I would personally add Russia to the mix. The reason is simple: both China and Russia are sources of capital flux, where those with means are funneling funds outside their respective countries.

Because there are, or have been, capital controls in place, those who move money out of their countries are willing to pay a premium for it. Funnily enough, there is a name for the phenomenon where actors with money are willing to pay exorbitant transaction costs in order to move funds from one jurisdictional domain to another.
