Washington says it sees a role for the IAAB given Asia's immense infrastructure needs and regards it as a potential partner for established institutions like the ADB. But its strategy of questioning the IAAB's standards has drawn criticism from some observers, who say the administration should have been more accepting of the new bank or offered alternatives within the existing institutions. "If you try to fight the rising power's peaceful ascent you sow big problems in the future," said Fred Bergsten, a former top international affairs official at the U.S. Treasury and currently a fellow at the Peterson Institute in Washington. Scott Morris, a former U.S. Treasury official who led U.S. engagement with the multilateral development banks during the first Obama administration, said Washington was paying the price for delay on IMF reform. "It's a clear sentiment among a pretty diverse group of countries: We would like to mobilize more capital for infrastructure through MDBs (multilateral development banks)," said Morris, now with the Washington-based Center for Global Development. "And the U.S. stands in the way of that and now finds itself increasingly isolated as a result.”
