General Motors' Korean offshoot is set to buy a stake in a Polish car maker.

GM Daewoo Automotive & Technology said at the weekend it would buy a 40% stake in car maker FSO from the Polish government for 238.7bn won ($US254.5m), according to a Reuters report.

The automaker would become a joint venture, tentatively named GM FSO, the report added.

The deal is part of GM Daewoo's efforts to expand in Europe, but the South Korea-based company is unlikely to buy the remainder 60% in FSO, a GM Daewoo spokesman told the news agency.

Reuters noted that FSO and other east Europe Daewoo assemblers were left out of the original General Motors and partners deal that took a majority stake in some assets of failed Daewoo Motor in 2002, creating GM Daewoo.

GM Daewoo president Michael Grimaldi last April told Reuters that the company was in talks with Romania to buy Daewoo Motor's plant in the country.
