蒙古國家安全中，地理因素是其最大影響。保持權力平衡是國家安全政策的基本原理。保持權力平衡意味著兩個鄰近國家關係的友善發展與平等合作，而非遵行其中一方或是受到其中一方的影響。權力平衡政策並非侷限於兩國關係，亦成為尋求第三方的政策基礎。確保國家安全的其中一個方式是，創造可與兩國相互競爭之第三方的利益，使其確保兩個鄰國不會受到其中一方過多的影響。 現在我們試圖利用多種方式以確保國家安全，例如權力平衡關係、主動開放式外交政策、不同盟、非核武區域等，不僅是地理因素，亦包含政治與經濟因素的考量，同時考量國際環境中的國家聲譽。 There is a significant big effect of geographical factor in the perception of national security of Mongolia. Preserving balance of power is the fundamental principle of national security policy. Preserving balance of power means to develop friendly and equal cooperation with two neighboring countries, not to follow either side one side, not to get under too much influence zone of either one. Balance of power policy is not limited to the relationship with the two neighboring countries only but it becomes the fundamental for the policy of seeking for the third partner. One of the methods of insuring national security is to create an interest of third partner, which can compete with the two neighbors, in our own country besides guarding from getting under too much influence zone of either one of the two neighboring countries. Today we are trying to insure our national security by using many methods such as to have a balanced power (relations), open and active foreign policy, to be None participating in alliance and None nuclear region etc considering not only the geographical factor but also political, economic factors as well as the reputation of the country in the world arena.
