The chemical weapons convention, adopted at Geneva by the Conference on Disarmament

Background

The treaty known in short as the Chemical Weapons Convention is registered under its full title, the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction. The Secretary-General's treaty register files it under Chapter XXVI, Disarmament, and records that it was concluded at Geneva on 3 September 1992. The text came out of the Conference on Disarmament, which adopted the report containing the Convention at its 635th plenary meeting that day. The Convention entered into force on 29 April 1997 in accordance with article XXI(1) and was registered the same day under No. 33757; its text appears in the United Nations Treaty Series, volume 1975, page 45. The same entry records that the Convention was opened for signature in Paris, from 13 January to 15 January 1993, and that it then remained open for signature at United Nations Headquarters in New York until its entry into force, in accordance with article XVIII. The register's status line shows 165 signatories and 193 parties, the two counts kept separate. Later depositary notifications recorded on the same page cover corrections to the authentic texts and approved changes to the Annex on Implementation and Verification, including a change to Schedule 1 of the Annex on Chemicals.
