China's hinterlands experienced relatively faster investment growth in the first half of this year, but analysts said these regions face greater downside pressure than eastern regions during the second half, precisely because their growth relied more on investment.

Fixed-asset investment excluding rural households in China increased 20.1 percent in the first half, the National Bureau of Statistics said Monday.

In central regions, the figure was 23.6 percent, while it was 22.7 percent in western regions and 18.7 in eastern regions.
