After more than two years of preparation, the China-initiated Asian Infrastructure Investment Bank, or AIIB, has been formally launched in Beijing.With 57 developed and developing nations as prospective founding members, the bank aims to provide financing for infrastructure construction across Asia.China, India and Russia are the three largest shareholders, taking stakes of around 30 percent, 8.5 percent, and 6.7 percent, respectively.So what opportunities and challenges will the AIIB bring? And what impact will China's slowing economy have on the bank's future prospects? PIK spoke with Dr. Hu Yuwei, Research fellow at the macro research department at Chongyang Institute for Financial Studies, Renmin University of China; Einar Tangen, Former Chairman of the State of Wisconsin's International Trade Council; and Winston Wong, Managing Director of Shipstone Group Limited.
