UNTIED AID

Official Development Assistance for which the associated goods and services may be fully and freely procured in substantially all countries.

TIED AID CREDITS

Official or officially supported Loans, credits or Associated Financing packages (qq.v.) where procurement of the goods or services involved is limited to the donor country or to a group of countries which does not include substantially all developing countries (or CEEC/NIS countries in transition, cf. PARTIALLY UNTIED AID). Tied Aid Credits are subject to certain disciplines concerning their concessionality levels, the countries to which they may be directed, and their developmental relevance so as to avoid using aid funds on projects that would be commercially viable with private finance, and to ensure that recipient countries receive good value.

PARTIALLY UNTIED AID

Official Development Assistance (or Official Aid) for which the associated goods and services must be procured in the donor country or among a restricted group of other countries, which must however include substantially all developing countries.
