SEOUL -- The second summit between the leaders of the U.S. and North Korea in Hanoi is just around the corner and working-level discussions are entering the final round. But whether U.S. President Donald Trump and North Korean counterpart Kim Jong Un can reach a concrete, detailed agreement remains uncertain, as each has his own agenda.
Each leader has a potentially strong hand to play to extract concessions from the other. Trump could offer to loosen sanctions, while Kim can promise progress on denuclearization. The question is whether either one is willing to take those steps.
