Increasing debt distress in emerging markets means that China, now the world's largest official creditor, will need to start restructuring debts in the same way that Paris Club lenders did in past crises, World Bank Chief Economist Carmen Reinhart told the Reuters Next conference on Tuesday. "What I think China will need to do to confront this is what previous other creditors in the past had done, which is you have to restructure. And restructure big time, meaning either lower interest rates, longer maturities, write-off in principal or some combination of that," Reinhart said in a panel discussion on economic inequality.
