North and South Korea , the US, and China have agreed In Principle to declare a formal end to the Korean War , says The South 's President Moon Jae-In. But talks have yet to begin because of North Korea 's demands, he added. The Korean War , which lasted from 1950 to 1953, ended with an armistice and not a peace treaty. North and South Korea have technically been At War ever since - backed by China and the US respectively - and Locked In a tense relationship. In September Kim Yo-jong, the powerful sister of North Korean leader Kim Jong-un, signalled that her country could be open to talks, but Only If the US dropped what she called a " hostile policy" against them. On Monday, Mr Moon said that North Korea had set this demand as a pre-condition to discussions. " Because of that, We Are not able to sit down for a discussion or negotiation on the Declaration . . we hope The Talks will be initiated, " He Said . The South Korean leader has made engagement with The North a cornerstone of his presidency, and has previously argued that a formal Declaration to end The War would encourage The North to give up its nuclear weapons. Mr Moon , who is currently visiting Australia, was speaking at a joint Press Conference in Canberra along with Australian Prime Minister Scott Morrison .
