Cypriot Foreign Minister Marcos Kyprianou has stressed the challenges and problems of mass immigration flows and their impact on the social-economic structure of the southern countries of the European Union. Speaking at the Croatia Summit 2011 wrapped up in Dubrovnik Saturday, the Cypriot FM said it was imperative to help the population in North Africa so that democratisation was not a cause of instability. He said one should not allow extremists to use the process of democratisation, and that it would be disastrous if the people there started thinking that it was better before. The European Union has to help the nations in North Africa create a political and economic infrastructure, for which investments are important, said Kyprianou.
