Not sure if you get into "The Daily Reckoning", but it is always a good read. ;
They have been going on about China's plans for gold for a while. A quick google turned up this, but they have written heaps more and have a fairly sophisticated outlook (if a little "out there").
"If Greg is right, the long term driver of the gold price will be China's attempt to corner the gold market. This will be the endgame of the currency war and the marginalisation of the US dollar. China will use yuan in bilateral trade and eventually open the currency up to full convertibility.
