One recurring problem with all this talk about the Chinese clones copying American artists’ work centers primarily on money more than having your work copied.  I went to the site "Contemporary Chinese Art" that you list at the bottom of this site. Frankly, most of what I viewed was terrible. If people want to pay millions for this, I hope they are happy. Be that as it may.
Money is always an issue but money should never be the central issue. I've heard both sides of this argument and I'm sure there will be continued discussion about money ad infinitum. The underlying reason for artists to paint is produce art in a way that others will see the world differently. See something they overlook in their life. Or if you will produce something of beauty. If we are to be "more Chinese" for the sake of making millions on every sale, artists will sacrifice something we will never get back again. Yes, I appreciate sales and wish more of them, but I'm unwilling to paint solely for sales. This may mean I will live eternally in obscurity with a few patrons purchasing my work because they love it and not for investment alone. So be it.
"You must paint what you know" has been said to me many times. I find this to be true. Political art will with us for years to come. When all is said and done I sit and relax in my home looking at art that pleases and satisfies me. Interestingly, the Chinese artists that have immigrated to the USA paint a very different art. I think it's because their frame of reference has also changed. They now live in a society where they can truly express their inner feelings free from the turmoil of oppression and political dogma.
