This publication is the product of the Workshop on the Internationalisation of Policy Making which SIGMA organised in July 1995 at the College of Europe Natolin, near Warsaw. The purpose of the Workshop was to provide an opportunity to senior practitioners from Central and Eastern European countries to discuss the implications of the internationalisation of policies for governmental systems, and to examine structures and processes for the integration of domestic and international aspects of policy making. Drawing on the experience of OECD Member countries, and of different "generations" of Member countries of the European Union, the Workshop enabled the participants to compare different types of coordination mechanisms, and to draw practical advice for the improvement of policy-making systems.
