Regional Economic Organizations are groups formed by countries in a specific area to promote economic cooperation and development. These organizations aim to enhance trade, investment, and economic stability among member nations. Examples include the European Union and the Association of Southeast Asian Nations (ASEAN), which facilitate collaboration on various economic issues. These organizations often create agreements that reduce trade barriers, harmonize regulations, and encourage joint projects. By working together, member countries can leverage their resources and strengths, leading to improved economic growth and prosperity for the region as a whole.
