I don't think the chinese government will let 人民幣自由對換 before the olympic. Because it is too risky, nobody knows how much effect it will have to the economy. Besides there will be a lot of touist in this 2 years, chinese government don't want it to rise too much to affect the tourist industry.
現時價格可入貨嗎? yes, I have some myself. But I will sell my chinese shares and change it to 人民幣 just before the olympic.
