The White House said Tuesday that South Korea has made "no progress" toward honoring its bilateral trade deal with the U.S., despite U.S. President Donald Trump lowering tariffs on the country. 

A White House spokesperson told KBS on Tuesday that the simple reality is that South Korea reached a deal with the Trump administration to secure lower tariffs. 

The spokesperson said that, though Washington had lowered the levies, Seoul had made "no progress" on its end of the bargain.

The spokesperson did not specify when Trump's threatened tariff increase would take effect.

On Truth Social on Monday, Trump said that because Seoul was not honoring its agreement with Washington, he would raise tariffs on all goods from South Korea from 15 percent to 25 percent.
