Nuclear pariah North Korea is set to chair a United Nations forum on nuclear disarmament for four weeks from late May, the U.N. has announced, leading one Geneva-based advocacy group to encourage a diplomatic boycott of the event.

The U.N. Conference on Disarmament will include discussions on nuclear weapons, preventing nuclear war and transparency in armament to support “effective international arrangements to assure non-nuclear-weapon States against the use or threat of use of nuclear weapons,” according to the U.N. website.
