Kim Jong Un provided guidance for initiatives to increase cooperation between North and South Korea following a visit by his sister, Kim Yo Jong, to the Pyeongchang Winter Olympics. The specifics of these instructions were not disclosed. The United States has indicated support for continued dialogue between the two Koreas post-Olympics, potentially leading to discussions between Pyongyang and Washington. South Korean President Moon Jae-in stated that the U.S. is willing to engage in talks with North Korea, as confirmed by Moon's spokesperson during a briefing. Moon relayed this information during a conversation with Latvian President Raimonds Vējonis. US officials are calling for increased tough international sanctions in order to pressure North Korea to abandon its nuclear program. Japan's Prime Minister also emphasized the importance of maintaining maximum pressure on North Korea. North Korea's continued missile launches and nuclear tests have defied UN resolutions as it seeks to develop a nuclear-armed missile capable of reaching the US. Japanese officials are emphasizing unity between Japan, the US, and South Korea in their approach to North Korea. The US remains committed to the denuclearization of the Korean peninsula, according to a senior Japanese diplomat. A senior military official at the North-South Korea border told Reuters that the main objective is denuclearization, and the approach involves dialogue and reciprocal actions. He mentioned that if North Korea does not take concrete actions, the United States and Japan will not alter their policies. The official also noted that North Korea has reduced the intensity of its border propaganda broadcasts since the start of the Olympics on February 9. Despite still being audible, the broadcasts are now much quieter. Moon, who was offered a meeting with Kim Jong Un in Pyongyang through his sister, is advocating for a diplomatic resolution to the conflict regarding North Korea's nuclear and missile programs. Additionally, Seoul intends to move forward with plans for family reunions of those separated by the Korean War in order to continue the dialogue initiated by the North Korean delegation's visit. In the meantime, Trump has called on Russia to increase their efforts in persuading North Korea to abandon its nuclear program, according to the White House. This is part of a strategy to put more pressure on Pyongyang. The possibility of a summit between North and South Korea, the first since 2007, has been discussed after months of tension between the three nations. Despite North Korean media not mentioning the summit offer to Moon, Kim Jong Un expressed gratitude to Seoul for their hospitality towards the delegation. Moon and his government organized various meetings and meals for the delegation at the presidential Blue House and luxury hotels, with Moon personally accompanying Kim Yo Jong to Olympic events and an orchestra concert. In addition to a high-level delegation, hundreds of North Koreans, including an orchestra and cheer squad, have traveled to South Korea for the Winter Olympics. The cheerleading team will be present at the final game of the united women's ice hockey team on Wednesday, where they will face off against old rival Japan in the preliminary round.
