Cos China doesn't produce anything, no way Jose.
DERP.
the Yuan is, under chinese law, INVALID outside the PRC, hong kong and macau.
there is no Yaun international currency exchange
if you take a trip to china and come back with a fist full of Yuan, you cant convert it to real monies without losing your shirt to a rigged exchange rate (Us dollar or euro to Yaun, super easy, Yuan to aything else: harder than algebra, and the rate is rock bottom low) the Yuan is like Disney Dollars. it's only valid in their country, and selling it back for real monies is a losing proposition every fucking time
china has set the Yuan up to be a siphon for international currencies. foreign money can go in, but the Yuan has almost no value outside the PRC.
read this shit:
"It is not generally possible to obtain Chinese currency outside of China. There is no limit to the amount of non-Chinese currency you may bring in to China, although you are supposed to declare larger amounts (over US$ 5,000). It is relatively simple to change money into RMB in branches of the Bank of China. Larger hotels also have currency exchange, but some will only cater for guests. There is no competition in exchange rates. The standard rate applies everywhere. It
is illegal (and risky!) to exchange money outside of the banking system.
NOTE Banks will only accept notes in perfect condition. The smallest tear or defacement will result in your cash being refused. UK visitors should note that Scottish or Northern Ireland bank notes are NOT accepted. Major travellers' cheques are accepted.
More problematic is changing RMB back to foreign currency. The standard contract stipulates that a certain percentage of your salary can be exchanged. This is normally set at 30%, but can be higher. However, contracts aside, it can prove difficult to make the actual exchange. This
should change with China's entry to WTO.
Chinese law states that no more than ¥20,000 in RMB may be taken out of the country. That said, I have never been asked to show my money on exit. RMB cannot easily be exchanged in the US or Europe (apart from Switzerland!). It is possible to exchange RMB in Exchange Offices in Australia (not the banks) but only at an extremely poor rate. It is possible to change RMB in Hong Kong and in Bangkok."
