The Chinese Renminbi (RMB), often referred to as the Chinese Yuan is the official currency in China and an unofficial currency of some of its neighbouring countries. The currency is issued by the Central Bank of China and came into circulation in its current form back in 1948. The RMB was until 2005 pegged to the US-Dollar but is nowadays a free floating currency. It's one of the largest currencies in the world and an appreciated currency on several online gambling casino sites.
