You do know that you can buy gold at any Chinese bank (and does your bank provide you with a gold buying service?).
I am living in South-east Asia, and my bank allows me to purchase physical gold through my savings account. No KYC crap needed. And talking about China, it is not a 100% capitalist country. For example, people are free to trade in equities. But every now and then, the central government imposes restrictions, which makes conducting share trading very difficult.
