The European Parliament adopted on 10 July 1990 a Resolution on scientific and technological cooperation between the European Communities and other European countries. The Resolution includes aspects of cooperation with the countries of Central and Eastern Europe and proposes two medium-term aid programmes for these countries: EAST (European Assistance for Science and Technology) and GREEN (General Research in Environment for Eastern Nations). To bridge the period until implementation of these programmes, it proposes that emergency aid be granted under the title LET'S GO EAST (Let European Technicians and Scientist Go East). This aid would finance, inter alia, the sending of teams of scientists and experts from the European Communities to the Eastern European countries for a period of three to six months. The Parliament also proposes that the programmes on human resources and mobility (SCIENCE, SPES, Major Installations) in the framework programme for RTD be opened up to Central and Eastern European countries. It believes that the EAST and GREEN programmes should follow on directly from the framework programme for RTD and be integrated in the fourth framework programme, with a further adequate budgetary appropriation being allocated. The Parliament proposes furthermore that in the framework of the EAST and GREEN programmes - which should have a maximum life of 8 years - the Community should make available for the first four years an extraordinary financial contribution equivalent to 10% of appropriations of the framework programme for RTD, with the proviso that this percentage is gradually diminished in the following years.
