DPR RI demonstrates its commitment to disaster management and climate change through its participation in international forums such as the APPF and IPU. Indonesia also initiated regional cooperation through IPPP, which highlights the importance of marine resource sustainability and mitigation of climate change impacts. Fiji, as an island nation vulnerable to natural disasters and climate change, has shown a positive response to Indonesia's parliamentary diplomacy.

This research concludes that Indonesia's parliamentary diplomacy has a significant influence in supporting the Fiji government's policies in dealing with environmental security threats, demonstrating the success of parliamentary diplomacy in the context of international cooperation for environmental and climate change issues.]]>
