U.S. President Donald Trump said the U.S. would charge a 15% tariff on imports from South Korea, one of a number of such measures announced in the run-up to his August 1 deadline to impose such levies.

World shares are mixed after U.S. stocks slipped, as doubts rose on Wall Street about whether the Federal Reserve will deliver economy-juicing cuts to interest rates by September.

The agreement comes after other American allies, like Japan, clinched their own deals, partly to moderate President Trump’s tariff threats.
