Human trafficking is often associated with exploitation in prostitution. However, the UN Trafficking Protocol lists several other forms of exploitation as forms of human trafficking, including domestic and sexual servitude. These are forms of exploitation that can take place within the context of a marriage. In this article I discuss issues of vulnerability, power and exploitation in the context of transnational marriage. It is based on a study of Thai and Russian women married to Norwegian men conducted in 2006–2008. Based on an analysis of the experiences, priorities and challenges these women face, I argue that systematic exploitation of the dependence created in transnational marriage in some instances can and should be conceptualized and prosecuted as cases of human trafficking.
