Regional groups are collections of countries or areas that share common geographical, cultural, or economic characteristics. These groups often collaborate to address shared challenges, promote trade, and enhance political stability. Examples include the European Union and the African Union, which facilitate cooperation among member states. These groups can also focus on specific issues like environmental protection or security. By working together, regional groups aim to improve the well-being of their members and foster development. They often hold meetings and create agreements to strengthen ties and address regional concerns effectively.
