BEIJING - China's foreign trade volume rose 15.9 percent year-on-year to 22.52 trillion yuan ($3.39 trillion) in the first ten months of this year, official data showed Wednesday.

The trade surplus shrank 17.8 percent to 2.3 trillion yuan in the same period.

"China's imports and exports witnessed rapid growth in the first ten months," the GAC said in a statement.

Trade with traditional markets saw fast growth, with exports to the European Union, the United States and Japan up by 16.2 percent, 17.2 percent and 14.2 percent, respectively.

Both the trade volume and the share of private enterprises increased, as their combined volume rose 17.1 percent and accounted for 38.4 percent of the total, larger than the share for the same period of last year.
