I have not yet read your links, but agree that the Yuan is likely to be as important if not more so than the dollar for world’s central banks reserves in no more than about five years. Partly this is because, things seem to be going much as I predicted back when GWB still had two years left as POTUS. I.e. I expect a run on the dollar on or before Halloween 2014, with its deep lose of dollar’s value and a depression in US and EU, to follow soon after the run, but not a depression in Asia – just a recession there and also in countries like Brazil, which will effectively have become “economic colonies” of Asia, especially China. If that dollar collapse has not occurred, within five years more, it will be to China’s long term economic advantage to destroy the dollar and when they are ready to do so they easily can. First they must convert more to a domestic based economy with exports to US and EU minor in volume compared to exports to other Asian nations (India and Mid East oil producers included) AND reduce the dollars they hold in their reserves to be significantly less (by spending them in long-term, (decades) paid-up-front contracts for the future delivery of energy, raw materials, and food stocks they will need to prosper for several decades into the future. All this they are now (and for several years) doing at an accelerating rate. They are also building a "blue water" navy with first aircraft carrier now at sea and many warships off East Africa and even one, for the first time ever, in the Med Sea to protect delivery on these contracts. I have told one easy way that China, the world’s largest producer of gold and also a major buyer of both gold and silver, with purchase rates about doubling annually now, can make the dollar collapse and central banks hold Yuan more than dollars: This is from: http://www.sciforums.com/showpost.php?p=2475063&postcount=55 ,made 9 Feb 2010. I did not bother to find the older post of this idea - it probably was not as clearly stated as this one is. Note also, this 15+ month old post effectively predicted the rapid rise in gold in part I have now made bold.
