Foreign affairs refer to the relationships and interactions between countries. This includes diplomacy, trade agreements, and international treaties that help nations cooperate on various issues such as security, economic development, and environmental protection. Governments often have dedicated departments, like the Department of State in the United States, to manage these relationships and address global challenges. In addition to diplomacy, foreign affairs also encompass cultural exchanges and humanitarian efforts. Countries may collaborate on projects that promote education, health, and human rights. Organizations like the United Nations play a crucial role in facilitating dialogue and cooperation among nations to address global issues and maintain peace.
