( CNN ) -- After two days of talks , North and South Korea are inching towards restarting operations at the joint Kaesong Industrial Park . The manufacturing complex run by North and South Korea , sits just north of the DMZ that separates the two countries . It housed operations of more than 120 South Korean companies and employed 53,000 Northern workers , before souring relations halted operations this spring . The last remaining South Korean workers left the facilities in May , although work had been winding down amid tensions . Workers left with belongings strapped onto their cars . For the first time since then , South Korean business personnel will be permitted to visit the complex and inspect their equipment Wednesday . On the same day , the two nations will hold another round of talks aimed at preventing such an outage and normalizing operations at Kaesong . South Korean businesses will be permitted to take their products as well as raw materials out of Kaesong . The North agreed to ensure safe passage for South Korean personnel , according to KCNA , North Korea 's state-news agency and a statement from South Korea 's Ministry of Unification . In its nine years of existence , the Kaesong Industrial Complex has served as a bellwether of North-South ties and the remaining vestige from the `` Sunshine Policy , '' when the two Koreas had an unprecedented level of engagement ( 1998-2008 ) . North Korea has barred South Korean workers from entering the complex before in 2009 and 2009 . `` We clearly pointed out that the recurrence of sudden stoppage by the DPRK 's unilateral action must not happen , '' said Kim Hyung-suk , spokesperson for the Ministry of Unification . `` It also implies the expression of the government 's will to normalize the Kaesong Industrial zone constructively in the future . '' Kaesong is considered to be an important source of hard currency for Kim Jong Un 's government as more than hundreds of millions of dollars ' worth of goods are produced each year . Opinion remains divided on the potential restart for Kaesong . An editorial in the Wall Street Journal said that South Korea 's president , Park Geun-hye is `` repeating one of the worst mistakes of the misbegotten 'Sunshine Policy ' of a decade ago . '' It warned that , `` Temporary closures of Kaesong are part of the Kims ' toolbox . Shutting the complex down for good ca n't solve the problem entirely , but it should diminish their leverage and hasten the regime 's eventual collapse . '' Another editorial published during weekend in South Korea 's JoongAng Daily , urged keeping Kaesong , saying that the venture must be kept alive to `` solve other inter-Korean problems . '' Meanwhile , North Korea marked the 19th anniversary of the death of its founder , Kim Il Sung , Monday . KCNA reported that Kim visited the hall where his grandfather lies as well as his father , Kim Jong Il at Kumsusan Palace of the Sun . In recent weeks , North-South relations appear to have thawed . North Korea agreed to high-level talks with the South in June , though those talks were called off at the eleventh hour after disagreements about the level of the delegates who would represent each side . This weekend 's talks occurred after North Korea restored a communication hotline with the South , which had been cut off repeatedly over the past four months .
