The ISO code for renminbi (which may also be used for the yuan) is CNY (an abbreviation for "Chinese yuan"), or also CNH when traded in off-shore markets such as Hong Kong. The currency is often abbreviated RMB, or indicated by the yuan sign ¥. The latter may be written CN¥ to distinguish it from other currencies with the same symbol (such as the Japanese yen). In Chinese texts the currency may also be indicated with the Chinese character for the yuan, 圆 (or 元 informally). The renminbi is legal tender in mainland China, but not in Hong Kong or Macau. Renminbi is sometimes accepted in Hong Kong and Macau, and are easily exchanged in the two territories, with banks in Hong Kong allowing people to maintain accounts in RMB. The currency is issued by the People's Bank of China, the monetary authority of China.
