if i may make a pretty general assumption, Europe and China in terms of size and population do have some similarities in history. Geography is just as diverse, so do cultures (yes regional differences among chinese population are quite significant). In the ancient world, both had giant empires unifying much of the land, with Rome in the West and Han in the East. But soon after, there is the divergence.
Europe would never have another empire of similiar dominance and so much land and population under one state; today it has over two dozen countries. China on the other hand would have more dynasties to come and unifying the land, to this day.
why this difference?
