International organizations, such as the United Nations, regulate state behavior through a framework of treaties, agreements, and monitoring mechanisms. They promote adherence to international law and encourage cooperation on global issues like human rights, trade, and security. By setting standards and facilitating dialogue, these organizations can influence state actions and encourage compliance with international norms. Additionally, they can impose sanctions or offer incentives, creating consequences for violations. This regulatory role aims to maintain peace, encourage global stability, and foster relationships that support cooperative solutions to complex, transnational challenges faced by states.
