In 1999, ILO helped lead the Worst Forms Convention 182 (C182), which has so far been signed upon and domestically ratified by 151 countries including the United States. This international law prohibits worst forms of child labour, defined as all forms of slavery and slavery-like practices, such as child trafficking, debt bondage, and forced labour, including forced recruitment of children into armed conflict. The law also prohibits the use of a child for prostitution or the production of pornography, child labour in illicit activities such as drug production and trafficking; and in hazardous work. Both the Worst Forms Convention (C182) and the Minimum Age Convention (C138) are examples of international labour standards implemented through the ILO that deal with child labour.
