The Pacific Island nations, as one of the regions most affected by climate change globally, are highly susceptible to rising sea levels, storm surges, floods, and tsunamis, facing numerous challenges. Additionally, their economies largely depend on fisheries and tourism, industries also threatened by climate change and ocean acidification. At the 27th United Nations Climate Change Conference (COP27), small island nations and developing countries are taking the lead in highlighting the importance of oceans as a climate solution. Concurrently, China has consistently emphasized the unique difficulties and concerns faced by Pacific Island nations in addressing climate change. On May 30, 2022, President Xi Jinping, in his address at the Second China-Pacific Island Countries Foreign Ministers' Meeting, stated, China is willing to work together with Pacific Island nations to build a closer China-Pacific Island community with a shared future. Therefore, jointly exploring the topic of Pacific Island nations' responses to climate change and sustainable development is profoundly significant.【More】
