Indeed and the all of the high end cognac makers figured this out long ago.

I doubt that the Remy Martin people care that $3000 bottles of Louis XIII are being mixed with green tea or sprite in China every day.

On the topic of Chinese wine, I've had plenty of Chinese reds while traveling in wine producing areas of Shangdong and around Yinchuan and many of them are actually quite good. Not so good that I would try to get them in the US but good enough to serve with dinner and less likely to be fake than $$$ imported stuff.
