E/CN.4/1994/66 page 6 Minorities, as well as the need for more effective coordination between the Centre for Human Rights and organizations of the United Nations system which undertake operational activities for development. 28. The Special Rapporteur also welcomes the efforts of the Committee on the Elimination of Racial Discrimination to fulfil its mandate, and recognizes, with the Commission, the importance of activities aimed at directly assisting vulnerable groups to strengthen their participation in national, economic social and political life. The appeal to Governments 29. Lastly, the Special Rapporteur unreservedly endorses the appeal to all Governments to consider ratifying the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families. 30. He also reiterates the urgent call to all Governments to undertake immediate measures and to develop strong policies effectively to combat racism and eliminate discrimination. Other resolutions relevant to the mandate 31. In conclusion, the Special Rapporteur also wishes to recall that his future activities fall within the framework of Commission on Human Rights resolutions 1991/11, dated 22 February 1991 and 1992/8 of 21 February 1992. In the second resolution, the Commission reaffirmed its firm determination and its commitment to eradicate totally and unconditionally racism in all its forms, racial discrimination and apartheid. The Special Rapporteur also notes that the Commission’s consideration of these issues is founded on Sub-Commission on Prevention of Discrimination and Protection of Minorities resolutions 1990/1 and 1990/2 of 20 August 1992, as well as on General Assembly resolution 45/105 of 14 December 1990, in which the General Assembly declared once again that all forms of racism and racial discrimination, particularly in their institutionalized form, such as apartheid, or resulting from official doctrines of racial superiority or exclusivity, are among the most serious violations of human rights in the contemporary world. The Special Rapporteur also takes note of the substance of Commission resolution 1992/41 dated 28 February 1992 on human rights and thematic procedures. II. METHODS OF WORK OF THE SPECIAL RAPPORTEUR 32. The new mandate outlined above contains few indications as to the nature, framework and scope of the Special Rapporteur’s activities, the appropriate methodology and the sources of information on which he may draw. The mandate is nevertheless broad and important for the following reasons. 33. First of all, it is necessary to draw attention to the complexity and subtlety of the main theme, namely, contemporary forms of racism, racial discrimination, xenophobia and intolerance. At the very outset there is a need to redefine or refocus, by further refining, the concepts or notions of racism, of racial discrimination, of xenophobia and of intolerance, without overshadowing contemporary debates on human rights concepts.
