Both Croatia and the Federal Republic of Yugoslavia (Serbia and Montenegro) were urged to fully implement an agreement on the normalisation of their relations, cease violations of the demilitarisation regime, reduce tension and to ensure freedom of movement to United Nations observers. The Secretary-General Kofi Annan was asked to report by 15 October 1999 on recommendations for confidence-building measures between the two parties. Finally, the Stabilisation Force, authorised in Resolution 1088 (1996) and extended by Resolution 1247 (1999), was required to co-operate with UNMOP.
