Changes in Central and Eastern Europe and in the previous USSR which resulted in disintegration of the market in former socialist countries have created conditions for constructing new kinds of contacts with individual EC countries and EC as a whole. Thre European treaty of association between the member countries of EC on the one hand and CSFR on the other hand is a particular expression of these new contacts. The main goal of the Association is, besides the development of a political dialogue, to propose a free movement of goods, services, capital, and working people on the areas of signatories to the Treaty. The problem of human environment forms the object of only one article of the Treaty but encircles even the prevailing part of cooperation and main forms of its realization, but it is only a frame expression of demands on cooperation in human environment that will be specified in special agreements and/or programmes after the ratification by all countries of the Treaty. The association agreement takes care of all parts of human environment – air, water, soil, forest, flora, fauna, and landscape ecology as well. At the same time it is assumed that CSFR will take an active part in European informative and monitoring network and will use all possible contacts and forms of cooperation with European Agency for Human Environment.
