International Sanctions in 2025: Why Every Law Library Needs This Reference Now
International Sanctions in 2025: Why Every Law Library Needs This Reference Now
International sanctions have become one of the most consequential and technically demanding areas of international law. What was once a relatively specialised field — the domain of foreign policy lawyers and compliance specialists — has exploded into a discipline that touches trade law, financial regulation, criminal enforcement, human rights, and geopolitics simultaneously. The publication of the Elgar Encyclopedia of International Sanctions arrives at precisely the right moment.
Since February 2022, the pace of sanctions development has been extraordinary. The European Union alone has adopted twenty packages of restrictive measures against Russia, with the 20th package — adopted in April 2026 — introducing a total sectoral ban on cryptocurrency platforms operating in Russia and designating 58 companies linked to drone manufacturing. The UK has sanctioned over 3,200 individuals, entities and ships under its Russia regime. The US sanctioned Rosneft and Lukoil in October 2025, threatening secondary sanctions against any foreign financial institution continuing to do business with those companies. These developments affect institutions from Tokyo to Toronto, from law firms in London to compliance departments in Singapore.
And yet, the legal framework governing all of this — who can sanction, what measures are permitted, how enforcement works, what legal challenges are available — has never been assembled in a single, authoritative reference work. Until now.
What the Elgar Encyclopedia Covers
Edited by three of the world's leading experts — Clara Portela (University of Valencia), Andrea Charron (University of Manitoba) and Mirko Sossai (University Roma Tre) — this 744-page Encyclopedia brings together over 70 entries from scholars across disciplines and jurisdictions. The structure is clear and practical:
Part I: Profile of Senders — covering the African Union, Arab States, Canada, China, the EU, France, Japan, the League of Nations, Russia, Switzerland, Ukraine, the UK, the UN, the US, and the World Bank. Understanding who sends sanctions, and under what legal authority, is the foundation of the entire field.
Part II: Types of Measures — arms embargoes, banking system restrictions, commodity sanctions, financial sanctions, travel bans, and more. Each entry explains the legal architecture and enforcement mechanisms of a specific sanction type.
Part III: Sanction Episodes — case studies of specific regimes in operation, analysing how different senders have responded to particular situations and what outcomes resulted.
Part IV: Legal and Institutional Frameworks — compliance, enforcement, legal challenges, and humanitarian exemptions. This section is essential for practitioners navigating the intersection of sanctions law and due process.
The Sanctions Landscape Has Never Been More Complex
The divergence between the US and its traditional allies on Russia sanctions — a notable feature of 2025 — illustrates exactly why a reference like this matters. While the EU and UK have continued tightening sanctions targeting Russia's shadow fleet, banking sector, and energy revenues, the Trump administration has taken a markedly different posture, declining to add new broad sanctions while pursuing ceasefire diplomacy. Institutions operating internationally must now navigate not one sanctions regime but several, which may operate in tension with each other.
At the same time, enforcement is intensifying. The EU's 19th package marked the first time a law firm — Maxima Legal — was sanctioned for facilitating sanctions evasion through falsified documents. OLAF and Europol have formalised their cooperation on sanctions circumvention. In June 2025, OFAC assessed a penalty of over $215 million against a US investment firm for managing assets belonging to a sanctioned Russian oligarch. The message is clear: sanctions compliance is no longer a box-ticking exercise, and the legal consequences of getting it wrong are severe.
For legal professionals, compliance officers, academics, and policy researchers, the Elgar Encyclopedia provides the analytical framework to understand these developments — not just as news, but as law.
Why Law Libraries and Academic Institutions Should Add This Title
The Elgar Encyclopedia of International Sanctions fills a genuine gap in legal reference literature. There is no comparable work that covers the full range of senders, measure types, and institutional frameworks in a single, searchable, encyclopaedic format. It is interdisciplinary by design — drawing on international law, political science, and economics — which makes it relevant across faculties and departments.
For institutions building or updating their collections on international law, foreign policy, or compliance, this is a title that will be consulted repeatedly, not filed and forgotten. At CLNZ Books, we supply academic and professional institutions worldwide. This Encyclopedia belongs in every serious law library collection.

Q&A
Q: What is the difference between UN sanctions and autonomous sanctions imposed by the EU or US?
A: UN sanctions are adopted by the Security Council under Chapter VII of the UN Charter and are binding on all member states. Autonomous sanctions — such as those imposed by the EU, US, or UK — are unilateral measures adopted independently by individual states or blocs, without UN authorisation. They are legally binding only within the jurisdiction of the sender and on entities subject to that jurisdiction.
Q: How do international sanctions against Russia's shadow fleet work in practice?
A: Sanctions targeting Russia's shadow fleet typically involve asset freezes on listed vessels, port access bans in sanctioning states, and prohibitions on providing services — including insurance, reinsurance, and maritime transport — to those vessels. As of early 2026, the EU has designated over 340 shadow fleet vessels. Enforcement relies on cooperation between flag states, port authorities, and financial regulators.
Q: What legal remedies are available to individuals or entities listed under international sanctions?
A: Legal challenges vary by jurisdiction. In the EU, listed individuals and entities may bring annulment proceedings before the Court of Justice of the EU. In the US, challenges to OFAC designations are possible through administrative review and judicial proceedings. The effectiveness of such challenges has grown as courts have imposed stricter procedural requirements on sanctions authorities.
Q: What is sanctions circumvention and how do authorities detect it?
A: Sanctions circumvention involves actions designed to evade the legal effect of sanctions — for example, routing transactions through third-country intermediaries, using front companies, or exploiting gaps between different national regimes. Authorities detect circumvention through financial intelligence, export control monitoring, customs data, and cooperation between agencies such as OLAF, Europol, and OFAC.
Q: How do humanitarian exemptions operate within international sanctions regimes?
A: Most sanctions regimes include carve-outs or general licences permitting transactions necessary for humanitarian purposes — food, medicine, medical equipment, and basic utilities. These exemptions are subject to specific conditions and may require prior authorisation. The scope and accessibility of humanitarian exemptions vary significantly between regimes and are a subject of ongoing legal and policy debate.
