This paper’s aim is to emphasise the challenges faced by international cooperation in combating the financing of terrorism. It reviews the existing weaknesses and failures of each group of stakeholders participating in the CFT strategy: (1) the lack of coordination between international organisations and the huge burden of legislations created; (2) the limitations of the institutional framework that hamper the implementation of international standards at a national level; and (3) the high ongoing costs of implementing the risk approach for private non-state actors (financial and non-financial institutions). Finally, the paper concludes by pointing out which challenges must be confronted and which actions should be taken for enhancing international cooperation
