International law regulates state behavior by establishing legal frameworks that govern interactions between countries. These laws address issues such as human rights, trade, and territorial disputes, aiming to promote peace, security, and justice globally. Treaties and conventions serve as formal agreements that bind states to adhere to specific standards and obligations. When states violate these norms, they may face legal repercussions or diplomatic sanctions, promoting compliance. Overall, international law aims to create a structured and predictable global order, facilitating cooperation and conflict resolution among nations.
