Abstract
.The article reflects the historical development, formation, international legal framework of the Institute of international commercial arbitration and the scientific and theoretical views of representatives of this field. At the same time, today the settlement of international investment disputes in international law has an impact on international relations between states. Study international legal documents of a natural and peremptory nature and draw the necessary conclusions; such questions are reflected in the article. In addition, the advantages of international commercial arbitration over local courts, the process of adopting the UNCITRAL arbitration rules and its assessment as the most appropriate tool for resolving disputes today, include scientific views on the international legal regulation of international commercial arbitration and reforms in this area. There are also many contradictions between the settlement of international investment disputes through international commercial arbitration and the national legal system.
