China recently announced a new policy that seeks to rein in the de-velopment of processing trade in re-stricted commodities, in a bid to op-timize the country's exporting struc-ture, put strong curbs on the export of \"high-energy-consuming, high-polluting and resource-dependent\" products, and discourage the export of commodities with low added value and poor technology content, so as to gradually eliminate trade frictions, and promote trade balance to ease tension caused by the too wide trade surplus.
