The Conference of the States Parties at its Tenth Session paragraph 23.3 of C-10/5, dated 11 November 2005) decided that a memorial Day of Remembrance for all Victims of Chemical Warfare would be observed on 29 April each year — the date in 1997 on which the Chemical Weapons Convention entered into force.

This commemoration will provide an opportunity to pay tribute to the victims of chemical warfare, as well as to reaffirm the commitment of the Organization for the Prohibition of Chemical Weapons (OPCW) to the elimination of the threat of chemical weapons, thereby promoting the goals of peace, security, and multilateralism.

The Third Review Conference of States Parties to the Chemical Convention held 8-19 April 2013 in the Hague, the Netherlands, adopted by consensus a political declaration that confirms the “unequivocal commitment” of the States Parties to the global chemical weapons ban, and a comprehensive review of CWC implementation since the last Review Conference in 2008 that also maps out the OPCW’s priorities for the coming five years.
