President Moon Jae-in spoke on the phone with U.S. President Donald Trump late Friday and discussed the PyeongChang Olympic and Paralympic Winter Games and Korean Peninsula affairs. 

Senior presidential press secretary Yoon Young-chan said Saturday that during the 30-minute conversation, the two leaders agreed to closely cooperate for the success of the Games.

Moon expressed hope that the momentum on improving inter-Korean dialogue spurred by the Olympics will continue to help build peace on the Korean Peninsula. 

He also hoped the visit to South Korea by Vice President Mike Pence who leads a U.S. delegation to the Olympics can also help this peace-building process.

Moon assessed that Trump's consistent and principle-based policies on Korean Peninsula affairs greatly contributed to fostering an atmosphere for a peaceful Olympics, including the participation of North Korea in the games.

Trump meanwhile stressed the need to ease the trade imbalance between the two nations to which Moon said that Seoul will sincerely respond to ongoing negotiations aimed at revising the bilateral free trade agreement.
