Step 1: Understanding the Concept:
A federal system is a system of government where power is constitutionally divided between a central authority and constituent political units (like states or provinces). A unitary system is one where the central government is supreme.
Step 2: Detailed Explanation:
\[\begin{array}{rl} \bullet & \text{India, the United States of America, and Spain are all examples of countries with federal systems. The USA is a classic federation. India is described as a 'quasi-federal' state, but it has a clear constitutional division of powers between the Union and the States. Spain is also a highly decentralized state, functioning as a federation.} \\ \bullet & \text{China has a unitary system of government. All power is concentrated in the hands of the central government in Beijing, which is controlled by the Communist Party of China. While it has provinces and autonomous regions, their powers are delegated by the central government and are not constitutionally protected in the same way as in a federal system.} \\ \end{array}\]
Step 3: Final Answer:
China does not have a federal system of government; it has a unitary system.
