This paper sets out an approach to deciding what forms of aid are appropriate in specific country circumstances. It does not address how much aid a country should receive. The focus is on the choice between different types of financial aid, though some of the principles are also relevant to technical assistance. The focus is on Government to Government aid. It considers briefly the circumstances in which there may be a case within country programmes for direct support to NGOs or private sector partners, but does not pretend to offer an adequate treatment of emergency aid, nor of the approach to financial support where normal Governance has broken down.
