South Korea on Monday made a "final" formal offer of talks with North Korea over the fate of a shuttered joint industrial zone, officials said.
The "final" talks offer comes after six rounds of talks between the two in recent weeks aimed at reopening the shuttered joint industrial zone produced little progress.
The joint factory located in Kaesong city of North Korea at the border was forced to shut down amid high-tensions over the Korean peninsula following a series of missile and nuclear tests by the Pyongyang government.
"We once again urge North Korea to make a right choice for the normalisation of Kaesong and inter-Korean relations," said unification ministry spokesman, Kim Hyung-Suk, while speaking to the reporters.
The South Korean unification ministry added that the talks offer was sent through the border truce village of Panmunjom.
While making the talks offer, South Korea made it clear that the North was responsible for the sudden closure of the joint industrial factory.
"Pyongyang should accept responsibility for the unilateral closure of the facility and should make sure that such an action will not happen again," the Unification Minister Ryoo Kihl-Jae said.
Pyongyang has repeatedly denied the accusation saying its hand was forced by Seoul's intimidation, especially, the South Korea-U.S. joint military exercise held at the border of the two Koreas.
In recent months, the United Nations and a number of U.S. allies including South Korea and Japan have urged the Pyongyang government to drop its nuclear ambitions and engage in disarmament talks.
North Korea has constantly denied the calls, saying nuclear weapons are its only "treasure."
