The leaders of North and South Korea agreed in a historic summit on Friday to rid their peninsula of nuclear weapons but failed to provide any new specific measures how to achieve that. A joint statement issued after the talks between North Korean leader Kim Jong Un and South Korean President Moon Jae-in said the two Koreas confirmed their goal of achieving "a nuclear-free Korean Peninsula through complete denuclearization." North Korea has placed its nukes up for negotiations. It has previously used the term "denuclearization" to say it can disarm only when the United States withdraws its 28,500 troops in South Korea. The statement didnt say what other specific disarmament steps North Korea would take after its leader crossed over to the southern side of the worlds most heavily armed border. The two leaders talked privately for more than 20 minutes, sitting on chairs at a blue bridge inside the border truce village of Panmunjom where Moon hosted Kim for the summit. They agreed to open a permanent communication office in the North Korean town of Kaesong and resume temporary reunions between relatives separated by the 1950-53 Korean War. Kim and Moon Jae-in said that the Koreas will seek to expand civilian exchanges and pursue joint sports and cultural events. The family reunions are expected to take place around Aug. 15, an anniversary for both Koreas celebrating their peninsulas liberation from Japanese colonial rule after the end of World War II. The Koreas plan to hold high-level talks and other negotiations to fulfill the agreements made at the summit. They also said they will jointly push for talks with the United State and also potentially China to officially end the Korean War. Earlier, the two leaders poured a mixture of soil and water from both countries onto a pine tree they planted at the truce village as a symbol of peace. Kim and Moon also unveiled a stone plaque placed next to the tree that was engraved with a message saying "Peace and Prosperity Are Planted.” The meeting between Moon and Kim was just the third summit between the rivals since the Korean War. It also marked the first time that a North Korean leader crossed into the South since the signing of the war armistice in 1953.
