ASEAN covers ten countries in Southeast Asia, and its "centrality" is the key to ASEAN's positioning, and the "talisman" that allows it to play a key role in the regional security architecture and regional order arrangement. ASEAN makes use of its unique role to develop a unique "ASEAN way", establish an ASEAN-centered multi-mechanism platform, and use the strategy of "balanced diplomacy" to effectively maintain the interaction between regional and extra-territorial countries and maintain its own "centrality". However, due to the special characteristics of Southeast Asia, with the new development of Sino-US relations, ASEAN is becoming an important force in the power game between China and the US, and with the escalation of the US Indo-Pacific strategy, ASEAN will face the risk of being decentered and marginalized in the Indo-Pacific region. Therefore, while the ASEAN organization has made great diplomatic achievements in recent years, it is also accompanied by numerous challenges to its future development.
