Organisation for the Prohibition of Chemical Weapons (OPCW)
The OPCW implements the Chemical Weapons Convention and holds its Conference of the States Parties in The Hague every year. The Conference provides simultaneous interpretation into six official languages at plenary meetings, and its own page notes that rooms for bilateral and regional group meetings come without interpretation facilities, so delegations arrange language support for those talks separately.
