SEOUL The Inter-Korean summit began Friday morning with a historic step as North Korean leader Kim Jong Un crossed the military demarcation line that has divided Korea for over 60 years. At the end, the leaders of the communist North and Democratic South embraced prior to announcing a joint declaration committing to denuclearization and peace. "Today, Chairman Kim Jong Un and I confirmed that the realization of the nuclear-free Korean peninsula through complete denuclearization is our common goal," said President Moon Jae-in at a ceremony to announce what they are calling the Panmunjom declaration. The North Korean leader also endorsed the joint declaration as well as past inter-Korean agreements without elaborating or specifically acknowledging the agreed upon outcome to dismantle his country's threatening nuclear program. "We have decided to open this transitional phase of improvement in relations and development by thoroughly implementing the North-South Declarations and all the agreements that have already been adopted," said Kim. Kim is now the first North Korean leader to cross into South Korea. He was greeted by Moon, who waited on the South Korean side of the borderline in the village of Panmunjom, the historic site, where the Korean War armistice was signed in 1953. The two leaders smiled as they shook hands across the border. Kim then stepped over the cement boundary marker. Kim said he was, "excited to meet at this historic place" and later wondered "why it took so long" to get there. "It really has a strong emotional impact on me," said Kim about the warm welcome he received from the people of South Korea. President Moon welcomed Kim to the South and said he would like to one day visit North Korea. Laughing, the two together momentarily stepped over the border marker into the North's side of the demilitarized zone. The two leaders posed for pictures with an unsmiling Kim dressed in a communist Mao-style suit and a smiling Moon in western business attire.
