The smuggling of diamonds is investigated in this report, specifically from the Central African Republic into Cameroon. The focus is also on the impact that this illicit trade has on Cameroon’s internal controls as well as the broader integrity of the diamond supply chain. The report describes the methods used and the key actors involved in this illicit trade. It concludes that the Kimberley Process and front line countries like Cameroon need to do more to interrupt the illicit trade of conflict diamonds from CAR and support each other in taking action.
