Dalhuisen on Transnational and Comparative Commercial, Financial and Trade Law — The Complete 9th Edition Collection
2026 has already proven to be a turbulent year for cross-border commerce. Tariff shocks, tightening trade barriers, and supply chain disruption have combined to push global growth to its slowest pace since 2008 — and, predictably, to fuel a fresh wave of transnational commercial and financial disputes. At the same time, the legal infrastructure underneath international business is itself being rewritten: England's Arbitration Act 2025 came into force last August, China's new arbitration law takes effect this March, and regulators from the EU to the Middle East are racing to keep financial services rules current with digital assets, AI-assisted dispute resolution, and a fragmenting geopolitical order.
For any lawyer, banker, or academic trying to make sense of that landscape, there is really only one place to start: Dalhuisen on Transnational and Comparative Commercial, Financial and Trade Law, now fully updated in its 9th edition. Written by Jan H. Dalhuisen — Emeritus Professor at King's College London and Chair in Transnational Financial Law at the Catholic University of Lisbon — this six-volume work remains the most complete comparative treatment of the modern lex mercatoria available anywhere, and CLNZ Books is proud to now carry the complete set.
Why this collection matters right now
Every one of the pressures reshaping global business in 2026 has a direct counterpart in this set. Tariff-driven contract disputes and force majeure questions map onto Volume 3: Transnational Contract Law. The surge in international arbitration — and the new arbitration statutes in London and Beijing — is precisely the terrain covered in Volume 2: International Arbitration. Financial institutions navigating tightening capital markets regulation will find their reference in Volume 5 and Volume 6. And the underlying question that runs through all of it — how civil law and common law systems each construct commercial obligation, property, and risk — is the subject Dalhuisen opens with in Volume 1.
