HANOI (Reuters) - U.S. President Donald Trump and North Korean leader Kim Jong Un on Thursday began talks on the second day of their second summit after both sides expressed hope for progress on a U.S. demand for North Korea’s complete denuclearization.

Trump and Kim met in the Vietnamese capital, Hanoi, on Wednesday for a first round of talks and a dinner, and both appeared upbeat, with Trump saying he was satisfied with the pace of negotiations despite some criticism they were not moving quickly enough.
