The article presents the development strategy that was introduced in the late 1990s by the conurbations in Lorraine near the French Luxembourgian border. These cities, developing during the heyday of the mining and steel industries, had to face difficult economic and social situations in the years after the economic miracle. They found new paths for development thanks to the regional policy of the EU, which was targeted at cross-border cooperation. The presented research work dealt with the contribution of this new strategy to improve the living situation of the people near the borders and their development perspectives.
