A/HRC/WG.6/1/ARG/4 page 14 population. It also asked what specific measures Argentina has taken to date to prevent, investigate and punish trafficking of migrants, particularly migrant women sexually exploited and to provide assistance and support to victims. The Republic of Korea encouraged the Government to follow-up on such measures in order to ensure their effectiveness. Finally, it noted with satisfaction various efforts to recognize and fulfil the rights of indigenous populations and to ensure their participation in various aspects of society. It asked how the Government assesses those efforts today and recommended that Argentina intensify its measures to fully realize the rights of its indigenous populations, particularly their representation in the civil service and public institutions. 55. Nigeria noted with interest that Argentina is party to most international human rights instruments and particularly welcomed the ratification of the Rome Statute on the International Criminal Court and Optional Protocol to CAT. Nigeria asked how Argentina will respond to the concern of CERD about complaints regarding acts of racial discrimination, violent racist attacks and acts of police personnel committed on racial grounds. By way of recommendations, it encouraged Argentina to (i) take appropriate measures to combat racism and racist-related phenomena; (ii) ratify the Second Optional Protocol to the International Covenant on Civil and Political Rights and the Convention on the Rights of Persons with Disabilities including its optional protocol; and (iii) while welcoming the laudable initiative on the devolution of national and provincial land to indigenous communities, Nigeria encouraged the authorities to provide adequate protection to indigenous peoples to enable them to own and possess these lands. 56. Responding to questions raised on allegations of torture and ill-treatment by the security forces, Argentina indicated that it would like to make a distinction between crowd control and situations of detention. Crowd control has changed radically in Argentina. There have been social protests in Argentina and at no time have there been acts which had to be deplored, except in the case in which the victim was a policeman and another case in which the victim was a professor killed by the police of one province. With regard to the situations of detention, Argentina is aware of these abuses. However, within the framework of the fight against impunity, Argentina is starting to see very severe sentences being applied to police officers who commit these crimes. 57. Another subject that cannot be ignored is the issue of the right of indigenous peoples, mentioned by Mexico and other countries. Argentina noted that there is a delay in the implementation of the international and national framework in this regard, and indicated that it must openly recognize this. However, Argentina noted that it has made efforts in two fundamental areas, i.e. land and culture. The Emergency Act on possession and ownership has not yet resolved the matter, but it has opened a parenthesis on the important issue of the relationship between indigenous peoples and their land. At the same time, a census should be conducted, which is essential to guaranteeing the rights of indigenous peoples. In terms of culture, Argentina is opening bilingual schools, which are very important. 58. Regarding the ways in which the National Plan to Combat Discrimination was developed and progress was made, in close association with sectors of the civil society. The INADI has an Advisory Council in which NGOs and other interested persons and/or persons with expertise in the fight against discrimination are represented. In this area however, Argentina also recognized a delay in practise. For example, the autonomous City of Buenos Aires has legislation that is very complete and may be exemplary with regard to persons with disabilities, but there are practical problems for which Argentina needs to find solutions. 59. Argentina is seriously working to address the problem of the management of the trials, in which there are problems of security but also of judicial strategy. There is no one single criteria or parameter and maybe several approaches will need to be combined, but certainly there is a need to
