Reporting on a series of workshops, a conference, and various study groups held during a three-month special program during the 39th General Assembly of the United Nations, this publication focuses on challenges presented to the United Nation's system of nearly 40 international organizations, regional institutions, international non-governmental associations, and communication networks. The keynote address, "Will the 1990's be '1984'?" (Sir Sridath Ramphal), is followed by summaires of remarks by respondents Sir John Thomson, Beatrice Harretche, and Ambassador Donald Mills. Next, summaries of remarks by members of a panel (Richard Gardner, Donald Mills, Michel Doo-Kinque, and Rosalyn Harris) are presented. Names of the facilitators and rapporteurs of the three conference working groups are then listed, followed by reports from the total conference based on the three broad workshop areas: (1) "Future Situations Confronting Humanitiy which Require Multilateral Co-Operation," (2) "Restructuring Multilateral Co-Operation and Organizations," and (3) "Agents in Advancing Multilateralism in International Relations and Institutions." A keynote statement on the future of the United Nations by Maurice Strong, 15 main recommendations from the conference, and a list of participants concludes the report. (LH)
