The author examines the idea of creating the International Trade Organization (ITO) in 1948 and the charter of this organization (the Havana Charter). In this document, we are interested in the role assigned to labour conditions in the regulation of international trade in the post-war vision of this process. The ITO Charter was signed by 53 countries, but the organization was never established due to the lack of ratification by the United States. Nevertheless, the study of this charter is of significant interest to determine that labour standards were meant to play a role in regulating trade and in addressing international trade disputes arising from violations of fair labour condition norms (Article 7 of the Havana Charter). This conclusion is important for understanding that the modern system of free trade, which deliberately distances itself from ILO norms, represents a deviation from the intended development path. Moreover, it is argued that the efforts of developed countries to include references to labour conditions in trade regulation, which could not be realized within the GATT and WTO frameworks, have "migrated" into specific norms of free trade agreements and the Generalized system of preferences programs (GSP).
