The Secretary-General Kofi Annan was requested to submit reports on the socio-economic implications of the sanctions and, along with ECOWAS, on compliance of the Liberian government with the Security Council's demands and their implementation. States in the region were called upon to strengthen measures against the proliferation of small arms, light weapons and mercenary activities. Furthermore, the Secretary-General was requested to an expert panel consisting of six members to conduct a follow-up mission to Liberia and neighbouring states on the Liberian government's compliance; investigate the illegal use of revenues; assess the socio-economic impact of the sanctions; and report with observations and recommendations to the Council by 7 October 2003.
