South Korea's export prices last month were up compared to the month before, but so were import prices.
The Bank of Korea says the export price index increased by 1 percent from July to almost 113.
This was the ninth straight month of gains, although the speed of the increase slowed from the previous month.
The increase in export prices was driven by higher prices of industrial products like chemical products.
Import prices rose point-6 percent on-month mainly on higher intermediate goods prices, including primary metal products.
