The programme of the meetings will be published daily in the Conference Journal. Unless otherwise decided by the Conference. A daily programme of meetings, events and announcements will be available at the Registration Desk and at the Documentation Counter (Asia Room, World Forum).

Organisation of the Fourth Special Session of the Conference

The main business of the Special Session will be conducted in the plenary meetings and, if required, in meetings of the Committee of the Whole in the King Willem-Alexander Theatre. The Provisional Agenda of the session and Tentative Programme of Work will be made available to delegations in advance of the session.

Two separate rooms, without interpretation facilities, will be available for bilateral meetings and meetings of the various regional groups.

Regional coordinators and delegations wishing to reserve a meeting room are requested to contact Conference Services indicating the preferred date and time. These meetings will be listed in the Conference Journal.

Seating Arrangements

The seating arrangement will be clearly posted outside the King Willem-Alexander Theatre during the session. Four designated seats, two of which will be at a table, will be provided to the delegation of each State Party.

Only the nameplates of the States Parties that have registered within the 18 June 2018 deadline will be placed according to the formal seating plan. States Parties that register after this deadline will be placed in the back rows.


Simultaneous interpretation into the six official languages of the OPCW (Arabic, Chinese, English, French, Russian and Spanish) will be provided at plenary meetings and meetings of the Committee of the Whole only.

Delegations may deliver statements in a language other than an official language of the OPCW. In such cases, the delegations concerned will be required to provide interpretation into one of the six official languages, and to give advance notice to Mr Mechislav Remishevski, Head of the Language Services Branch, for required technical arrangements.


Requests for inscription on the list of speakers can be made through this form indicating the preferred date and time.

Speakers will be inscribed on the list on a first-come, first-served basis. Given the large number of delegations wishing to take the floor, a time limit of 10 minutes for collective statements, 7 minutes for national statements and 5 minutes for all other statements should be observed.

To facilitate the interpretation of statements to be delivered during the debate, delegations should provide 12 copies of each such statement to Ms Bibby Stoyanova, Documentation Counter Assistant, well in advance of delivery, or 300 copies of any statement they also wish to be distributed to other delegations.
