South Korean president Moon Jae-in clearly won the gold medal for diplomacy at the PyeongChang games -- where athletes from both sides of the divided peninsula marched side by side under a unified flag. But can the gains made during the Games last and build into talks on denuclearization? CGTN's Jack Barton has this report from Gangneung.
Kim Jong Un's sister represented Pyongyang's soft power at the start of the Winter Games while Donald Trump's daughter was the smiling face of her father's administration at the close.
South Korea's president Moon Jae-in received an invitation to visit Pyongyang and held talks with all, as the prospect of a nuclear war quickly receded.
There was a lot of feel-good Olympic diplomacy, but how much has really changed?
CHO HAN-BUM DIRECTOR, SOUTH KOREA'S COUNCIL OF UNIFICATION POLICY "There's no change about North Korean denuclearization. Without North Korean denuclearization progress we can have no advance in the inter-Korean relationship."
There were also protests against the arrival in the south of Kim Yong Chol, a man blamed for the sinking of a South Korean navy corvette and the deaths of 46 sailors. But it was Kim who delivered the message that Pyongyang is now willing to talk with Washington.
The White House responded by saying talks were possible but only if Pyongyang agreed in advance they would be about denuclearization.
CHEONG SEONG-CHANG POLICY ADVISOR, SOUTH KOREA'S MINISTRY OF UNIFICATION "If the United States seeks more pragmatic approach towards the DPRK nuclear and missile issues then a compromise between the DPRK, the United States and the international community could be reached."
President Moon has a clear predicament. How to preserve an Olympic detente while not upsetting the South's alliance with the US.
ACK BARTON GANGNEUNG "The level of diplomatic progress has taken almost everyone by surprise, and though the Olympics was a great facilitator as Olympic Committee President Thomas Bach noted, sports has played its role, now it's time for politicians to do their bit. Jack Barton, CGTN, in Gangneung."
