Seoul, Oct 16 : South Korea's chief nuclear envoy will leave for Washington on Saturday for talks with his US and Japanese counterparts after his trip to Moscow aimed at securing Russia's cooperation in bringing North Korea back to dialogue, officials said here. Noh Kyu-duk wrapped up a four-day trip to Moscow and was set to depart for Washington, as Seoul ramps up diplomacy to resume its stalled initiative for lasting peace on the Korean Peninsula, reports Yonhap News Agency. Noh and the US special representative for North Korea, Sung Kim, are expected to meet bilaterally on Monday and join a trilateral meeting with their Japanese counterpart, Takehiro Funakoshi, the following day. Noh will likely hold two-way talks with Funakoshi on Tuesday. The three held their last in-person talks in September in Tokyo. The upcoming talks will likely touch on President Moon Jae-in's recent proposal to declare a formal end to the 1950-53 Korean War, which Noh has said is the most effective among confidence-building measures with the North. They could also discuss inducements for dialogue with the North, such as humanitarian support, and the recent reactivation of inter-Korean communication lines, which has raised cautious hope for a thaw in cross-border relations. Nuclear talks between Washington and Pyongyang have remained stalled since the Hanoi summit in 2019 between then US President Donald Trump and North Korean leader Kim Jong-un that ended without a deal. /IANS
