1987年,日本提出「倉成主義」後,開啟了日本的南太平洋外交戰略,並於1997年主導成立「日本-太平洋島國峰會」(Pacific Islands Leaders Meeting, PALM),作為定期互動的對話機制與平台。隨著國際政治經濟的劇烈變化,南太平洋地區對當前日本的戰略利益,可從安全、經濟與外交面向理解。南太平洋對日本的安全利益,主要是維護運輸通道、建立法治海洋秩序,以及制衡中國擴張威脅。南太平洋對日本的經濟利益,主要是鞏固遠洋漁業、爭取礦產資源、提升貿易投資,以及拓展能源供應。南太平洋對日本的外交利益,則在於爭取成為聯合國安理會常任理事國、實現政治大國,以及國際事務的合作。
After Japan proposed the "Kuranari Doctrine" in 1987,Tokyo launched its South Pacific diplomatic strategy. This also led to the establishment of the Japan-Pacific Islands Leaders Meeting (PALM) as a regular dialogue platform in 1997. With the drastic changes in international politics and economy, the strategic interests of the South Pacific for Japan can be understood in terms of security, economy and diplomacy. The security value of the South Pacific to Japan is mainly to maintain transportation routes, establish a legal maritime order, and balance the threat of Chinese expansion. Japan's economic interests in the South Pacific, meanwhile, are mainly to consolidate distant-water fisheries, mineral resources, trade and investment, and energy supply. On the diplomatic front, Japan's interests in the South Pacific lie in Tokyo's efforts to become a permanent member of the UN Security Council, consolidating political power, and cooperation in international affairs.
