China’s annual savings from the global commodities rout amount to US$460 billion, according to calculations by Kenneth Courtis, former Asia vice chairman at Goldman Sachs Group Inc. About US$320 billion of that is from cheaper oil, with the rest from other energy, metals, coal and agricultural commodities.SD-Agencies
