"China is greatly shocked by the terrorist attacks that has caused massive casualties. China strongly condemns these attacks," foreign ministry spokesman Hong Lei said.
"China expresses deep condolences to the victims and extends sincere sympathies to the families of the dead and injured," Hong said in a statement.
Describing terrorism as a common challenge facing mankind, Hong said China firmly supports France to maintain national security and stability and combat terrorism.
The attacks, whose motive was not immediately clear, came less than a year after jihadist gunmen killed 17 people in attacks on Charlie Hebdo magazine and a Jewish supermarket.
A state of emergency has been declared by President Francois Hollande. He also announced that he was closing the country's border.
