A/HRC/25/48 in 2009 and to Europe through the European Financial Coalition against Commercial Sexual Exploitation of Children Online in 2012.65 107. In her country visits, several interesting initiatives were brought to the attention of the Special Rapporteur. In El Salvador, the Ministry of Tourism reported on a programme to raise awareness among personnel in small- and medium-sized enterprises, such as tourism agencies, small hotels and tour operators, about the commercial sexual exploitation of children and trafficking of children. In Madagascar, telecommunication companies have supported the establishment of child helplines. 108. In coming years, efforts are likely to focus on the consolidation of the application of these instruments, expansion of private sector-led initiatives and sharing of good practices. In 2011, the Human Rights Council decided to establish a working group to promote the implementation of the Guiding Principles on Business and Human Rights (A/HRC/RES/17/4), which provides an avenue for taking stock of developments and advocating for increased corporate social responsibility, including for children. 14. International cooperation 109. The transnational nature of the sale and sexual exploitation of children, owing to the development of information technologies, trafficking networks, tourism and migration, frequently involves children being transferred from one country to another and often implicates transnational criminal networks. This calls for coordinated preventive measures across countries, particularly neighbouring countries. Consequently, it is virtually impossible to address these crimes adequately without solid networks at the regional and international levels aimed at promoting coordination and cooperation. Compliance with international standards plays an important role in ensuring a common understanding of the nature of the crimes and fostering cooperation among countries. Cooperation ranges from border control and verification of travel documents to joint efforts from law enforcement authorities and joint preventive programmes, including harmonization of legislation, sharing of information and learning from good practices. 110. Over the past few years, international cooperation to address the sale of children, child prostitution and child pornography has increased. Many countries have police attachés within their embassies who support coordination with local law enforcement authorities and help build their capacities, assist with investigations, and facilitate the sharing of information. 111. INTERPOL has developed its activities aimed at coordinating law enforcement globally to prevent and combat crimes against children. In particular, it has set up a system of “green notices” issued to provide warnings and criminal intelligence about persons who have committed criminal offences and are likely to repeat these crimes in other countries.66 112. Managed by INTERPOL and funded by the European Commission, the International Child Sexual Exploitation image database is a powerful intelligence and investigative tool. It was launched in 2001, revamped in 2009, and is regularly updated with the latest technology, which allows specialist investigators to share data with colleagues across the world. It uses sophisticated image comparison software to make connections between victims, abusers and places. Police forces in almost 40 countries are currently connected to the database and cooperate in the identification of child sexual exploitation victims and their abusers.67 65 66 67 www.europeanfinancialcoalition.eu/. www.interpol.int/en/Internet/Crime-areas/Crimes-against-children/Sex-offenders. www.interpol.int/Crime-areas/Crimes-against-children/Victim-identification. 21
