The European Union has reinforced its commitment to combating the proliferation and deployment of chemical weapons through a decisive announcement confirming the alignment of ten countries with new chemical armaments restrictive measures. This significant development, formalised through Council Decision (CFSP) 2025/960 on May 20, 2025, represents a unified international response to the ongoing threat posed by chemical weapons development and usage.

Understanding the Chemical Weapons Restrictive Measures Framework
The chemical weapons restrictive measures were adopted by the Council on May 20, 2025, amending Decision (CFSP) 2018/1544, which originally established the EU’s legal framework for addressing chemical weapons proliferation. This comprehensive sanctions regime encompasses travel bans, asset freezes, and prohibitions on providing financial resources to designated individuals and entities involved in chemical weapons activities.
The chemical weapons restrictive measures framework operates under both the EU’s common foreign and security policy and Article 215 of the Treaty on the Functioning of the European Union, creating a thematic sanctions regime designed to counter threats posed by chemical weapons use and proliferation. The dual legal foundation ensures comprehensive enforcement across all European Union member states and participating countries.
The chemical weapons restrictive measures currently apply to twenty-five individuals and six entities, with the latest additions specifically targeting Russian Armed Forces components. These sanctions remain in force until October 16, 2026, demonstrating the European Union’s sustained commitment to addressing this critical security concern.
Countries Aligning With Chemical Weapons Restrictive Measures
Ten nations have formally aligned themselves with the chemical weapons restrictive measures: Albania, Bosnia and Herzegovina, Georgia, Iceland, Liechtenstein, Moldova (Republic of), Montenegro, North Macedonia, Norway, and Ukraine. This alignment requires these countries to ensure their national policies conform to the Council Decision, creating a broader coalition beyond the European Union’s immediate membership.
The participation of Ukraine in these chemical weapons restrictive measures holds particular significance, given that the country has been directly affected by chemical weapons usage documented by international observers. The alignment demonstrates solidarity among nations committed to upholding international law and the principles of the Chemical Weapons Convention.
Each aligning country commits to implementing the chemical weapons restrictive measures within its national legal frameworks, including enforcing travel bans on designated individuals, freezing assets of sanctioned entities, and preventing the provision of financial support to those involved in chemical weapons activities.
Latest Additions to Chemical Weapons Restrictive Measures
The May 2025 Council Decision added three Russian entities to the chemical weapons restrictive measures list: the Radiological Chemical and Biological Defence Troops, the 27th Scientific Centre, and the 33rd Central Scientific Research and Testing Institute of the Ministry of Defence of the Russian Federation. All three entities belong to the Russian Armed Forces and have been implicated in chemical weapons development and deployment.
This decision followed reports from the Organisation for the Prohibition of Chemical Weapons (OPCW) issued in November 2024 and February 2025, which confirmed the presence of riot control agents such as CS (2-Chlorobenzalmalononitrile) and related compounds in samples collected from Ukrainian frontlines. The chemical weapons restrictive measures directly address the use of these agents as methods of warfare, which violates the Chemical Weapons Convention to which Russia is a State Party.
The addition of these entities to the chemical weapons restrictive measures demonstrates the European Union’s responsiveness to verified intelligence and its commitment to holding accountable those entities involved in chemical weapons proliferation and usage.
Historical Context of Chemical Weapons Restrictive Measures
Historical Context of Chemical Weapons Restrictive MeasuresThe European Council confirmed on March 22, 2018, that the use of chemical weapons, including any toxic chemicals used as weapons under any circumstances, is completely unacceptable, must be systematically and rigorously condemned, and constitutes a security threat to all. This declaration formed the foundation for subsequent chemical weapons restrictive measures.
The Council adopted the legal framework for chemical weapons restrictive measures on October 15, 2018, establishing comprehensive measures against proliferation and use. Since its implementation, the framework has been regularly renewed and expanded to address emerging threats and incorporate new intelligence regarding chemical weapons activities.
The chemical weapons restrictive measures have been progressively strengthened, with previous sanctions targeting individuals and entities involved in various incidents, including the poisoning of Alexei Navalny with Novichok-type nerve agents and the production of chemical weapons delivery systems in Syria.
Role of International Organisations in Supporting Chemical Weapons Restrictive Measures
The European Union is the biggest contributor of voluntary funding to the Organisation for the Prohibition of Chemical Weapons activities, with EU member states’ combined yearly assessed contributions accounting for approximately 25% of the OPCW’s regular annual budget. This financial support reinforces the effectiveness of chemical weapons restrictive measures through enhanced monitoring and verification capabilities.
The OPCW’s technical expertise has been instrumental in documenting violations that trigger chemical weapons restrictive measures. The organisation’s investigation and fact-finding missions provide the evidence base necessary for the European Union to designate individuals and entities for sanctions.
The European Union and OPCW concluded a cooperation agreement in February 2024, establishing a memorandum of understanding that enhances coordination and strategic cooperation. This partnership strengthens the implementation and enforcement of chemical weapons restrictive measures globally.
Impact and Objectives of Chemical Weapons Restrictive Measures
The chemical weapons restrictive measures serve multiple strategic objectives. Primarily, they aim to deter future chemical weapons usage by imposing significant consequences on perpetrators and their supporting infrastructure. The asset freezes and travel bans create tangible obstacles for individuals and entities involved in these activities.
Additionally, the chemical weapons restrictive measures support the full implementation of the Chemical Weapons Convention by demonstrating the international community’s commitment to enforcement. The sanctions complement diplomatic efforts and reinforce global norms against chemical weapons proliferation.
The European Union continuously monitors developments related to chemical weapons, restrictive measures, and can amend the list of designated persons and entities at any time based on new intelligence. This adaptive approach ensures the sanctions remain relevant and effective in addressing evolving threats.
Conclusion
ConclusionThe alignment of ten countries with the European Union’s chemical weapons restrictive measures represents a significant milestone in international efforts to combat chemical weapons proliferation. These comprehensive sanctions, targeting specific Russian entities involved in chemical weapons development and usage, demonstrate the global community’s unified stance against these prohibited weapons. As the chemical weapons restrictive measures framework continues until October 2026, the international coalition remains vigilant in monitoring compliance and responding to emerging threats, ensuring accountability and deterrence remain at the forefront of global security efforts.
