This project is a multi-country initiative to combat the sexual exploitation of children in travel and tourism in the Mekong sub-region. This project is a continuation and expansion of the now concluded Australia-funded Project Childhood (2010-2014) that addressed the serious issue of sexual exploitation of children in travel and tourism in the aforementioned countries. Project Childhood assisted in laying a solid foundation for improvements in the following areas: (i) legislative and regulatory frameworks, (ii) knowledge and skill improvement among specialist investigators and frontline law enforcement officers by developing and testing a training package (iii) enhanced cooperation within and across borders through the establishment of the Regional Legal Research Group. UNODC now has new and innovative tools and mechanisms necessary to continue and expand the support for Member States to strengthen capacity of police, prosecutors and judges in Cambodia, Lao PDR and Viet Nam, with a particular focus on training, legal reform, and inter-agency and cross-border cooperation mechanisms on crimes against children. This will mean working on legal research with the established National Legal Research Groups and with the police technical working groups on training of law enforcement officials. This Project consists of three main outcomes: (1) stronger legislative and policy frameworks, (2) improved skills and capacity to prosecute offences, and (3) improved information exchange mechanisms between criminal justice agencies within and across borders.
