As discussed the other day, China is probably importing 100 tonnes a month - and that's not including their internally mined Gold.
GoldSilver.com (Mike Maloney's group) have published the following graph. I don't know if their figures are accurate - the only obvious caveat is that this is Chinese Government reserves + Gold held by the Chinese people.
With that caveat in mind, here's the graph. It shows the likely Chinese reserves at about 7000 tonnes.
For perspective: this doesn't make China the largest holder of Gold. The people of India (by themselves, not their Government) are thought to have perhaps 10,000 tonnes: quite a lot of it on Temple roofs :0)
Although of course the Indian Government is scandalously trying any and all means to divest the Indians of their Gold, whereas China seems to be pragmatically moving away from the fiat system.
