Diplomacy is a fundamental concept in international relations, serving as the primary means through which countries manage their interactions and resolve conflicts. It involves negotiations, dialogue, and cooperation between states to advance mutual interests, address global challenges, and promote peace. Effective diplomacy can help build alliances, prevent wars, and facilitate trade and cultural exchange. The practice often requires a delicate balance of national interests and global responsibilities, emphasizing the importance of communication and understanding in maintaining international order and fostering collaboration on critical issues.
