Officials from North and South Korea are meeting for the third time this month to discuss how to restart a stalled inter-Korean factory park which was a key symbol of co-operation between the countries.
Seoul's Unification Ministry said the talks are taking place in the North Korean border town of Kaesong where the factory complex is located.
In their previous talks, the countries agreed on a desire to revive the complex but could not agree on how to do so.
Operations at the Kaesong complex were suspended in April when tension ran high in the wake of a nuclear test by North Korea in February.
The park opened in 2004 during a period of rapprochement between the Koreas. It blends South Korean capital and management skills with cheap North Korean labour.
