Yes but do they plan to actually start buying or are they just mouthing off to get the US off their back about revaluing their currency (or imposing a 23% import tariff on Chinese goods)?
China holds so many US dollar reserves that it would be tough to dump even a fraction of them on the open market without seriously weakening the dollar and greatly devaluing the remainder.
True, but they don't have to buy any more dollars either, just by holding the current position and buying gold to meet the dollar loss of value would be enough given the huge sums here?
