This is a report to the Norwegian Ministry of Foreign Affairs on the potential impact of a possible Norwegian membership in the EU on Norwegian development aid. It consists of four parts of which the first describes development aid through the EU; the second reviews how this aid is organised; and the third deals with a related issue, viz. EU's trade policy towards the Third World. The fourth part discusses the consequences of a possible Norwegian EU membership on Norwegian development aid policy, and ends with an assessment of EU's own development aid from a Norwegian point of view.
