Haier Group, a Chinese fridge and washing-machine maker, is considering sparking a bidding war for Maytag, the US firm that makes Hoover cleaners.
Maytag is struggling to cut costs
The group, whose slogan is 'Haier and higher', issued a statement that it was "very interested in events surrounding Maytag", Reuters news agency reported.
Maytag agreed to a $1.13bn (£670m) offer from US investment group Ripplewood Holdings in May.
But the deal gave Maytag until 18 June to seek other buyers.
Several US private equity groups are also exploring a bid for Maytag, including Bain Capital, Blackstone and Kohlberg Kravis Roberts, the Financial Times reported.
Haier said it "has not yet made an decision" on whether to try to buy Maytag.
Maytag is a 102-year-old US company whose best-known brand internationally is the Hoover cleaner but - for US shoppers, at least - it has been linked with many iconic household products.
Haier invested $30m to open a plant in South Carolina
Iowa-based Maytag was founded as a farm-implements company, making its first washing machine in 1907. By the mid-1920s it was selling one in five of all washing machines bought in the US.
In the past year, falling profits have led to 1,100 job cuts as higher steel prices and competition from abroad hit sales.
State-owned Haier began in a bankrupt fridge factory in 1984, and now distributes its fridges in the US through Wal-Mart and Home Depot, concentrating on smaller 'beer-cooler' style fridges.
It was named China's most valuable brand by Forbes in 2004, and employs about 30,000 people.
Several Chinese firms are pushing to build international brands by buying struggling parts of big-name firms.
Lenovo bought IBM's PC operations, the most ambitious such deal so far, while mobile phone maker TCL bought Alcatel's mobile phone business, and Thomson's TV business.
Maytag's deal with Ripplewood includes a wipe-out of $975m of Maytag's debt and a break-up clause of $40m.
The prospect of a bidding war pushed up Maytag's shares on Wednesday.
