North Korea plans to join global efforts to implement a total ban on nuclear weapons tests, Pyongyang’s ambassador told the United Nations disarmament body on Tuesday. North Korea “will join international desires and efforts for a total ban on nuclear tests,” Han Tae-song, ambassador to the UN in Geneva, said in an address to the Conference on Disarmament, AFP reports. North Korea announced earlier that it will dismantle its northeastern Punggye-ri test site between May 23 and 25 in the presence of local and international media.
