Treaties significantly influence international relations by formalizing agreements between states on various issues, including trade, security, and human rights. These legal instruments establish rights and obligations for the signatories, fostering cooperation and stability among nations. Treaties can resolve conflicts, promote peace, and facilitate collaboration on pressing global challenges such as climate change and terrorism. However, the effectiveness of treaties depends on compliance and enforcement mechanisms, as violations can lead to tensions or conflicts. Overall, treaties are essential tools for diplomacy, shaping the dynamics of global interactions.
