A/HRC/10/64 page 15 trafficked persons. The Committee has identified that the increase in vulnerability to trafficking related to discrimination and violence against women can be addressed through a range of practical measures.20 65. The Convention on the Elimination of All Forms of Discrimination against Women explicitly prohibits trafficking and exploitation of the prostitution of women (art. 6). The Committee on the Elimination of Discrimination against Women has taken up the issue of demand in fuelling trafficking, and related exploitation and the need to raise public awareness of the unlawful and exploitative nature of human trafficking. The Committee expressed concern regarding the practice of conditioning the receipt of residence permits to victims’ willingness to cooperate with the authorities.21 66. The Committee against Torture has pointed out the importance of providing assistance to victims of human trafficking, on the sole basis of their need, regardless of whether they collaborate with investigators.22 67. The Convention on the Rights of the Child prohibits trafficking in children as well as sexual exploitation of children and forced or exploitative labour (art. 35). The preamble to the Optional Protocol to the Convention on the Rights of the Child on the sale of children, child prostitution and child pornography expresses grave concern at “the significant and increasing international traffic in children for the purpose of the sale of children, child prostitution and child pornography”. The Committee on the Rights of the Child has addressed the issue of demand as part of a comprehensive response to trafficking and related exploitation.23 The Committee also addressed the issue of unaccompanied and separated children noting in its general comment No. 6 that “trafficking of such a child, or ‘re-trafficking’”24 in cases where a child was already a victim of trafficking is one of many dangers faced by unaccompanied or separated children. 20 See for instance, CCPR/CO/84/SVN, para. 11, CCPR/CO/84/THA, paras. 20 and 21, CCPR/CO/82/ALB, para. 15. 21 See for instance CEDAW/C/FRA/CO/6, paras. 30 and 31, CEDAW/C/MEX/CO/6, paras. 24 and 25. 22 See for instance CAT/C/AUS/CO/3, para. 32. 23 See for instance CRC/C/KEN/CO/2, paras. 65 and 66. 24 Committee on the Rights of the Child, general comment No. 6 (2005) on the treatment of unaccompanied and separated children outside their country of origin, para. 52.
