This Handbook forms part of a collection of tools and resources developed by and for the Member States of ASEAN, through the Asia Regional Project on Trafficking in Persons (ARTIP), aimed at strengthening national and regional responses to TIP. I take this opportunity to urge relevant officials of ASEAN Member States to familiarize themselves with these tools and resources, which now include a comprehensive series of training materials for criminal justice professionals including judges and prosecutors, investigators and front line law enforcement officials.
