There are both implicit and explicit links between the Paris Declaration on Aid effectiveness and UNCAC preventive measures, especially in the area of mutual accountability, institution building through increased public accountability and participation or the improvement of national public procurement and public financial management systems (PFM). Within this framework however, the provision of budget support, while intended to enhance aid effectiveness as recommended by the Paris Declaration, has not demonstrated conclusively its ability to effectively address corruption risks. The UNCAC can be an essential contribution to the policy dialogue on corruption as it provides an international framework setting common standards. Budget support recipient countries can be supported in their anti-corruption efforts through the UNCAC technical assistance and exchange of information provisions.
