This development was central to China's emergence as a free-market economy following the post-Mao reforms in 1979/82. At that time the west was doing its best to suppress gold to enhance confidence in paper currencies, releasing large quantities of bullion for others to buy. This is why the timing is important: it was an opportunity for China, a one-billion population country in the throes of rapid economic modernisation, to diversify growing trade surpluses from the dollar.
To my knowledge this subject has not been properly addressed by any private-sector analysts, which might explain why it is commonly thought that China's gold policy is a more recent development, and why even industry specialists show so little understanding of the true position. But in the thirty-one years since China's gold regulations were enacted, global mine production has increased above-ground stocks from an estimated 92,000 tonnes to 163,000 tonnes today, or 71,000 tonnes* ; and while the west was also reducing its stocks in a prolonged bear market all that gold was hoarded somewhere.
