Korea said Thursday it plans to increase the supply of key foodstuff by a record amount in a bid to help curb inflation ahead of the Chuseok fall harvest holiday slated for next month.

The government plans to supply a combined 230,000 tons of 20 items of farm, livestock and fisheries products for three weeks in the runup to the extended Chuseok holiday set for Sept. 9-12, the finance ministry said.

The government aims to lower the average prices of the 20 items by 7.1 percent from current levels.

Demand for vegetables, fruits, eggs and other foodstuff usually rises in Korea ahead of the Lunar New Year and Chuseok holidays as people prepare holiday meals for family gatherings.
