The wholesale prices of Chinese cabbage and radish in South Korea have increased significantly in the past month, with cabbage prices rising by 160.7% and radish prices rising by 127.3%. This increase is likely due to the damage caused by Typhoon 'Kanun' and the heat wave the country is currently experiencing. Prices for other vegetables such as green onions and spinach have also increased by over 50% compared to a month ago.
