Diplomatic relations influence international politics by facilitating communication and cooperation between countries on various issues, such as trade, security, and human rights. Strong diplomatic ties enable nations to negotiate treaties, resolve conflicts, and collaborate on shared challenges effectively. Good diplomatic practices foster mutual respect and understanding, contributing to regional and global stability. Conversely, strained relations can lead to tensions, isolation, and conflict. Diplomatic efforts play a crucial role in shaping foreign policies that reflect a nation's values and interests within the global community.
