Beijing, Sep 13 (IANS): China's value-added industrial output expanded 6.1 percent year on year in August, the official data said on Sunday.

The growth rate was up slightly from six percent in July, Xinhua quoted the National Bureau of Statistics (NBS) as saying.

NBS statistician Jiang Yuan attributed the month-on-month increase to improving performance in key industrial sectors and accelerated growth in high-tech industries.

In August, high-tech manufacturing grew by 10.5 percent year on year and the growth rate was up 0.9 percentage points from July.

Despite the growth, industrial output still faces remarkable downward pressure due to flagging demand, Jiang said.

Year-on-year growth in the first eight months stood at 6.3 percent, the same growth level as the first seven months.

The figures showed that industrial output in China's central regions rose by 8.2 percent in August year on year, trailed by 7.7 percent in western areas and 6.2 percent in eastern regions.

Industrial output in the northeastern areas dropped 0.4 percent.

Manufacturing output rose 6.8 percent, mining output added four percent, while output of the electricity, heating, gas and water sectors increased 1.9 percent, the bureau said.
