I think it's related to the euro and the EU. Historically, the nations that have done this haven't done so well afterwards, however. Too little too late? I'm almost certain they don't trust us (who would?), and they sure don't trust France!! China's been doing some very interesting things with gold as well. Lots of rumors have been floating around that various nations have been trading with gold, instead of the commonly accepted US Dollar. Some say that's why certain nations have recently had 'problems, and leadership changes', because they wanted to use alternative currencies for doing business!!
I wouldn't put anything past our admin., nor the central banks of the world.
