Abstract: The subject of the study is the development, connections and prospects of the Indo-Pacific Strategy of the United States and the Indo-Pacific Regional Security Complex. The object of the study is the Indo-Pacific Strategy of the United States and the Indo-Pacific Regional Security Complex. In the theory of regional security complexes by B. Buzan and O.Vever, superpowers influence regional complexes and form them through the mechanism of "penetration". In today's multipolar world, it is extremely difficult for superpowers to fully penetrate the security system of a complex, but superpowers can still influence the internal structure of regional security complexes. Being the only superpower in the world after the Cold War, the United States plays an extremely important external role in promoting the emerging and developing Indo-Pacific regional security complex. This article, based on the theory of regional security complexes, analyzes the interaction of the United States, as an extraterritorial superpower, with the Indo-Pacific Security Complex, examines the impact of the Indo-Pacific Security Strategy on the region, and also explores the possibility of the United States achieving the ultimate goal of maintaining a hegemonic position through "penetration" into the Indo-Pacific security complex. The US Indo-Pacific strategy looks innovative, but in fact it is only a continuation and extension of the traditional Asia-Pacific strategy. Although it is difficult to ignore the role of the US Indo-Pacific Strategy in the formation of the security complex in the Indo-Pacific region, the internal forces of the complex and the laws of the development of the complex itself also lead to the fact that the implementation of the US Indo-Pacific Strategy faces great difficulties.
