China Currency Overview
The two yuan.
@ BBC: The "Renminbi" is the official name of the currency introduced by the Communist People's Republic of China at the time of its foundation in 1949. It means "the people's currency". "Yuan" is the name of a unit of the renminbi currency. An analogy can be drawn with "pound sterling" (the official name of the British currency) and "pound" - a denomination of the pound sterling. Something may cost £1 or £10. It would not be correct to say that it cost 10 sterling.
China has another set of codes for the FX markets.
CNY = onshore
CNH = offshore
The CNH doesn’t fluctuate within a tight band like CNY, and it is perceived to be free of China’s government control due to the trading taking place offshore in Hong Kong.
