Some of my immediate observations were:
1. The legalist idea of having the laws written and posted is often attributed to the Romans.
2. Mencius' idea of humans being basically good and Sun Zi's belief that humans are basically good, relates directly to the enlightenment thinkers Locke and Hobbes.
It seems that in addition to the many inventions and societal constructs that the European nations adopted from Africa and the middle east, ideas from Asia were coopted as well. Of course people in isolated locations come up with ideas based on necessity, however so much of the philosophical underpinnings noticeable is western society are not given proper recognition for their origins. Juxtapose that with the tendency of western cultures to criticize the philosophical foundations of those same nations on which their society's laws are based.
