BEIJING, Nov. 7 (Xinhua) -- China's export growth slowed down in September due to the government's export tax rebate cuts since July 1, the China Customs said Wednesday.

The total export volume reached 112.5 billion U.S. dollars, an increase of 22.8 percent from September last year. Yet compared with the first eight months, growth slowed by 4.9 percentage points, said the Customs.

During the first nine months, exports also expanded at slower pace, standing at 878.1 billion U.S. dollars, up 27.1 percent on the same period last year.

Government policies to curb exports have been effective. Export goods on which tax rebates had been canceled saw their export volume decline 6.3 percent to 1.36 billion U.S. dollars in September.

Compared with the first eight months, processing trades slowed by 5.4 percentage points to hit 12.5 billion U.S. dollars, while ordinary trades slowed by 10.2 percentage points to stand at 24.6 billion U.S. dollars.
