President Obama has said he is "troubled" by the attacks on Google.
The Chinese government has denied that Google Gmail accounts were hacked into from school computers.
Shanghai Jiaotong University and Lanxiang Vocational School were named by US investigators as the likely origins of the hacks.
Foreign Ministry spokesperson Ma Zhaoxu branded the accusation "groundless".
He added that it was "irresponsible" to blame the government for the attacks, which led to Google threatening to pull out of China altogether.
Ma Zhaoxu was speaking at a press briefing.
Meanwhile Google and China are set to resume talks about Google's wish to operate an unfiltered internet search engine in the country according to the Wall Street Journal.
The Journal said that officials from both parties were due to meet again after the Chinese New Year celebrations in mid-February.
At the moment Google is still censoring search results in China, but it said in January that it would stop filtering results even if this action resulted in its Chinese operation being forced to close.
