The Organization for the Proliferation of Chemical Weapons (OPCW) was created to oversee the elimination of existing chemical weapons and monitor the chemical industry to prevent the production of additional chemical weapons. The OPCW was created in 1997 in The Hague, Netherlands, with support from the United Nations (UN).

The OPCW has 188 members states, signatories of the Chemical Weapons Convention (CWC). Nations that did not sign the CWC include Syria, Egypt, South Sudan, Somalia, Angola, and North Korea. Myanmar signed it, but it has not ratified it to date.

As of 2012, 71% of global stockpiles of chemical weapons have been destroyed, 46% of the total amount of chemical munitions have been eliminated, and 100% of the chemical plants producing chemical weapons have been decommissioned.
