The 1993 Chemical Weapons Convention (CWC) entered into force on 29 April 1997. It ‘prohibits the development, production, acquisition, retention, stockpiling, transfer and use of chemical weapons. It requires each State Party to destroy chemical weapons and chemical weapons production facilities (CWPFs) under its jurisdiction or control, as well as any chemical weapons it abandoned on the territory of other States Parties. All
States Parties are prohibited from engaging in military preparations to use chemical weapons, from assisting or encouraging other states to engage in activities prohibited by the CWC and from using riot control agents such as tear gas “as a method of warfare”.’ (See: www.opcw.org)
As of August 2007, the treaty has 182 states parties and 6 signatory states. The Secretary-General of the United Nations is the treaty depositary; the Organisation for the Prohibition of Chemical Weapons (OPCW) is the treaty secretariat.
As noted in the Convention’s Preamble, the 1925 Geneva Protocol (prohibiting the use of chemical and biological weapons in war) and the 1972 Biological and Toxin Weapons Convention (BWC) (outlawing biological and toxin weapons and requiring their destruction) are both multilateral instruments pertinent to the CWC. See Reference:treaty/resolutions: biological weapons for documentation relevant to the Geneva Protocol and the BWC.
