US-based Mead Johnson, which makes the Enfamil formula, said it would pay $33m in penalties
China has levied a record fine of 670m yuan ($109m; £71m) on six foreign producers of infant formula for price-fixing, state media say.
The six companies involved were Mead Johnson, Biostime, Dumex, Abbot, Friesland and Fonterra, it said.
The move follows an antitrust and anti-competition probe by authorities.
Consumers in China are willing to pay more for foreign brands after six children died from drinking tainted milk produced locally in 2008.
The fines, announced by China's top economic planner, the National Development and Reform Commission, coincide with a separate pricing investigation into the pharmaceutical industry.
US-based Mead Johnson, which makes the Enfamil formula, said it would pay $33m in penalties. Biostime, based in Hong Kong, said its local unit was fined $26.3m.
Neither company gave details of conduct that had caused the fines to be imposed.
