E/CN.4/1994/31 page 9 18. In general, the Special Rapporteur has welcomed the accent placed by the Commission on cooperation among the various mechanisms called upon to address the problem of torture and analogous grave human rights violations. He has noted, in particular, resolution 1993/40, in paragraph 16 of which the Commission considered it desirable that the Special Rapporteur should continue to have a further exchange of views with the various mechanisms and bodies entrusted with the task of combating torture, in particular with a view to enhancing further their effectiveness and mutual cooperation; and resolution 1993/47, in paragraph 9 of which the Commission encouraged the thematic special rapporteurs and working groups to continue to cooperate closely with relevant treaty bodies and country rapporteurs. 19. Moreover, the Vienna Declaration and Programme of Action of the World Conference on Human Rights states in Part II: "1. The World Conference on Human Rights recommends increased coordination in support of human rights and fundamental freedoms within the United Nations system. To this end, the World Conference on Human Rights urges all United Nations organs, bodies and the specialized agencies whose activities deal with human rights to cooperate in order to strengthen, rationalize and streamline their activities, taking into account the need to avoid unnecessary duplication. The World Conference on Human Rights also recommends to the Secretary-General that high-level officials of relevant United Nations bodies and specialized agencies at their annual meeting, besides coordinating their activities, also assess the impact of their strategies and policies on the enjoyment of all human rights." "88. The World Conference on Human Rights recommends that the State parties to international human rights instruments, the General Assembly and the Economic and Social Council should consider studying the existing human rights treaty bodies and the various thematic mechanisms and procedures with a view to promoting greater efficiency and effectiveness through better coordination of the various bodies, mechanisms and procedures, taking into account the need to avoid unnecessary duplication and overlapping of their mandates and tasks." 20. In this context the Special Rapporteur found extremely valuable the formal and informal contacts with other procedures that were afforded by the Fourth Preparatory Committee meeting and the World Conference itself. These and other informal and formal meetings, such as the one held in December 1993 with the Working Group on Arbitrary Detention, have permitted him to stay abreast of developments in the methods of work of the other procedures, especially the thematic ones, with a view not only to avoiding duplication of the sort addressed in the previous paragraphs, but also to harmonizing their working methods and reporting procedures. The Special Rapporteur considers as potentially productive the Commission’s request to the Secretary-General, in its resolution 1993/47, that he consider the possibility of convening a meeting of all the thematic special rapporteurs and the Chairmen of the working groups of the Commission in order to enable an exchange of views and closer cooperation.
