International law regulates state interactions primarily through treaties, conventions, and customary practices. These legal frameworks outline the rights, obligations, and responsibilities of states in areas such as trade, human rights, and environmental protection. By adhering to international law, states can resolve disputes amicably, fostering cooperation and stability in the global arena. Additionally, international law establishes norms that guide how countries behave toward one another, promoting peace, security, and mutual respect. Enforcement mechanisms, such as international courts and tribunals, further ensure adherence to legal standards.
