Chinese Foreign Ministry spokesman, Qin Gang, said the government had cracked down on melamine contamination and hoped the US could take "an objective and calm" approach, according to Reuters.
Last week the US Food and Drug Administration expanded its import controls on Chinese dairy products, and food and feed products manufactured in China that contain dairy ingredients.
It followed the deaths of four infants in China linked to consuming baby milk contaminated with melamine.
However, Qin, who was quoted by Reuters, said: "We feel deep regret that the US insists on unilaterally taking these steps.
"We hope the US can pay great attention to Chinese concerns, as these steps will have an effect on bilateral trade.
“We hope the U.S. ... can lift the ban as soon as possible.”
