BEIJING - Hainan Airlines, China's fourth-largest carrier, is still interested in buying a stake in US film studio Metro-Goldwyn-Mayer (MGM) after a failed bid last year, a source familiar with the matter said.

The source said the carrier intended to join hands with a foreign company to swap shares with MGM last year when the studio was bringing in strategic investors for restructuring.

The deal wasn't made because the two sides couldn't reach an agreement on the price.
