The Japanese decided to mingle after some alone time while the Chinese just thought they could deal with it. Now japan loves the west particularly america and china dismisses much of the western way of life. Japan, which is open to trade, and more open to dealing with the west on a more personal basis, and unfortunately is adopting a lot of western 'tastes', china, on the other hand, although they do some trading with the west, do it more at arm's length, is more xenophobic as a whole, and is trying to keep western ideals at bay.
