According to google:
Are you allowed to own gold in China?
All gold and silver held by domestic units, with the exception of raw materials, equipment, household utensils and mementos which the People's Bank of China has permitted to be kept, must be sold to the People's Bank of China. No gold and silver may be personally disposed of or kept without authorization.
That reads to me like Chinese citizens cannot own gold or silver without permission from the authorities. So in other words the government keep tabs on every bit of gold bought and sold so certain citizens do not start creating wealth outside of the system. Probably lower class citizens who according to opinions of government entities do not meet the finacial requirements to store gold.
So people think this could not happen to us?? Well yes, in this usa, from 1933 to 1974 it was illegal for U.S. citizens to own gold in the form of gold bullion, without a special license.
Would they confiscate gold again? Yes. Absolutely they would to fund whatever psychopathic plans they have next and those dealers have a nice list with all the details of every poor sod storing gold in the uk. Seriously, even if you move your physical metal immediately after a crisis shtf situation, they are coming for you to ask where it is and what are you going to say? Iv sold it? When? Who did you sell it to? And then your in a whole world of trouble, better to just hand it over.
