A more thorough explanation:

INTERNATIONAL RELATIONS

International relations is the study of how countries interact with each other. It includes things like politics, economics, and diplomacy. It's also the name of the academic subject that teaches about these things.

• When the United States and China negotiate a trade deal, that's an example of international relations.
• When the United Nations tries to prevent wars between countries, that's an example of international relations.
• When a student takes a class on international relations, they might learn about the history of diplomacy between countries.

These examples show how international relations involves interactions between countries on a global scale. It's important to study international relations so that we can understand how countries work together (or don't work together) and how we can solve problems that affect the whole world.
