A multilateral treaty is an agreement among three or more countries aimed at addressing global issues, such as trade, environment, or security. These treaties are vital for fostering international cooperation and creating unified responses to challenges that transcend national borders. Multilateralism enhances diplomatic stability by encouraging dialogue and consensus-building among nations, promoting peaceful resolutions to conflicts. Examples include the Paris Agreement on climate change and the North Atlantic Treaty Organization (NATO). Through such frameworks, countries work together to establish norms and standards essential for addressing complex global interdependencies.
