氣候外交視角下的中國－－太平洋島國關係：合作、影響與戰略考量

China-Pacific Island Relations through the Lens of Climate Diplomacy: Cooperation, Influence and Strategic Implications

太平洋島國因日益加劇的氣候變遷影響，面臨嚴重的生存與發展挑戰。在此背景下，中國透過多元的援助方式，積極推動以氣候援助為核心的外交政策，以提升島國的應變能力。然而，中國的氣候外交舉措不僅旨在強化島國的氣候韌性，更是鞏固其區域影響力的重要途徑，具有深刻的戰略意義。然而，由於中國在該區域影響力的擴大，引發美國等西方國家的反制措施及部分島國對中國外交政策的警惕。故此，本文透過探討中國在索羅門群島、斐濟及巴布亞紐幾內亞的援助內容，分析其氣候外交措施及成效，並指出儘管中國投入大量援助項目，但在美中競爭的格局下，中國氣候外交策略的實施與成效受到明顯制約。

Pacific Island countries encounter significant challenges to their survival and development as a result of the increasingly severe impacts of climate change. In light of this situation, China has actively pursued a climate aid-centered diplomatic approach, providing various forms of assistance aimed at enhancing the resilience of these nations. However, it is important to note that China's climate diplomacy is not exclusively concerned with strengthening the climate resilience of Pacific Island countries; it also serves as a strategic mechanism for consolidating its regional influence, which carries important geopolitical implications. The expansion of China's influence in the Pacific region has elicited countermeasures from the United States and other Western nations, as well as heightened caution among certain Pacific Island countries regarding China's diplomatic strategies. This paper critically examines China's climate aid initiatives in the Solomon Islands, Fiji, and Papua New Guinea, evaluating their measures and effectiveness. Despite China's considerable investment in aid projects, the implementation and outcomes of its climate diplomacy strategies remain significantly constrained within the broader framework of U.S.-China geopolitical competition.
