What country is not a nation?

To determine which country is not a nation, we first need to understand the definitions of a "country" and a "nation".

A country is a distinct political entity that typically has defined borders, a government, and sovereignty recognized by other countries. It is a geopolitical and legal term used to describe a specific territory or region. Examples of countries include the United States, Germany, Brazil, and Australia.

On the other hand, a nation refers to a community of people who share common characteristics such as language, culture, history, and heritage. A nation can exist within a single country or span across multiple countries. Some examples of nations include the Kurds, the Basques, and the Roma.

While most countries are also nations, there are a few exceptions. For example, multinational countries such as China, Russia, and India are composed of multiple nations within their borders. These countries contain diverse ethnic, linguistic, and cultural groups that may identify with different nations.

In summary, a country that is not a nation would be a multinational country where multiple nations coexist within its borders. China, with its various ethnic groups, is often considered an example of such a country.
