A few hints from a top Chinese economist on moves with the yuan coming soon. The biggest little clue, one I have been watching for as a precursor to the Great Dollar Dump, is he is quoted as saying they may decide to peg to a basket of currencies. Translated that means start dumping bucks, which would lead to a global rout.(as I have been saying, when the US loses world reserve currency status, that's it, the party is over, that's all she wrote, etc, the empire goes away, it collapses) There's pressure on China to revalue higher, from all quarters around the globe, the big O harangued them a little bit about it..but they won't do that *until they are good and ready*, and right now they *aren't* good and ready, and are still scarfing up cheap-to-them natural resources all over, locking them in.
Their undervalued currency and massive manufacturing ability keeps letting them do this, it is a profitable loop for them, so they aren't in any hurry to change things. They can export and undercut most anyone, in return they get oodles of other nation's hard currency, which they turn around and use to get more raw resources via outright purchase or signed long term production contracts, etc. The other stuff they buy is advanced R&D, the means to keep doing what they have been doing. Anything at all to do with new tech, they get it, buy it, siphon it away, reverse engineer, whatever. They compound their own R&D budget immensely this way. Heck, they get foreign companies to put their own money up and come to China and build them even more factories!
