KUALA LUMPUR, Sept. 26 (Xinhua) -- Malaysia's producer price index (PPI), which measures the prices of goods at the factory gate, contracted 1.8 percent in August, as against negative growth of 2.3 percent in July, official data showed Tuesday.

The decline was contributed by the mining sector, which fell 3.8 percent, and the extraction of crude petroleum index, which decreased by 6.5 percent, the Department of Statistics Malaysia (DOSM) said in a statement.

At the same time, the manufacturing sector slipped 2.3 percent, affected by the drop in manufacture of coke and refined petroleum products and manufacture of food products indices.

The electricity and gas supply sector also recorded a decline of 0.1 percent.
