Fiat on Monday issued a statement that it had not been approached by Great Wall about the Jeep brand. "Fiat confirmed that it has not been approached by Great Wall Motors in connection with the Jeep brand or any other matter relating to the business," the carmaker said. 

Takeover speculation reach all-time highs last week after a report claimed the company had received and rejected at least one offer from a Chinese automaker sending shares to highs but Dongfeng Motor Group DNFGF and Geely Automobile Holdings GELYF -- Zhejiang Geely's Hong Kong-listed unit - said there were not interested in the car maker.

Fiat has effectively been up for sale for at least the last two years. CEO Sergio Marchionne, who sees Fiat-Chrysler as lacking scale, has frequently been cited as a key driver behind the company's push to sell itself. Marchionne tried previously to have the company merge with General Motors GM, but he and Fiat were rebuffed by their larger rival.
