engage with an administration that appears quick to reward those who do its bidding and punish those who resist.

The administration’s readiness to multiply tariffs on African goods and impose onerous visa restrictions has also given it leverage when asking countries to take deportees, experts say.

“Countries see it as an opportunity to get on the right side of the Trump administration,” Cameron Hudson, a senior fellow in the Africa program at the Center for Strategic and International Studies in Washington, said in an interview. “The administration has made clear that this is something that it values.”
