President Donald Trump sent out tariff letters to U.S. trading partners on Monday as he had promised, starting with missives to Japan and South Korea before targeting Malaysia, South Africa and other countries.

The letters listed a range of tariffs. Goods entering the U.S. from Japan, South Korea, Malaysia, Kazakhstan, and Tunisia will be subject to a 25 percent levy. There will be a 30 percent levy on South African and Bosnian goods, while imports from Indonesia will be subject to a 32 percent rate.
