A quarter of imported children's milk bottles and teats failed a recent random quality test in southeast China, Xinhua news agency said on Friday.
"Do you think foreign brands mean high quality?" the report asked, before detailing the findings of the survey in coastal Fujian province.
The results "should attract the highest attention from children and their parents", it added.
"These products are not up to standard for safety and hygiene reasons, and may harm children's safety and health," the report added.
The products came from Japan, Germany, Britain, Singapore, Thailand, Indonesia, Taiwan and Hong Kong, Xinhua said, adding "most of them were brand-name goods".
China blamed the media on Thursday for stoking fears about the safety of the nation's food and drugs, but senior officials acknowledged that it was not realistic to expect a 100 percent quality guarantee.
