B shares were limited to foreign investment until 19 February 2001, when the
China Securities Regulatory Commission began permitting the exchange of B shares via the secondary market to domestic citizens.[2] This was widely seen as a landmark event to the integration of Chinese stock markets.[3]
Currency
The face values of B shares are set in Renminbi. In Shanghai, B shares are traded in
