The Cabinet decided on Tuesday to impose emergency import curbs on three agricultural products, starting Monday.

China is set to be worst affected by the curbs as it is a major exporter of the three products.

Tariffs on stone leek imports will jump from 3 percent to 256 percent when they exceed 5,383 tons. Shiitake will be taxed at 266 percent, up from 4.3 percent, on imports over 8,003 tons. Tariffs on rushes -- the straw used in tatami -- will rise to 106 percent, up from 6 percent, when imports exceed 7,949 tons.
