Troubled Ssangyong has said it has closed its main factory south of Seoul in response to an ongoing labour strike.

The automaker's labour union launched a full strike last week in protest against the company's job-cut plan.

Ssangyong, which has been under US-style bankruptcy protection since February, said last month it will cut 2,646 jobs, or 36 percent of its total workforce.

In response to the work stoppage, Ssangyong said it closed the Pyeongtaek factory, about 70 km south of Seoul.

The Korea Times reported that negotiations underway between the labour union and the management have made little headway in narrowing differences.

In May, the Seoul Central District Court said Ssangyong is worth saving rather than liquidating, but warned it could still liquidate the ailing carmaker if it fails to make the job cuts as promised.
