Foreign relations is the study of the interactions and relationships between different countries on a diplomatic, economic, political, and social level. This field of research analyzes how nations engage with each other through negotiations, treaties, alliances, trade agreements, and other forms of cooperation or conflict. Scholars in this area often examine the ways in which foreign policy decisions are made, the role of international organizations such as the United Nations, and the impact of globalization on global affairs. Foreign relations research is crucial for understanding and predicting the dynamics of the international system and promoting peaceful and mutually beneficial interactions between countries.
