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 Trump administration says a land expropriation law South Africa recently passed was “blatantly” discriminatory against its white Afrikaners, who are descendants of Dutch and other European colonials. The Trump administration said the South African government was allowing violent attacks against Afrikaner farming communities.

It also accused South Africa of supporting “bad actors” in the world, including the militant Palestinian group Hamas, Russia and Iran.
