@morten_skaaning @WashingtonIrving In many cases, they already have. China doesn't want to take rubles, in most cases. And why should they, when they can basically demand payment in gold, in many cases... oftentimes at a premium.
That's right... they are using sanction-evading ways to trade Russian gold, for less than the price of gold. Which is basically the same thing as free money, IF you can find a legitimate buyer.
Of course, this tends to deflate the actual value of gold.
