A more thorough explanation: Regional international law refers to a set of legal rules and principles that govern the relationships and interactions between states within a specific geographic region. These rules are established through agreements, treaties, and conventions among the states within that region, and they may address various issues such as trade, security, human rights, and environmental protection. Regional international law complements and sometimes supplements the broader framework of international law that applies globally to all states.
Example: The regional international law governing trade agreements between countries in Southeast Asia is known as the ASEAN Free Trade Area.
