The possibilities and limitations in internationalising the economy of the Randstad are considered, taking into account criteria of sustainability. The Randstad has a central position in the West European urban core region. National physical planning policies are strongly focused on the Randstad. A number of strategic projects are being developed to promote the attractiveness of the Randstad. At the same time, initiatives have been taken to strengthen the administrative cohesion within the Randstad. We show that the coordination between different strategic projects is weak and that priorities are unclear. A strategic plan for the Randstad is presented, aimed at a strengthening of its international position and its environmental qualities.
