The episode in its entirety documents the relationship between China and Japan, giving them a big brother/little brother dynamic with the latter seeming rude and (initially at least) less well developed, but making fast progress into a rather smart if quiet sibling. My Asian history isn't really even close to being up to snuff enough to comment on that beyond noting that this was a relatively straight-laced episode, which does gain bonus points for featuring a panda, which can never be a bad thing.

We're also left this episode with a second trailer for "America's shed cleaning", which will apparantly be the focus of the next episode. Who knows what bizarre trails of history this will take us down? Mind you, said "trailer" does give us a pretty good hint...
