Unitary and Federal states
France and China are typically seen as countries with a central government that has the most power over smaller parts of the country.
Mexico and India both have federal governments, which means that they share power between the central government and smaller parts of the country.
This allows the smaller parts to have some freedom and make decisions on their own within certain limits.
