South Africa has ratified the ILO Minimum Age Convention, 1973 (C138). This Convention requires ratifying states to pursue a national policy designed to ensure the effective abolition of child labour and to progressively raise the minimum age for admission to employment or work. South Africa also assisted in drafting the Worst Forms of Child Labour Convention, 1999 (C182), which it ratified in 2000. In terms of this convention South Africa must take time-bound measures to eliminate the worst forms of child labour (WFCL). These include forms of bonded labour, commercial sexual exploitation of children, trafficking of children, and the use of children by others in illegal activities, including drug trafficking.
