Article 11 deals with border measures:
• Without prejudice to international commitments in relation to the free movement of people, State
Parties shall strengthen, to the extent possible, such border controls as may be necessary to
prevent and detect trafficking in persons.
This paragraph calls for a careful balance between freedom of movement and border controls.
While States strengthen border control measures to get at traffickers and illegal migrants, it should not
happen at the expense of victims’ human rights. Training of officials will be crucial in reaching this
balance.
Article 11 furthemore requires States to adopt measures to prevent transport operated by
commercial carriers. States shall also oblige such commercial carriers or companies to ascertain that
all passengers have necessary travel documents and provide for sanctions in case of violations of this
obligation. These sanctions could include, for example that the commercial carrier is obliged to return
any persons who are found to possess inadequate travel documents.
States can also permit the denial of entry or revocation of visas of persons who are known to engage
or suspected of engaging in trafficking crimes. Finally, States shall consider strengthening co-operation
among border control agencies by establishing and maintaining direct channels of communication
