The committee established in Resolution 1132 was to gather information on measures taken by countries to implement the diamond import ban, investigation violations and make recommendations on improving the sanctions regime. All countries and organisations were instructed to strictly enforce the measures. It was also requested to co-operate with similar committees established in Resolution 985 (1995) on Liberia and Resolution 864 (1993) on Angola. Meanwhile, the committee was also asked to conduct an exploratory hearing in New York City by 31 July 2000 to assess the role of diamonds in the civil war in Sierra Leone.
