Since the end of the Cold War, the U.S., as a global superpower, has formulated diplomatic policies based on safeguarding liberal democracy and spreading democratic values. However, following the Arab Spring, the Middle East region has been plagued by increasing turmoil, becoming a battleground where Russia, China, and the U.S. compete to enhance their influence. Even the Gulf countries, key security partners of the U.S., have attempted to diversify their security partnerships and move away from reliance on the U.S.. In August 2023, BRICS accepted Saudi Arabia, Iran, UAE, and Egypt as new members. China and Russia are actively seeking an alternative to the U.S.-led international order and striving to expand the influence of the ‘Global South.’ Various analyses have been presented regarding the expansion of BRICS membership. Still most of them come from the perspectives of China, Russia, or the U.S. There is a lack of research on the perspectives and motivations of Middle Eastern states and their background for joining BRICS. Therefore, this study aims to analyze the background and context of why major Middle Eastern states have joined BRICS. Specifically,it will examine how major Middle Eastern states diversify their security efforts within the multipolar international order and discuss how they intend to utilize BRICS to strengthen their economic security. The study will shed light on the security and economic calculations behind the Middle Eastern states' decision to join BRICS and their efforts to enhance their security and economic well-being in a multipolar world order.
