Environmental policies significantly influence international relations by fostering cooperation or conflict among nations. Policies addressing climate change, biodiversity, and resource management create an interconnectedness that necessitates collaboration, often leading to treaties like the Paris Agreement. However, differing national priorities can result in tensions, especially when economic interests clash with environmental commitments. As countries work towards sustainable development, the success or failure of environmental policies can either enhance diplomatic relations or strain them, highlighting the need for global cooperation on shared challenges.
