U.S. President Donald Trump sits during a meeting with Moon Jae-in, South Korea's president, not pictured, in the Oval Office of the White House in Washington, D.C., U.S., on Friday, June 30, 2017. Trump wants South Korea to reduce barriers to U.S. auto exports to the country and is concerned by the "enormous" amount of surplus steel the U.S. imports from the country, especially shipments that come via China, a White House administration official said this week.
