International law governs state interactions by establishing rules and norms that shape the conduct of countries in their relationships with one another. It encompasses treaties, agreements, and customary practices that outline responsibilities and rights of states in areas such as trade, human rights, and environmental protection. By providing a framework for resolving disputes and promoting cooperative behavior, international law aims to enhance global stability and security. Compliance with these legal standards fosters trust and predictability, facilitating diplomatic relations and cooperation among nations.
