Prince El Hassan was awarded an Honorary Doctorate at the University of York in 2002 as recognition of his contribution to the field of post-war reconstruction and development.
On the international stage, many of Prince El Hassan's ideas and initiatives have acted as a catalyst. Addressing the 36th Session of the United Nations in 1981, His Royal Highness proposed the establishment of the New International Humanitarian Order, which led to a request by the Secretary General to found and co-chair the Independent Commission on International Humanitarian Issues (ICIHI). The final report of the Commission was adopted as a resolution at the 42nd General Assembly. A new initiative, the International Cultures Foundation was established in July 2002 to promote understanding among different cultures and to enhance dialogue between their thinkers and intellectuals. Its functions will be carried out through the Parliament of Cultures, located in Turkey and jointly founded by His Royal Highness and Professor Ihsan Dogramaci, Chairman of the Board of Trustees of Bilkent University. The first Assembly of the Parliament of Cultures took place in December 2003. In July 2003, as a joint initiative with John Marks from Search for Common Ground (SFCG), His Royal Highness launched Partners in Humanity. This project aims to improve understanding, build positive relationships and promote dialogue between the Muslim world and the U.S.
Prince El Hassan chairs and is a member of a number of international committees and organisations. These include: President of the Club of Rome (1999); President of the Board of Directors for the Center for Peace Studies and Conflict Resolution at the University of Oklahoma International Programs Center, USA; Co-Chair of the Independent Bureau for Humanitarian Issues; Member of the International Board of the Council on Foreign Relations; Member of the Board of Directors of the Nuclear Threat Initiative, Washington, DC (2002); Member of the Board of the South Centre (2001) and member of the Committee of Notables of the Institut Català de la Mediterrània (2001). His Royal Highness served as Chairman of the Policy Advisory Commission for the World Intellectual Property Organisation from 1999-2002; was a Member of the Executive Committee of the International Crisis Group; was an Honorary Member of UNESCO World Commission on Culture and Development; was a Member of the Committee of UNESCO International Interreligious Advisory Committee and was a Member of the Informal Advisory Group to the United Nations High Commissioner for Refugees.
In the field of religion, His Royal Highness' contacts and meetings have evolved into a systematic interfaith dialogue, primarily consisting of three ongoing consultations with the Orthodox Centre of the Ecumenical Patriarchate at Chambesy, Switzerland; the Pontifical Council for Inter-religious dialogue at the Vatican; and the Independent Commission on Christian-Muslim-Jewish Relations through the aegis of the Deanery of Windsor. In Jordan, His Royal Highness established the Royal Institute for Inter-Faith Studies in 1994 to complement these activities. In November, 1999 at the 7th World Assembly of the World Conference on Religion and Peace (WCRP), held in Amman, Prince El Hassan accepted the position of Moderator of the WCRP.
