African trade flows may shift further away from the US after President Donald Trump announced a slew of new tariffs, the head of Citigroup Inc.’s regional office said.Trump unveiled a revised global plan on Thursday that imposed levies as high as 30% on imports from countries including South Africa — the continent’s biggest economy — and Algeria.

China’s top leaders have pledged to help companies slammed by higher U.S. tariffs but held back on major moves after trade talks.

South African products exported to the US will be hit by a 30% tariff from 7 August, President Donald Trump has announced. South Africa faces the highest rate in sub-Saharan Africa, reflecting Trump's strained relationship with the government of President Cyril Ramaphosa.

Apple may be the tech company most exposed to the Trump-era global tariffs, with the majority of its iPhones still manufactured in China. But the company calmed Wall Street’s concerns with its latest financial results, which showed a surge in iPhone sales. CEO Tim Cook also laid out a roadmap to ease the impact of levies.

Apple's best revenue growth in three years failed to impress, with shares down about 1% in volatile trading on Friday, as investors questioned whether a tariff-driven surge in iPhone sales would last.

Apple Inc. reported its fastest quarterly revenue growth in more than three years, easily topping Wall Street estimates, after demand picked up for the iPhone and products in China.
