Shares of South Korean automakers Hyundai Motor and Kia Corp fell on Thursday after U.S. President Donald Trump said the U.S. will charge a 15% tariff on imports from South Korea, including autos, as part of a trade deal.

This deal would mean the duties will be lowered from the 25% that Trump had threatened in his "tariff letter" to Seoul earlier this month.

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.
