Safmarine & Rennies Holdings, South Africa's largest shipping company, has confirmed one of its units is considering making a bid for Compagnie Generale Maritime (CGM).
Any decision hinges on a full review of the French state-owned shipper's finances.
The managing director of the company's Safmarine division in Cape Town, Tony Farr, said: 'No offer has been made at the moment.
'All that has happened is the French Government has indicated it is prepared to privatise CGM and has invited companies who are interested to consider making a bid.' The deadline for firm bids is October 3.
Any offer by Safmarine and its Belgian unit, Compagnie Maritime Belge, would be made through their jointly owned unit, Safmarine and CMBT Lines IV, Mr Farr said.
The unit, known as SCL, is based in Antwerp.
