Knowing about the United Nations Convention on Contracts for the International Sale of Goods (CISG) means to know about the law relating to international import/export contracts applicable to more than ¾ of world trade. This book provides a valuable guide to the understanding of both the fundamentals of that law and how it is interpreted in various countries, thus making it a helpful tool not only for students but also for practitioners. The 4th edition is updated throughout with many new decision citations, including decisions rendered in August 2024. This Edition also gives proper account of the interaction between the CISG and other recently amended instruments such as the ICC Incoterms (2020) and the ICC force majeure and hardship model clauses (2020).
