The resolution extended sanctions relating to rough diamonds and travel against Liberia for a further 12 months beginning at 00.01 EST on 7 May 2002 and a review would take place at the end of the period on whether the Liberian government had complied.[3] Furthermore, it was called upon to set up an effective, transparent and verifiable certificate of origin regime, taking into account the international Kimberley Process Certification Scheme. Rough diamonds under the control of the Liberian government would be exempt from the embargo.
