The last seven South Korean workers who were staying at the Gaeseong Industrial Complex have returned home as the two Koreas resolved issues related to the South's outstanding payments to the North on Friday.

With their return, there are no South Koreans at the complex for the first time since the industrial park started operations nine years ago and the complex has in effect entered the state of a shutdown.

The South’s chairman of the Gaeseong Industrial District Management Committee Hong Yang-ho told reporters upon his arrival that the North was cooperative during the negotiations.

Hong said that he stressed to his North Korean counterparts that the operation of the inter-Korean factory park should be resumed swiftly. He said that the two Koreas will continue negotiation for the aim.

Earlier in the day, South Korea sent over two vehicles to North Korea to deliver the cash payment that the North demanded from the South on Friday afternoon. Hong refused to elaborate on the amount of the payment.

The government is said to be first using money from its budget to make the payments to North Korea and then will get paid back by the South Korean companies at a later time. Currently, the South Korean businesses at the inter-Korean complex are suffering from financial difficulties in light of the suspended operations.
