United Regions of Europe
A good neighborhood
Whilst the existing cooperation is still struggling with the challenges of national borders, the integration benefits from a common history and cultural similarity among the neighbours.
The next logical step should be to overcome all historical border conflicts and to form a new and truly European unity for the future.
Even language is not a problem, as Luxembourg is already bilingual and has both German and French as official languages.
… would make a strong greater Region without national borders.
A cross-border region yet in operation
The Saarlorlux cross-border project is an excellent example of a good working cooperation that is located between Luxembourg, Lorraine (France), Wallonia (Belgium), Saarland and Rhineland-Palatinate (Germany).
ESPON, a European Network for statistics writes about the cooperation within the region in it's paper about an urban agenda for Europe:
"A number of factors have created high labour mobility flows, directed from smaller neighbouring urban centres, such as Thionville, Arlon, Trier and Longwy to the core and metropolitan region of Luxembourg.
To a lesser extent commute towards Saarbrücken. Reasons for commuting are larger differentials in terms of attractive job opportunities in Luxembourg when compared to neighbouring regions." (ESPON)
