Asian economies, particularly Japan, must immediately implement necessary structural reforms to strengthen the nascent recovery in the region, an international panel of academic, political and business leaders warned Wednesday.

In a symposium on Asian economies that was organized by the Japan External Trade Organization, Asian, European and U.S. speakers hammered home the point that Asian economies -- while recovering or on the path to recovery -- are still vulnerable.

Former Philippine President Fidel Ramos said the regional recovery "does not give us enough reasons to celebrate," because numerous fundamental reforms have not yet been carried out.
