Child-sex tourism is the commercial sexual exploitation of children by people who travel from one location to another and take part in sexual acts with children and young people. Often they travel from a richer country to one that is less developed, but child-sex tourists may also be travellers within their own countries or regions. People first started to look seriously at the issue of the exploitation of children in tourism and to try and identify suitable counteractions about 30 years ago...In this paper we will look at child-sex tourism and what is being done to stop it. We will also look at what needs to be done and what is not working.
