Chinese Gold Mining Production

Despite the massive growth in Chinese gold mining production, it may be set to slow significantly. A slow down in Chinese gold mining supply would mean that in order to satisfy Chinese gold demand which, according to the World Gold Council, will grow 20% over the next three years, China will need to find additional sources of gold.
