US goverment has commercials running in every state that say: " your GOLD for cash we will buy your old, broken jewlrey" The US Goverment is desperate to collect as much of the Gold from not so smart Americans . The US has NO GOLD to back the paper Dollar. For it is truly worthless. They just keep printing MORE and MORE paper.... For this is the truth! Most Americans are Keepining their GOLD. CA. where the Gold Mines are you need to see if they are even open. You never hear of any Gold miners EVER!! For this is true.
practically speaking, every country manipulate their currencies, at least under some occasions.
It's not fair to judge China's foreign currency policies,only based on some US politicians' view and the exchange rate against US dollar. We should take the other cross exchange rates into the considerations.
