Two representatives from the Chinese embassy in Paris have gone to Bordeaux and were due to meet with Le Foll later today, French officials said.
Racist insults were hurled during the attack yesterday in which a female student was seriously hurt in the face by a glass bottle that was thrown at her, Le Foll said. She was hospitalised and underwent surgery.
"It's an unspeakable act," Le Foll said, speaking at the inauguration of the Vinexpo in Bordeaux, one of the world's biggest wine fairs.
"It's the image of France which has been dented with these xenophobic attitudes," Le Foll added.

Interior Minister Manuel Valls has already denounced the "xenophobic" attack and vowed stern action against the perpetrators.

The students were attacked at their home in Hostens, a small village of 1,300 inhabitants about 50 kilometres south of Bordeaux in southwest France.
Concern has grown in China in recent months over the increasing number of thefts and attacks targeting Chinese tourists. In March, a group of 23 Chinese tourists were robbed in a restaurant shortly after they landed at Paris airport.
French winemakers have recently also sounded the alarm over an anti-dumping probe launched by Beijing into wine imports from the European Union, in an apparent retaliation act over Brussels' decision to slap tariffs on Chinese solar panel imports.
