Règles matérielles du commerce international et droit économique

Substantive rules of international trade have emerged and developed especially in connection with international business transactions. Directly applicable to international business transactions, those norms have, over time, to a certain extent, supplemented the ?traditional? conflict rule of private international law. Substantive rules regulating international trade have progressively emerged in the international legal landscape responding to the need of the business community to conduct efficient business transactions. In areas such as international sale of goods, international transportation, international financial services, international investment and the space industry, we have witnessed an increased development of such substantive international rules and principles directly applicable in each sector. Those rules share the same goal : economically optimizing international business transactions. This contribution analyzes how substantive rules have emerged in different sectors of international trade responding to the need of the business community to conduct efficient international business transactions.
