Member States are countries that are part of an international organization, such as the United Nations or the European Union. Each Member State has its own government and laws but agrees to work together on common goals and issues, such as trade, security, and human rights. Membership in these organizations often requires countries to adhere to certain rules and standards. Member States participate in decision-making processes, contribute to budgets, and collaborate on various initiatives to promote peace, stability, and development within the global community.
