Slapped with a steep tariff, South African officials hope for a deal, but some worry the U.S. may insist that it roll back measures that redress the damage of apartheid.

South Africa on Monday outlined support measures for local companies that will be hit by a 30% U.S. tariff this week, including exemptions from some competition rules and financial support facilities.

South Africa is still waiting to hear back from the U.S. on a trade proposal it submitted last month in the hope of avoiding high tariffs, officials said on Monday, with only four days left before a 30% levy on its exports is due to kick in.
