The Recommended Principles and Guidelines have been developed in order to provide practical, rights-based policy guidance on the prevention of trafficking and the protection of victims of trafficking. The Commentary on the Recommended Principles and Guidelines on Human Rights and Human Trafficking aims at providing further concrete guidance on the prevention of human trafficking and the protection of victims of trafficking. States, the international human rights system, intergovernmental agencies, civil society groups and all others involved in preventing trafficking, are encouraged to make use of the Principles and Guidelines, as well as the Commentary, in their own efforts to prevent trafficking and to protect the rights of trafficked persons.
