The EU Sanctions Architecture against Russia: Effectiveness, Limits, and Strategic Options for 2026–2030 is a comprehensive analytical report examining the European Union’s sanctions regime against Russia as a complex and evolving system of political, economic, social, legal, hybrid, and compliance measures. The publication moves beyond simplified claims about whether sanctions “work” or “do not work” and instead offers a multidimensional assessment of their real strategic effects, operational limits, and long-term policy value. Particular attention is given to the interaction between sanctions design, enforcement quality, anti-circumvention mechanisms, and Russia’s adaptive responses. The report analyses not only the immediate consequences of restrictive measures, but also their cumulative impact on state capacity, technological access, financial resilience, logistics, and international manoeuvrability. It also explores the legal durability and governance quality of the sanctions regime, including its dependence on coordination among EU institutions, Member States, and international partners. A distinctive feature of the edition is its forward-looking perspective, presenting strategic scenarios, evaluative criteria, and policy options for the period 2026–2030. The book will be especially valuable for policymakers, diplomats, researchers, legal experts, compliance professionals, and analytical centres working on European security, sanctions policy, and Russia-related studies.
