Could China actually have 30,000 tonnes of gold in reserves?

My attention has just been drawn to a note put out by a very well respected analyst and China follower which postulates that China could actually be holding as much as 30,000 tonnes of gold in various government accounts and that within the next three years the nation will link the yuan to gold.

The suggestion that the nation holds this amount of gold has to be considered highly speculative.
