The Netherlands Ministry of Foreign Affairs wrote in its 2005 document "Dutch Policy on Prostitution: Questions and Answers" provided on its website:

“To end abuses in the sex industry, the Netherlands decided to change the law to reflect everyday reality. It is now legal to employ prostitutes who are over the age of consent, and do the work voluntarily, but stricter measures have been introduced under criminal law to prevent exploitation.

The legalisation of brothels enables the government to exercise more control over the sex industry and counter abuses. The police conduct frequent controls of brothels and are thus in a position to pick up signs of human trafficking. This approach is in the interests of prostitutes themselves, and it facilitates action against sexual violence and abuse and human trafficking…

An important spin-off of the policy is that it prevents human trafficking, which is characterised by exploitation, coercion and violence. The lifting of the ban on brothels makes prostitution a legitimate occupation and gives prostitutes the same rights and protection as other professionals.

The labour laws offer the most effective protection against exploitation, violence and coercion. The policy is based on the conviction that strengthening the position of women is the best way to combat sexual violence. Moreover, abuses are easier to detect when prostitutes operate publicly and legally rather than in a clandestine subculture.”
