It is well understood that human trafficking is the criminal exploitation of humans in a wide range of industries and settings. In the global context, there are many signs that this crime is still increasing, not diminishing. There have been some positive developments in examining this crime and specifying anti-trafficking policies. Meanwhile, trafficking of humans in Vietnam has been the subject of increasing national attention, which can be observed in several ways, including: formulating legal initiatives, entering into bilateral agreements with other countries, ratifying and implementing various international treaties, and implementing anti-trafficking activities. In this paper, the author intends to exam the human trafficking definition under international and Vietnamese legal framework.
