THE INDO-PACIFIC AS A STRATEGIC ARENA: EVOLVING SECURITY ALLIANCES AND DEEPENING POWER RIVALRIES

Abstract

This paper examines the transformation of the Indo-Pacific into the central arena for global strategic competition. It argues that the intensifying rivalry between the United States and the People's Republic of China is the primary driver reshaping the regional security architecture. This rivalry has catalyzed the formation and strengthening of countervailing coalitions, notably the Quadrilateral Security Dialogue (QUAD) and the AUKUS pact, while simultaneously challenging the centrality of established ASEAN-led institutions. Through a qualitative analysis of strategic documents, academic literature, and policy reports from 2020-2025, this study dissects the interplay of military modernization, nuclear deterrence, and the weaponization of the economic-security nexus, particularly in critical technology supply chains. The findings indicate a shift towards a more fragmented and contested regional order, characterized by a complex web of overlapping bilateral and minilateral arrangements designed to balance against China's rise. While these alignments enhance deterrence, they also heighten the risks of miscalculation and escalation. The paper concludes with policy recommendations for strengthening cooperative security mechanisms, managing geoeconomic friction, and establishing robust crisis communication channels to ensure regional stability.
