Sustainability need of the hour, says Dollar

China faces a different and bigger challenge now to sustain its growth, said David Dollar, who is spending his final day today as China director of World Bank.

"The Chinese government faces its biggest challenge ever to put domestic consumption back on a sustainable path," Dollar told China Daily in an exclusive interview before he takes up his next job as the Economic and Financial Emissary of the US Embassy in Beijing.

Five years back when David Dollar started his WB stint in Beijing, he felt environmental problems were the biggest challenge for the nation. "I thought what challenged China most then was environmental degradation."
