The difference is about the style which is the most important one, and the reason is Chinese artist are almost very spritual and their painting is mor like their poem ,its light ,no too much colour because they are talking about spirt that should be very light and far from materialism thats why they use water color more than oil color and to honest painting ,colligraphy from them is something enternal and spirtual which is very much opposite of western painting .Western painting could be life style ,landscape ,nature..... there are huge differeances
between them.
Good luck my friend
