How did the institutions of imperial government in Han China differ from those established in Rome after Augustus?

The Roman and Han Empires were the largest empires the world had yet seen. While thousands of miles separated them, neither one had any influence on the other. Yet they experienced problems and came up with solutions that were similar. Take one of the following positions and discuss:
How did the institutions of imperial government in Han China differ from those established in Rome after Augustus? What might explain the difference? or
In what ways were the economic foundations of the Roman and the Han empires similar? How do you account for the similarity? How were they different? What were the consequences of the differences? or

As with all essays, you should begin with an introduction and end with a conclusion along with in-text documentation and a works cited page according to MLA. You must use at least 2 sources, one of those maybe your textbook.
