After the global financial crisis，China is demanding the reform in international monetary system and pursuing the internationalization of its domestic currency，RMB. In this paper，I analyze the potential of RMB to become international currency. In order to estimate the public sector demand and private sector demand for RMB as an international currency，I conduct an analysis on the effects of GDP，trade volumes，price and exchange rate stability，and development of financial market，on the internationalization of currency by using panel data. The results of analysis show that it is expected to be unrealistic for RMB to be used as reserve currency that is the official demand for international currency. However，in this paper，I found the possibility that RMB could become international currency from the demands for RMB bonds. The demand comes from the surplus of Chinas trade balance. It is pretty much possible that once RMB becomes internationally used especially in Asia，it will with U.S. dollar and euro，form a tri-polar global currency system. With the political and regional reasons，RMB might be a representative currency in Asian region as people use more and more RMB instead of the dollar in trade settlement in the region.
