Sino-Japanese relations through history.

Well, afaik, Japan tends to feel superior over those who are worse off, but tends to praise and worship those who are better.  Like before Meiji revolution, they did consider Ming and other Chinese dynasties as superior, and adopted many of its policies, like the System of Government and it's hieroarchy.  But after they've seen European supremacy over China, they started adopting the Europeans, and starting warshipping it's ideals. 

Currently Japan is better off economically than China, thus Japanese won't care about them.  Unless China economically-wise defeats Japan, which would come in a couple of years.
