Beijing apologised to Taiwan yesterday for Sanlu's tainted milk products and promised to step up inspections.
But mainland officials denied Taiwanese reports that a coffee creamer produced by another mainland company contained melamine.
'We feel deeply sorry for the hazards Sanlu formula might have brought to Taiwan consumers,' said State Council spokesman Li Weiyi .
He said officials had immediately alerted their Taiwanese counterparts after the mainland's quality watchdog reported that 1,000 bags of powdered milk sold by Sanlu to Taiwan in June were found to contain melamine.
The 21 other dairy companies whose products were contaminated did not sell any products to Taiwan.
Mr Li's remarks came after a large food and beverage supplier in Taiwan, King Car Industrial, recalled eight products containing cream imported from Duqing, a dairy company based in Shandong , on Sunday. The products, used as a coffee creamer and in instant chicken and corn soup, all tested positive for the chemical.
