HEFEI - What? Already 160 Carrefour stores in that city? The Paris-based supermarket giant was left in wide-eyed astonishment when it conducted market research in Fuyang city, East China's Anhui province.

Carrefour SA has filed a lawsuit against Anhui Jiale Supermarket Chain Co Ltd and its subsidiaries in Fuyang, claiming they violated the rule of fair competition and infringed upon the Carrefour trademark.

The local supermarket chain was accused of illegally using the logo "Jialefu," the Chinese version of "Carrefour," in their company name and business activities.
