BEIJING - China's exports accounted for 11.1 percent of world trade during the first three quarters of 2012, up 0.6 percentage point from the same period last year, the Ministry of Commerce said Wednesday.

Exports grew faster than those of other major economies during the first nine months despite global economic uncertainties, according to a ministry statement.

During the first ten months of 2012, exports of high-energy-consuming products and products which cause pollution during production, such as non-ferrous metals and steel, fell 7.3 percent year-on-year to $89.2 billion, the statement said.

The export volume of energy-intensive and high-polluting products slid 5 percent from one year earlier to 96.03 million tons during the ten-month period.

Meanwhile, China's capital goods exports accounted for 30.2 percent of the total exports during the January-October period, up 1.1 percentage points from 2007, according to the statement.

The ministry also said general trade grew while the weighting of processing trade dropped.

General trade amounted to $1.83 trillion during the first 11 months, accounting for 52.1 percent of the country's total imports and exports.

The processing trade accounted for 34.9 percent of the total imports and exports, down from 45.4 percent one year earlier, according to the statement.
