Yonhap News North and South Korea have restored an inter-Korean hotline cut off last year by Pyongyang amid deteriorated relations, in a move that experts called a positive step, but warned against overinterpreting its significance. South Korean President Moon Jae-in and North Korean leader Kim Jong Un have exchanged multiple letters since the third anniversary of their April 2018 summit, and have been renewing their goal of rebuilding their strained relationship, the South’s presidential office said Tuesday after communication lines were reopened. North Korea’s state-run Korea Central News Agency (KCNA) said the resumption of communications meant that “Now, the whole Korean nation desires to see the north-south relations recovered from setback and stagnation as early as possible.”
