The students were attacked in the early hours yesterday in France's wine-producing region of Bordeaux, France's interior ministry said, describing the violence as an act of xenophobia.
Two of the three alleged attackers have been detained and are now in police custody, while a female student was seriously hurt in the face by a glass bottle which was thrown at her.
The attack was widely criticised on China's most popular social networking service, Sina Weibo, which is similar to Twitter.
"This is too far for the French people. My impression of France used to be quite good, but now its damaged," said another.

One of the victims was the daughter of a retired senior government official, the head of the student's school said.
Chinese media carried report of the attacks today, but did not mention the victim's political connection.
The topic of politicians sending their children abroad to study provokes widespread resentment in China and is rarely-discussed by the country's tightly controlled press, which is rarely allowed to discuss the family life of senior officials.
Others reading English-language reports turned their anger on the students. "Even foreigners can't bear with the migration of corrupted officials and are punishing them abroad. This is karma," another user said.
"That a random violent crime abroad has a government official's children involved again proves their are no clean officials in China," another wrote.
