Trump wants to impose a 25% tariff on South Korea, but it's been postponed. Will three more weeks be enough time to negotiate? Will there be another extension?

It shows that personal grudges rather than simple economics are a driving force in the U.S. leader’s use of tariffs.

U.S. President Donald Trump's latest tariff delay provided some hope to major trade partners Japan, South Korea and the European Union that deals to ease duties could still be reached, while bewildering some smaller exporters such as South Africa and leaving companies with no clarity on the path forward.
