Jim Rogers on China currency policy

Via www.commodityonline.com
Jim Rogers: No economy can become world class with a blocked currency. That's never happened in history. Throughout history people with blocked currencies have eventually declined. China knows that; I'm not the only person who's read some history. They have been opening their currency for the past five years. Every quarter, every year, they open a little more. I thought they would have made it freely convertible by now. In my view, it's good for China, good for the Chinese [people], and good for the world. The sooner they make it convertible, the better.
I cannot tell the Chinese what to do; I don't want to tell them what to do. But yes, they are opening up and it has been good for the world so far. It's certainly been good for many parts of the world [that] sell to China; [they are] much, much better off than they were 20 years ago. So something has gone right. [China is] going to have to open their currency and make it completely convertible some day.
Again, I thought they would have done it by now. China doesn't have anything to worry about anymore. They are the second largest economy in the world and they have gigantic foreign exchange reserves. I don't think they should worry, but they seem to be worried for whatever reason.
