Abstract
This study examines the multifaceted nature of the complex security dilemma (CSD) in the Asia-Pacific region (APR) and China's strategic responses to emerging security challenges. Amid escalating geopolitical tensions, intensifying U.S.-China strategic competition, regional militarization, and evolving defense policies of Japan and South Korea, the security landscape has become increasingly intricate. The paper explores both traditional and non-traditional security dimensions, encompassing economic vulnerabilities, technological dependencies, and cyber threats. Particular emphasis is placed on the transformation of China's security strategy, notably through the Global Security Initiative (GSI), which seeks to foster an inclusive, cooperative, and sustainable regional security architecture. Through an analysis of regional security dynamics, the study identifies China's key policy mechanisms, including enhanced collaboration with ASEAN, the promotion of multilateral diplomacy, and resistance to bloc-based confrontations. The research employs a documentary-historical approach and qualitative analysis of state interactions to assess the evolving security environment. The findings suggest strategic measures to mitigate conflict potential in the region, including the establishment of crisis management frameworks and cooperative security mechanisms. By providing a nuanced understanding of regional security dynamics within the broader context of global transformations, this study contributes to ongoing scholarly discourse on Asia-Pacific security. Keywords: complex security dilemma, Asia-Pacific region, China, Global Security Initiative, regional stability, multilateral diplomacy.
