On July 19, 2000, the World Diamond Congress adopted at Antwerp a resolution to reinforce the diamond industry's ability to block sales of conflict diamonds.[23] Thereafter, with growing international pressure from Global Witness and other NGOs, meetings were hosted with diamond-producing countries over three years, concluding in the establishment of an international diamond certification scheme in January 2003. The certification system on the export and import of diamonds, known as the KCPS, was called by the resolution, imposing legislation in all countries to accept shipment of only officially sealed packages of diamonds accompanied by a KP certificate guaranteeing that they were conflict-free. Anyone found trafficking conflict diamonds will be indicted of criminal charges, while bans were to be imposed on individuals found trading those stones from diamond bourses under the World Federation of Diamond Bourses.
