By Joyce Lee, Hyunjoo Jin and Trevor Hunnicutt SEOUL/WASHINGTON (Reuters) -U.S. 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,

The two skip, for now, discussing the question of possible U.S. troop reductions.

The new South Korean president, Lee Jae-myung, calls himself a foreign policy “pragmatist”. He says he is driven by South Korea’s national interest, rather than ideology, and has spoken of his desire to improve relations with China and North Korea.
