Building a cross-border territorial strategy between four countries: wishful thinking?

Since 2010 and the launch of the METROBORDER project, funded by ESPON, Luxembourg and the neighbouring regions in Belgium, France and Germany have pursued the objective of creating a cross-border polycentric metropolitan region. In order to achieve this goal, the political actors have decided to elaborate a crossborderterritorial strategy to bring more coherence and cohesion to a cross-border region characterized by its strong functional integration, due to the very high number of cross-border commuters. This paper reflects the approach that we have followed, as external advisors, to animate the debate between the stakeholders and to provide evidence for the decision-making process. Its objective is to examine the content of this cross-border territorial strategy and to question whether such a strategybetween four countries is at all possible, efficient and able to answer to challenges of cross-border integration. An analytical framework has been designed, taking into consideration different approaches of cross-border integration, in order to examine, in a critical way, the content of the cross-border strategy.
