Trafficking for labour exploitation has increasingly attracted the interest of policy makers, investigators and labour inspectors in Europe. Recognising this interest, the Ministry of Foreign Affairs of the Netherlands funded the project Capacity Building for Combating Trafficking for Labour Exploitation. The project aimed at setting up a programme of training sessions on trafficking for labour exploitation and related matters, such as cross-border judicial cooperation, transnational police investigation, and European and international legal framework of combating labour exploitation. In addition to strengthening the capacity of relevant officials to handle cases of trafficking for labour exploitation, the sequence of trainings laid the foundation for improved transnational and intra-European cooperation on this issue. The project was implemented in cooperation with the OSCE Special Representative and Coordinator for Combating Trafficking in Human Beings.
