Our correspondent Jack Barton talked to Daniel Pinkston, lecturer in international relations at Troy University in the US state of Alabama. Here's his take on whether South Korean President Moon can go it alone in resolving the peninsula's problems.

JACK BARTON CGTN CORRESPONDENT "President Moon Jae-in has been talking more and more Korea need to take a leading role, including when it comes to denuclearisation and the diplomacy surrounding that. But how possible is that without really keeping the United States on board?'

DANIEL PINKSTON, LECTURER INTERNATIONAL RELATIONS, TROY UNIVERSITY, ALABAMA 'Well, it certainly is a dilemma for President Moon. He is in a very difficult position. The fact is that the problems on the Korean Peninsula national vision, the challenges posed by North Korea or classical international relations problems, no single actor can resolve them alone. It requires cooperation and multinational cooperation. So while President Moon and Korean see greater control on greater autonomy in resolving the problem which is completely understandable. If President Moon neglects the multinational component, then of course he'll undermine any solution. So he should walk the fine line."
