2021年9月澳英美三边安全伙伴关系（AUKUS）成立以来，运行机制快速发展，在核心内涵上不断升级。对于澳英美三国建立安全伙伴关系，三方都有各自的考量，但澳大利亚最为积极活跃。国际社会对于这一新的安全机制反应不尽相同，大致分为以“明确支持”“明确反对”“无计可施或听任其便”三种态度类型划分的几大阵营，东盟成员国内部态度微妙，南太岛国作为直接利益攸关方，声音常常被忽略，但毫无疑问这造成了核扩散风险，将深刻影响该区域未来安全发展态势。
Since the establishment of AUKUS in September 2021，its operating mechanism of AUKUS has developed rapidly and its core content has continued to upgrade. Every party to AUKUS has its own consideration，while Australia plays the most active role. The new security mechanism has evoked different reactions in the international community，which can be roughly divided into three camps：“resolute opposition”，“nothing can be done about it” and “explicit support”. The attitudes of ASEAN countries to AUKUS are subtle，and the voices of South Pacific Island countries as direct stakeholders are often ignored. However，there is no doubt that AUKUS has caused risk of nuclear proliferation and will profoundly inform and shape future security situations in the region.
