The study attempts to present the impact of Russian policy on Saudi Arabia in terms of economic security. Analyses of primary data on the quantitative states of the possessed oil and gas resources and their annual consumption, as well as the state of essential armaments of Russia and Saudi Arabia were carried out and evaluated. As a result of the analysis of the literature of the research, it was observed that the potential of Russian-Saudi military cooperation is unrealized. One of the goals of Russian policy is to seek to limit the influence of both Saudi Arabia and the United States in the Middle East region. This limitation allows Saudi Arabia itself to not dictate world oil prices. The United States, on the other hand, due to its huge demand for oil, is forced to pursue such a policy in order to be guaranteed an adequate price and continuity of supply to meet its oil needs now and in the future.
