South Korea has stepped up border inspections of cabbage from China after vendors were found using formaldehyde to preserve the brassicas. The move follows a widespread crackdown by Beijing. Cabbage is a vital ingredient in kimchi, a staple of the Korean diet.

The Ministry of Food and Drug Safety announced strengthened checks at the border and promised further action if necessary. The announcement came after Chinese authorities uncovered the illegal preservative use. The development highlights the importance of food safety in the region and the tight supply chain between the two neighbors.
