Collaboration with the UN

Although not a United Nations (UN) organisation, the OPCW has a working relationship with the UN.

For instance, if requested to do so by the UN Secretary-General, the OPCW has a mandate in accordance with paragraph 27 of Part XI of the Verification Annex of the Convention for closely cooperating with the UN, by placing its resources at the disposal of the Secretary General to conduct an investigation of alleged use of chemical weapons in a State not Party to the CWC.
