SIPRI Yearbook 2012
II. Chemical weapon arms control and disarmament
As of 31 December 2011, 188 states had ratified or acceded to the 1993 Chemical Weapons Convention (CWC), the principal international legal instrument against chemical warfare; a further two states had signed but not ratified it; and six states had neither signed nor ratified the convention.1 No state joined the convention in 2011. The activity of the Organisation for the Prohibition of Chemical Weapons (OPCW) in 2011 was, with the notable exception of the Director-General’s advisory panel report, largely process-oriented.
