Three international carriers have put in bids to buy a strategic stake in the ailing Malaysian carrier, Malaysia Airlines, according to a report published on Saturday by business weekly The Edge Malaysia. Malaysia’s government said on Tuesday that sovereign fund Khazanah Nasional Bhd, which owns Malaysia Airlines, has shortlisted four potential investors for the deal, after having invited initial proposals from a field of 20. Of the four short-listed, three of them are airlines - Qatar Airways, Japan Airlines and China Southern - The Edge reported citing sources. However, a Qatar Airways spokesman said that the airline was not among the bidders shortlisted. Khazanah is expected to decide on its preferred candidate soon, as Malaysia Airlines only has enough cash to sustain its operations till April next year, the report said. The Edge did not mention the identity of the fourth bidder or the value of the deal.<br/>
