The foreign ministers of India, Japan, Australia, and the United States convened in New Delhi on May 26, 2026, to implement operational initiatives aimed at enhancing regional security and economic resilience.

印度、日本、澳洲與美國的外交部長於 2026 年 5 月 26 日在新德里舉行會議，旨在實施旨在增強區域安全與經濟韌性的操作倡議。

The 11th Quad Foreign Ministers' Meeting was characterized by a transition from consultative dialogue toward a 'partnership of action.' Central to this shift was the introduction of the Indo-Pacific Energy Security Initiative and the establishment of a Fuel Security Forum, necessitated by the disruption of the Strait of Hormuz following the February 28 US-Israeli military operation against Iran. Furthermore, the alliance formalized a Critical Minerals Framework to diversify supply chains and reduce dependence on single-source monopolies, alongside a maritime surveillance collaboration to integrate real-time data sharing. In a significant infrastructural expansion, the Quad announced a joint port development project in Fiji, representing the grouping's first collective infrastructure venture.

第 11 次 Quad 外長會議的特點在於從諮詢對話轉向「行動夥伴關係」。此次轉型的核心在於推出印太能源安全倡議及成立燃料安全論壇，這是由於 2 月 28 日美以對伊朗採取軍事行動後，導致霍爾木茲海峽受阻所致。此外，該同盟正式制定了關鍵礦物框架以實現供應鏈多元化，減少對單一來源壟斷的依賴，並同步建立海上監控合作以整合即時數據共享。在基礎設施的重大擴展方面，Quad 宣布在斐濟開展聯合港口開發項目，代表該小組首次進行集體基礎設施投資。

Historically, the coalition's cohesion has been attenuated by the transactional nature of the second Trump administration. Analysts have noted a perceived American pivot toward the Western Hemisphere and Middle East, evidenced by the redeployment of naval assets from the Asia-Pacific. This strategic drift, compounded by a rapprochement between President Trump and President Xi Jinping—highlighted by the 'G2' conceptualization—has induced anxiety among allies regarding US reliability. Consequently, member states have pursued hedging strategies; Japan has increased its defense expenditure to 2% of GDP and expanded partnerships with the UK and Philippines, while India has intensified its 'strategic autonomy' through a pivot toward European nations and a diplomatic reset with Canada under Prime Minister Mark Carney.

從歷史來看，由於第二任川普政府的交易本質，該聯盟的凝聚力有所削弱。分析師指出，美國似乎將重心轉向西半球與中東，亞太地區海軍資產的重新部署便證明了這一點。這種戰略漂移，加上川普總統與習近平主席之間的關係回暖（以「G2」概念為代表），引發了盟友對美國可靠性的焦慮。因此，成員國採取了對沖策略：日本將國防開支提高至 GDP 的 2%，並擴大與英國及菲律賓的夥伴關係；而印度則透過向歐洲國家傾斜，以及在總理馬克·卡尼領導下與加拿大重啟外交關係，來強化其「戰略自主」。

Security deliberations also addressed asymmetric threats, with the Quad issuing a joint condemnation of cross-border terrorism, specifically referencing the April 2025 Pahalgam attack and the Bondi Beach incident. This alignment contrasts with the friction observed in other bilateral spheres, such as the ongoing disputes between India and Canada over allegations of transnational repression, and the concerns raised by Australia regarding the production rates of Virginia-class submarines under the AUKUS pact. Beijing has consistently characterized the Quad as an 'exclusive clique' and a containment structure, while simultaneously utilizing 'thin diplomacy' to establish broad, low-depth partnerships across divergent geopolitical lines.

安全討論還涉及非對稱威脅，Quad 發布聯合聲明譴責跨境恐怖主義，特別提到 2025 年 4 月的帕哈爾格姆襲擊及邦戴海灘事件。這種一致性與其他雙邊領域的摩擦形成對比，例如印度與加拿大之間關於跨國鎮壓指控的持續爭議，以及澳洲對 AUKUS 協定下維吉尼亞級潛艇生產速度的憂慮。北京一貫將 Quad 定義為「排他性小圈子」與圍堵結構，同時利用「薄外交」在分歧的地緣政治路線上建立廣泛且淺層的夥伴關係。

The Quad has attempted to stabilize its strategic utility through concrete deliverables, though its long-term coherence remains contingent upon the consistency of US engagement and the resolution of internal transactional tensions.

Quad 試圖透過具體成果來穩定其戰略效用，儘管其長期凝聚力仍取決於美國參與的一致性以及內部交易緊張關係的解決。
