The second biggest party in South Africa's ruling coalition thinks the 30% tariff Donald Trump imposed on its exports to the U.S. will stay unless the government changes some domestic race policies such as affirmative action,

South African President Cyril Ramaphosa and US President Donald Trump held a phone call Wednesday, a day before Washington’s 30% tariffs on the nation’s goods entering the US kicked in.

South Africa faces the highest rate in sub-Saharan Africa, reflecting Trump's strained relationship with the government of President Cyril Ramaphosa. Other African nations, including Nigeria, Ghana, Lesotho and Zimbabwe have been hit with a 15% tariff, which will also come into effect in seven days.
