Regional integration refers to the process where states enter agreements to enhance cooperation through regional institutions and rules. The key objectives of regional integration include strengthening trade, private sector development, economic growth, good governance, and reducing social exclusion. Regional trade agreements (RTAs) like the European Union (EU) and North American Free Trade Agreement (NAFTA) aim to reduce tariffs and trade barriers between member nations. Other RTAs discussed include the Association of Southeast Asian Nations (ASEAN), South Asian Association for Regional Cooperation (SAARC), and the South Asian Free Trade Area (SAFTA) which seeks to establish a free trade area across South Asia.
