On 26-28 June 2018 Ukrainian Delegation led by Vasyl Bodnar, Deputy Minister for Foreign Affairs of Ukraine, participated in the 4^th Special Session of the Conference of the States Parties to the Chemical Weapons Convention which took place in the Hague, the Netherlands. The main aim of the Conference was to confirm the position of States-Parties on condemnation of the use of chemical weapons by anyone, be it State or non-State actors, anywhere and under any circumstances.

Deputy Minister Vasyl Bodnar in his statement during the special session, inter alia, expressed deep concern on the repeated use of chemical weapons in Syria, Iraq, Malaysia and, most recently in the United Kingdom and expressed his conviction that perpetrators must be identified and held accountable. Ukraine expressed also its support of the draft decision of the Conference prepared by the UK, which, inter alia, gives to the OPCW Technical secretariat more authority in investigation of the alleged use of chemical weapons as well as attribution of those responsible of such use.

In spite of desperate attempts of the Russian Federation and its satellites to block the negotiation process, the draft decision proposed by the United Kingdom has been adopted by the vast majority of participating States.
