China does not have capital gain tax from stock trade.
http://en.wikipedia.org/wiki/Capital_gains_tax
The rumor of imposing capital gain tax in China caused Shanghai stock market to drop nearly 9% in a single day last week, which triggered stock market in New York to drop about 4% a few hours later. But I think that it was a correction in Chinese stockmarket. Chinese stock market increased 125% last year after long time of depression. I personally lost more than 10% of my investment last week.
