This book adopts a transnational methodology to reflect on the legalisation of international economic relations. A Liber Amicorum for Professor Francis Snyder, it outlines the ways in which legal scholarship has taken his legacy further in relation to the concept of transnational law, the -law in context- method, and the evolution of sustainability law. The lens is both theoretical and practical, delving into international investment law, financial/monetary law, free trade agreements, indigenous rights, and food law, and covering case studies from EU law, WTO law, American law, Chinese law, and Indonesian law.
