Mongolia and the Ban Treaty

(TPNW) on 10 December 2021, becoming the 57th state party to do so. In a
speech to the national parliament in October, the Mongolian foreign
minister, Battsetseg Batmunkh, said that joining this landmark treaty would
“meet the fundamental interests of national security”. With Russia
located to its north and China to its south, Mongolia is surrounded by
nuclear-armed states and has long emphasised the need for greater action on
disarmament. In 1992, it formally declared itself a single-state
nuclear-weapon-free zone.
