South Korea Urges North to Uphold Deals Amid Rising Animosities Associated Press SEOUL, SOUTH KOREA - South Korea on Sunday convened an emergency security meeting and urged North Korea to uphold reconciliation agreements, hours after the North threatened to demolish a liaison office and take military action against its rival. There's concern that North Korea could turn to provocation to bolster its internal unity and wrest outside concessions as nuclear talks with the United States remain deadlocked. Observers say North Korea desperately needs sanctions relief in the face of harsh U.S.-led sanctions and the coronavirus pandemic. South Korea's national security director, Chung Eui-yong, held an emergency video conference with ministers in charge of security and military generals on Sunday morning to discuss the latest situation on the Korean Peninsula and the government's possible steps, the presidential Blue House said in a statement. The Unification Ministry, which handles relations with North Korea, later said that both Koreas must strive to abide by all agreements they have reached. The Defense Ministry said separately it closely monitors North Korea's military and maintains a firm military readiness. Both ministries said the South Korean government "views the current situation as grave." On Saturday night, Kim Yo Jong, the influential sister of North Korean leader Kim Jong Un, warned that Seoul will soon witness "a tragic scene of the useless North-South liaison office (in North Korea) being completely collapsed." She also said she would leave to North Korea's military the right to take the next step of retaliation against South Korea. .
