South African products exported to the US will face a 30% tariff from 7 August, President Donald Trump has announced.

South Africa is the only country from sub-Saharan Africa singled out in the announcement, reflecting his strained relationship with Cyril Ramaphosa's government.

Other southern African nations, including Lesotho and Zimbabwe, have been hit with a 15% tariff, which will also come into effect in seven days.

The decision is a huge blow to South Africa, as the US is its second-biggest trading partner.

South Africa's automobile, farming and textile sectors had enjoyed duty-free access to the US market under the African Growth and Opportunity Act (Agoa).
