South Korean President Moon Jae-in Monday welcomed Pyongyang’s announcement that it is set to dismantle its only nuclear test site. Moon said the North’s move shows how sincere the country is about making the talks between Kim Jong-un and US President Donald Trump a success. “This would be a preliminary step toward complete denuclearization,” Moon said during a meeting with his aides, AP reports. North Korea said Saturday that it will dismantle its northeastern Punggye-ri test site between May 23 and 25 in the presence of local and international media. Kim and Trump are expected to meet for June 12 talks in Singapore. Trump tweeted Saturday that North Korea’s plan to dismantle the nuclear test site is “a very smart and gracious gesture.”
