Korea watchers want to know, as the American leader spends an hour and a half on the phone with the Chinese party boss, Xi Jinping.

(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.

The debilitating political vacuum that has reigned in Seoul since South Korean President Yoon Suk-yeol’s impeachment on December 14 has finally ended. On June 3, Lee Jae-myung won South Korea’s presidential election by a decisive margin.
