South Korea’s Fair Trade Commission imposed fines of 331.1 billion won on Baemin’s operator and 300.8 billion won on Coupang over demands that restaurants match or beat rival delivery apps’ prices and terms. The regulator said the practices restricted competition in a market where the two platforms together account for about 93 percent of usage, while restaurants faced pressure because leaving the platforms could sharply reduce sales.

Both companies rejected the findings and said they would review the final decision before considering legal action.
