"We will closely consult with the United States in the process of South-North Korea dialogue and we are confident that South-North Korea dialogue helps create an atmosphere for dialogue between the USA and North Korea on resolving the North Korean nuclear issue", Moon was quoted as saying, Yonhap reported.
US President Donald Trump has said that he saw "a lot of good energy" from the inter-Korean talks that happened for the first time ever on Tuesday after a gap of two years. Technically, South Korea and the United States remain at war with North Korea after the Korean War ended in 1953 with an armistice instead of a peace treaty. "War must not break out on the Korean Peninsula again".
Speaking at the White House, Trump shrugged off reports in the press suggesting his administration was considering punitive air strikes against North Korea to show it is serious about curbing Pyongyang's development of nuclear and missile capabilities.
Trump told Moon he's open to US talks with North Korea "at the appropriate time, under the right circumstances", according to a White House description of their call.
The two nations discussed the upcoming Winter Olympics in South Korea and reached an agreement in which North Korea said it would send a delegation. Pence will stop in Alaska to review intercontinental ballistic missile defense systems and in Japan, stressing the USA commitment to stability in the region.
But U.S. Secretary of State Rex Tillerson, who will co-host the Vancouver meeting with Canadian Foreign Minister Chrystia Freeland, has been pushing for the interception of North Korean vessels. "War rehearsal and dialogue can not go hand in hand", it said in a statement, as quoted by Yonhap news agency. "China's been helping us a lot, so you can veer a little bit differently, but for the most part everything I have said I have done", he said in response to a question on his electoral promise of being tough on China.
But Mr Moon said a two-track approach of engagement with pressure would bring about a virtuous circle.
However, Kim's speech also made an offer of high-level dialogue, to which Seoul responded. The meeting "will take a series of essential decisions", including the number and names of North Korean athletes to participate in PyeongChang, and also issues related to flags, anthems, ceremonies and uniforms.
China has not done enough on the issue of North Korea for the US, President Donald Trump has said but appreciated the "great chemistry" he shares with Chinese President Xi Jinping.
The U.S. and South Korea recently postponed military exercises around the Korean Peninsula until after the 2018 Winter Olympics in the South. Trump, who acknowledged that Pyongyang may be attempting to separate Seoul and Washington, encouraged North Korea to join the games. Trump told reporters. Trump said that the phone call with Moon went well. The two nations have remained in a state of war and without diplomatic relations since the Korean War ended in 1953 without a peace treaty. He hoped that that the first North-South Korea talks since 2015 might lead to success for the world.
