Chinese biscuits Hajuku and Koala and Julie's peanut crackers were found to contain more than the permitted limit of melamine.
'All three products contained more melamine than FDA standards allow,' Food and Drug Administration (FDA) secretary-general Pipat Yingseree said in a statement.
The products join Julie's cream cheese biscuits and Mali condensed milk which were withdrawn from sale in Thailand earlier this month.
China's prime minister said on Saturday his country would ensure its food exports meet international standards in future, in the wake of the melamine scandal.
'We will use our actions and high quality of our food products to win the trust and confidence of Chinese people and people around the world,' Mr Wen Jiabao told reporters in Beijing.
Four babies died of kidney failure and at least 53,000 children fell ill after consuming melamine-tainted milk powder and other dairy products in China this year, according to official figures. -- AFP
