The Loi de Blocage, or French Blocking Statute (Law No. 68-678 of 1968), is a French law that prohibits French individuals and companies from sharing sensitive economic, commercial, industrial, or technical information with foreign authorities outside official French legal procedures. Its main purpose is to protect French sovereignty and prevent foreign governments from obtaining information that could harm national interests or economic competitiveness. Violations of the Loi de Blocage can lead to criminal penalties. The law is often cited in cross-border legal disputes, particularly when foreign courts request data from French entities, creating potential conflicts between French law and foreign legal demands.
