SEOUL/WASHINGTON - US President Donald Trump and South Korea's new president Lee Jae-myung agreed to work toward a swift tariff deal in their first phone call since Lee was elected this week, Lee's office said on Friday (June 6).

(Reuters) -South Korea has elected liberal Lee Jae-myung as president to lead the country through a tumultuous period that will require negotiating trade tariffs with the U.S. and mending the scars from his ousted predecessor's shock martial law declaration.

Lee Jae-myung was sworn in as South Korea's president on Wednesday, just hours after his victory was certified in a snap election that brought an end to months of political turmoil in the country.
