Former French President Charles de Gaulle once said when talking about France's foreign cultural communication: "cultural media have the mission of the country." It can be seen that French cultural media and foreign cultural communication play an important role in undertaking the national mission. The media development of French foreign cultural communication has gone through a stage of development from organizational communication (church) to mass communication (mass media). Audiovisual media and digital media are the main media of modern French foreign cultural communication, and their coordinated development forms a new form of integration and development of traditional media and new media. Safeguarding the economic interests of the country and promoting the development of the national economy overseas is the development trend of France's foreign cultural communication in the new era. The protection and promotion of French cultural communication to its overseas cultural economy mainly take the promotion of books, education, construction of cultural brand image and formulation of regional strategies as the action methods, so as to promote the export of cultural products, the development of service trade, the innovation of national brand image and the acquisition of economic interests in different regions.
