Mongolia

Nuclear-weapon-free state

Has not yet joined TPNW

Summary

Mongolia has not yet signed or ratified the Treaty on the Prohibition of Nuclear Weapons. However, it participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.

 

Signature and ratification

The government of Mongolia announced in October 2019 that it “is planning to accede to the [treaty] in the near future”.


In an address to the United Nations in September 2017, the then-minister for foreign affairs of Mongolia, Tsend Munkh-Orgil, welcomed the adoption of the treaty, noting that “[c]urrent tensions have only deepened the concern associated with nuclear weapons”.

 

Universalisation

Mongolia has promoted universal adherence to the treaty, including by co-sponsoring an annual UN General Assembly resolution that calls upon all states to sign, ratify, or accede to the treaty “at the earliest possible date”.

 

Negotiations

In its opening statement to the negotiating conference for the treaty in 2017, Mongolia expressed hope that the treaty-making process would “establish a strong, robust but effective legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

 

Pre-negotiations

In 2016, Mongolia voted in favour of the UN General Assembly resolution that established the formal mandate for states to commence the negotiations in 2017 on “a legally binding instrument to prohibit nuclear weapons, leading towards their total elimination”.

Mongolia was among 127 states that endorsed a “humanitarian pledge” in 2015–16 to cooperate “in efforts to stigmatise, prohibit, and eliminate nuclear weapons”. The pledge was instrumental in building momentum and support for convening the negotiations.

 

Other information

In 1992, Mongolia declared itself a single-state nuclear-weapon-free zone.
