Nuclear-weapon free state

Voted in favour of adopting TPNW

Has signed TPNW, but not yet ratified

Tanzania has signed but not yet ratified the Treaty on the Prohibition of Nuclear Weapons.

Palamagamba Kabudi, the minister for foreign affairs of Tanzania, signed the treaty at a high-level ceremony on 26 September 2019. The government of Tanzania announced in October 2019 that its domestic process for ratifying the treaty is under way.

Kabudi said that “the treaty is important, not only because it complements existing international instruments on nuclear weapons, but also because it places those weapons on the same legal footing as other weapons of mass destruction”.

Tanzania participated in the negotiation of the treaty at the United Nations in New York in 2017 and voted in favour of its adoption.

In an address to the United Nations in September 2017, Augustine Mahiga, the then-minister for foreign affairs of Tanzania, said: “Tanzania commends the recent adoption of the nuclear ban treaty, which puts nuclear weapons on the same legal ground as other weapons of mass destruction.” He added that “[w]e should all support this treaty”.

Tanzania voted in favour of a UN General Assembly resolution in 2019 that welcomed the adoption of the treaty and called upon “all states that have not yet done so to sign, ratify, accept, approve, or accede to the treaty at the earliest possible date”.

In its opening statement to the negotiating conference, Tanzania said that the use of nuclear technology “in weapon systems remains the worst nightmare to all of us” and poses “a great security risk to the entire humanity”.

In 2016, Tanzania 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”.

Tanzania 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.

Tanzania is a state party to the 1996 Treaty of Pelindaba, which established Africa as a nuclear-weapon-free zone.
