With the assistance of the Committee of the Regions and of the Eurometropole Lille-Kortrijk-Tournai, they were able to invite fifteen journalists’ members of the sections of the AEJ for two days of meetings and discussions on the topic of “cross border mobilities”. Calling at both Brussels and Lille, journalists discovered these “small Europe’s” of collaborations between close regions and communities creating a single territory. Once the physical borders disappear, there remain other invisible, legal, lawful, barriers which block the freedom of movement of the citizens. The example was given for transport networks, conceived by a national vision, not being ready for modern mobility needs with passages from one country to another. At the end of the 2-days discovery, the participating journalists decided to launch a network between professionals interested in cross border questions to exchange ideas, best practices and knowledge.
