The European Commission has recently started to expand on disembarkation and controlled centre concepts. Furthermore, the EC took a step towards a first outline of the possible way to the establishment of regional disembarkation arrangements with third countries.
The disembarkation arrangements should work in parallel with the development of controlled centres in the EU: together, both concepts should surely help to ensure a truly shared regional responsibility in responding to complex migration challenges.
Specifically, concerning the “controlled centres”, the most important aim is to improve the orderly and effective processing of those disembarked in the European Union. In this field, the first step should be to separate between individuals in need of international protection, and irregular migrants with no right to remain in the EU, while speeding up returns. These centres should be managed by the host Member State with the full cooperation of the EU and the European Agencies.
