Xi told Trump that he hopes all sides exercise restraint over the issue of North Korea and that China opposes anything that runs counter to U.N. Security Council resolutions, state media said on Monday.
Xi said during a telephone call with Trump that all sides should avoid doing anything to worsen tensions, state television reported.
