Last month 57 nations applied to become founding members of China’s newest creation: the Beijing-based Asian Infrastructure Investment Bank (AIIB). Ostensibly designed to help finance projects that sate Asia’s expanding appetite for infrastructure, the AIIB has left Washington struggling over how to respond.

Some oppose the move as undermining the U.S.-led economic order and using aid as a tool to advance China’s strategic agenda.
