Li Xiaojia, chief executive of the Hong Kong Stock Exchange, once said that in the future, three things will ensure the uniqueness of Hong Kong. The first is to help in the realization of the global allocation of Chinese national wealth. The second is to help Chinese and foreign investors to manage onshore financial risks in the offshore. The third is to help China realizing the international pricing of commodities and currencies and providing the stage for China's funds to be priced overseas. Hong Kong can act as an international pricing center for RMB and become the "home field" of mainland investors and the "visiting field" of foreign investors.
