President Donald Trump on Monday set a 25% tax on goods imported from Japan and South Korea, as well as new tariff rates on a dozen other countries.

The United States’ closest security allies in Asia, along with several Southeast Asian countries, have been given another three weeks to negotiate trade deals — or face higher tariffs.

While South Korean imports to the U.S. face 25% tariffs, the same as Trump promised in April, the rate on Japan has been raised by 1 percentage point to 25%.
