U.S. President Donald Trump says Seoul and Washington have agreed to keep their trade agreement unchanged, as a problem was settled at the summit with President Lee Jae Myung.

Trump made the remarks Tuesday during a Cabinet meeting while mentioning a series of trade deals the U.S. has concluded with its trading partners.

The U.S. president said he heard there was a “problem” with South Korea, which wanted to see if it could do something, but that he met with President Lee on Monday and the two sides kept the same deal.

Trump said South Korea honored the deal, “which was nice.”

He did not elaborate on the nature of the problem.
