In the preamble of Resolution 1170, the Security Council supported the engagement of the United Nations in Africa through diplomatic, economic, humanitarian, peacekeeping and other activities, and reaffirmed the obligation of all Member States to settle disputes in a peaceful manner. It was mindful of the 1993 Cairo Declaration which stipulated that the Organisation of African Unity (OAU) would anticipate and prevent conflicts as a primary objective and the African Nuclear Weapons Free Zone Treaty which was an important contribution to regional peace and security.
