The transition of Central and Southern Eastern Europe countries towards a market economy, combined with the freedom of movement of people/goods has pushed young people on the roads towards Western Europe. However, these young migrants are at-risk of being trafficked. Upon arrival in another EU country, they have no guarantee of being protected by the national protection systems, more focused on (third-country) nationals and often excluding migrants from the EU. This analysis presents the Mario II project aiming at raising awareness of policy-makers on the difficulties faced by these young migrants and formulating recommendations for improvements.
