After three consecutive months on the up, South Korea's producer prices remained flat in May.
The Bank of Korea says the production price index, a key barometer of future consumer inflation, stood at 103-point-seven in May almost unchanged from the previous month.
The central bank said industrial goods prices rose point-two-percent on rising global oil prices, but agricultural goods prices fell more than two percent on increasing supply.
The prices of electronics goods like semiconductors also rose slightly for the first time in seven months.
