I read that China's foreign minister Yang has meet with Hillary and Obama last week and Monday of this week. He returned to China on Tuesday. I do not know if the visit has anything to do with the drop in the dollar and gold and silver, but it may. When your biggest creditor visits, it usually means you pay down some debt or are getting a foreclosure notice. I think a huge drop in the metals occured a couple of years ago when the US and China higher ups met, and at that time people speculated that the US gave China something in return for China smashing the metals.
