United States Secretary of the Treasury Janet Yellen has reaffirmed her country’s commitment to deepening relations and trade with Africa during a visit to Senegal, amid competition across the continent from China and Russia.

“The United States is all in on Africa, and all in with Africa,” Yellen said on Friday morning at a business incubator in the Senegalese capital of Dakar, where she touted the fruits of a new “mutually beneficial” US economic strategy towards Africa.

“Our engagement is not transactional, it’s not for show, and it’s not for the short-term,” she said.

Yellen’s three-country tour of the region comes just weeks after US President Joe Biden hosted the leaders of dozens of African nations, as well as the African Union, for the second US-Africa Leaders Summit in Washington, DC.
