Chinese conglomerate Shougang entered the bidding to buy French-based parking space company Indigo, which operates in 17 countries and 500 cities, the French newspaper Les Echos reported, without citing any sources.

Indigo and its present owners, French private equity fund ArdianandPredica investment bank, wouldn't comment.

Indigo was put up for sale in February and is expected to fetch over 3 billion euros ($3.3 billion), Les Echos said.

Beijing-based Shougang is one of China's biggest steel companies but has a number of subsidiaries, including real estate concerns.
