The operation of the world's States dealing with this issue has been an interesting development in recent decades. Sustainable development in international politics and law has gained some importance, although questions and ambiguities remain. The purpose of this article is to present current position of sustainable development in international law concerning the function of States. In this paper, we try to demonstrate through the descriptive, analytical approach that sustainable development today has gone beyond the mere concept and entered into some aspects of soft international law and in some cases even difficult law.
