The Fourth Edition of Principles of International Business Transactions provides a more comprehensive examination of the law relevant to the subject matter and detailed citations to caselaw and other supporting authorities. It can be used by courts and legal practitioners as a resource for research and analysis, as well as by students and professors as a supplement for any international business law course. It tracks the authors' popular problem-oriented coursebook, International Business Transactions, and their three spin-offs Contracting Across Borders, Trade and Economic Relations and Foreign Investment Law. Coverage moves sequentially from structuring international sales transactions to international sales law and letters of credit to regulation of international trade to transfers of technology to foreign investment to international business dispute settlement.
