Regional security refers to the measures and strategies that countries within a specific area take to ensure their safety and stability. This can involve military cooperation, intelligence sharing, and diplomatic efforts to prevent conflicts. Countries often work together to address common threats, such as terrorism or territorial disputes, to maintain peace in their region. Organizations like the North Atlantic Treaty Organization (NATO) or the Association of Southeast Asian Nations (ASEAN) play a crucial role in promoting regional security. They facilitate dialogue among member states and coordinate responses to security challenges, helping to build trust and foster collaboration among nations.
