CNH
From ACT Wiki
The currency of the People's Republic of China (PROC), when it is traded offshore.
The yuan is a heavily regulated currency but as part of the process of internationalising the currency the Chinese authorities have allowed a market in offshore deposits to develop.
The currency traded offshore is known as the renminbi CNH whereas the onshore currency is known as the renminbi CNY.
CNH is sometimes known as 'offshore CNY' or 'offshore RMB'.
Of these three codes, only 'CNY' is an official ISO currency code.
