China Eastern Airlines Corp., the country's third-biggest carrier, said Friday it was in talks with potential strategic investors, including Singapore Airlines Ltd.

China Eastern said its discussions with possible strategic partners were aimed at expanding opportunities for commercial cooperation.

It said it was considering taking on strategic investors when "timing matures." It didn't give a timetable or any other details.

Singapore Airlines said Thursday it was in discussions with the Chinese carrier but hasn't made any deal.

China's airlines are rapidly expanding their foreign ties, adding international routes and joining airline groups such as OneWorld and Star Alliance.
