The relationship between the two Koreas is plunging towards rock bottom as their joint industrial complex -- the last bastion of their reconciliation -- has turned into a military zone with all its communication channels severed.



Seoul and Pyongyang exchanged barbs, shifting the blame to one another for the closure of the factory park in the North’s border city of Gaeseong. They are showing no signs of compromising to ease rising military tensions on the peninsula.



On Thursday, Pyongyang expelled all 280 South Korean workers from Gaeseong, effectively closing the complex that opened 12 years ago following the 2000 inter-Korean summit. It also froze all South Korean assets in the complex and declared it as a military off-limit zone.



This move came a day after Seoul decided to pull out of the complex as part of punitive measures following Pyongyang’s recent nuclear and missile tests.



Seoul’s Unification Minister Hong Yong-pyo rebuked Pyongyang for freezing South Korean properties, expressing displeasure over the communist regime’s “wrongful” act.



“The South Korean government thinks that it is very regrettable for North Korea to have done such a wrongful act, and we would like to make it clear that the North should take all responsibility for things to come in the future,” he told a press conference.



He also issued a “grave warning” against Pyongyang’s decision to freeze South Korean assets in the Gaeseong complex and defended Seoul’s decision to pull out as a “difficult one (made) for national security and people’s safety.”



“Our citizens’ precious properties should never be harmed,” Hong said.



The South has made investments into the complex, estimated to be worth some 1.02 trillion won ($841 million). A total of 124 South Korean companies hired some 55,000 North Koreans to produce some 60 billion won worth of products every month.
