France will not once again ratify the European Treaty on Minority Languages. The federation of Bilingual Alsace asked Emmanuel Macron to ratify the agreement in February. French Secretary of State for European Affairs, Laurence Boone, responded at the end of August by recalling the resolution of the French Constitutional Council. According to the resolution, the ratification of the Treaty by France would mean "the renunciation of the constitutional principles of indivisibility of the republic, equality before the law, the unity of the French people and the official use of the language".

However, Boon points out that the non-ratification of the pact does not prevent further teaching and promoting minority languages, as they are the "cultural heritage of France".
