Since the Persian Gulf region is rich in energy resources, it has always been a witness to the presence of out-regional powers. In order to politically and economically dominate the region in different eras, the great powers formulated short-term and long-term plans. Among all, in order to maintain its economic supremacy in the world and maintain the regional order, the United States of America paid special attention to the Persian Gulf. Therefore, it found the cooperation with the Arabic countries in line with its policies a step towards energy security of this region so that it could transport oil and gas resources to its country with spending a little amount of money. In the meantime, other major powers such as the European Union, Russia, and China need energy resources of the Persian Gulf for launching their industry. Obviously, this can increase the confrontation of great powers with each other in the Persian Gulf region. This study sought to investigate the reasons for the presence of powers in the Persian Gulf region. Therefore, research methodology in this study was analytical-descriptive, and data were collected through library research and fieldwork in order to analyze the consequences of the presence of out-regional powers in the Persian Gulf. Hence, with the prevalence of regional conflicts and strife in South West Asia, we witnessed the change of the geo-economic structure of gas and oil; the reason for the presence of world powers in this area is to first supply the needed energy of their country in order to run industry and to secondly limit their competitors’ energy supply.
