Explanation:

A state, to be recognized as a state, has to fulfill certain criteria. These are related to the people, the sovereignty of the region, specified territory borders and the government in the region.

This population resides within a certain territory with specified borders and is ruled by a sovereign government. Such a setting can be recognized as a state.
