After 1904, several instruments relating to human trafficking were introduced, when the international agreement for the suppression of the white slave trade was adopted.
In December 2000, in Palermo, Italy, the United Nations adopted a Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children, known as the Palermo Protocol.
The UN Protocol defines trafficking in persons as an international crime. It provides a basis for developing a common strategy among law enforcement, government officials and NGOs. In addition, it contributes to harmonize criminal provisions against trafficking by States, creating conditions more conducive to cross-border cooperation, investigation and prosecution.
