In May 2010, all state parties to the Treaty on the Non-Proliferation of nuclear weapons committed themselves to "achieve the peace and security of a world without nuclear weapons".
The resolution was initiated by Kazakhstan to commemorate the closure of the Semipalatinsk Nuclear Test Site on August 29, 1991.
The International Day for the Total Elimination of nuclear weapons was observed for the first time in September 2014.
The international instrument to put an end to all forms of nuclear testing is the 1996 Comprehensive Nuclear-Test-Ban Treaty (CTBT).
