The nations with trade surpluses are starting to gradually move away from the influence of the Western-centric governing bodies, principally, the dollar can't take much of that. And because the trade-surplus club are obviously industry/manufacturers, they want/need to keep their currency cheap, or they have fewer markets to export the goods to .
It's a negative feedback loop, the race to the bottom, and the ultimate consequences are for the dollar and the US economy. Japan, Saudi Arabia, China, and the whole EU all have long way to fall also, but the US is more propped up with more unpayable debt than anyone else. So, 2016, whenever, one of the above suffers a serious loss in confidence in ability to repay sovereign debt, and then they'll all suffer problems and/or defaults. Time to "bail-in" the boat, apparently... lol
