U.S. President Donald Trump followed through on his promise to punish South Africa by signing an executive order Friday stopping all aid to the country over what he called a human rights violation against a white minority group.

The president ordered that all foreign assistance to South Africa be halted and said his administration would prioritize the resettling of white, “Afrikaner refugees” into the United States.

South Africa expressed concern over a US executive order to cut financial assistance to the country, the Department of International Relations and Cooperation (DIRCO) said.
