(Updates adding response from Tesco.) By P.R. Venkat and Costas Paris Of DOW JONES NEWSWIRES SINGAPORE (Dow Jones)--Leading supermarket chains are interested in the assets of French hypermarket Carrefour SA (CA.FR) in Singapore, Thailand and Malaysia, two people with direct knowledge of the deal said Tuesday. "It's the big boys that are interested. Big C Supercenter PCL (BIGC.TH) and Tesco PLC (TSCO.LN) for the Thai assets; Tesco, Dairy Farm International Holdings Ltd.(D01.SG) and Japanese supermarkets for the Malaysia stores, and Tesco for Singapore," one of those people told Dow Jones Newswires. A second person said if a single buyer emerges for all three countries "the deal will probably be wrapped up this year. If not, it could take a bit longer." A third person said Monday that Carrefour was in the early stages of selling its stores in Thailand, Singapore and Malaysia and that if the sale goes through it could fetch the French retail giant up to US$1 billion. Carrefour, Tesco and Dairy Farm all declined to comment. Big C didn't immediately respond for comment, while Japanese supermarket AEON Co. Ltd (8267.TO)--which has bought the Japan assets of Carrefour--couldn't be immediately reached for comment. An official from AEON's Malaysia unit declined to comment. Carrefour Chief Executive Lars Olofsson in May said he was open to offers for the company's operations in markets where it isn't in the top two. Analysts have cited Thailand, Malaysia and Singapore as likely candidates. Under Olofsson's direction, Carrefour has focused efforts on its key European markets of France, Spain, Italy and Belgium, where weak consumption is hurting business. France alone accounts for nearly half of the company's annual revenue. -By P.R.
