This paper assesses whether the establishment of the Asian Infrastructure Investment Bank (AIIB) signals China's reformist intention in the area of international development. I use both descriptive and inferential statistics to compare power distribution in the World Bank, the Asian Development Bank (ADB), and the AIIB, and the composition of the AIIB membership. Evidence shows that there is no obvious structural difference in voting power among the three banks. The major difference between them is that China is the most powerful state in the AIIB. For the time being at least, the AIIB does not signal Beijing's intention to reform the current system. Instead the bank seems to be an instrument that China can use to compete with established international financial institutions. However, Beijing may be faced with several challenges.
