The Chinese make it really hard for their citzens outside Hong Kong to buy gold. They only thing they are really allowed to own is property, which is why property speculation there dwarfs even what happened in the US in the run up to 2008. If the Chinese property market collapses, a lot of wealth will get destroyed and they will be even less able to buy gold.
India is in a better situation, both with their economy and demand for gold.
Thanks.
