In a move that had been widely expected by the polls, Democratic Party candidate Moon Jae-in has won the presidency of South Korea today, following a special by-election which related the impeached Park Geun-hye. Moon had previously run for president in 2012, but narrowly lost to Park, who is now facing serious charges of bribery and abuse of power.

Moon is a major departure from the recent string of hawks in the South Korean presidency, advocating peaceful reunification with North Korea and promising to visit the reclusive nation at the first opportunity after the election. He is seen as keen to return to the Sunshine Policy of the early 2000s, aimed at improving bilateral ties and trying to avoid war.

That's not likely to sit well with the Trump Administration, which has repeatedly panned diplomacy in general as a "failed" tactic and has been talking up increasingly confrontational policies toward North Korea.
