The industrial park and the tour program were two symbolic cross-border projects before they came to a halt in 2016 and 2008, respectively, amid worsening relations between the two Koreas.

Kim and South Korean President Moon Jae-in agreed in their September summit to "normalize" them as soon as "conditions are met."

The agreement, however, has not yet been carried out due to the multiple sanctions on Pyongyang that ban investment in and economic projects with the reclusive country. 

On Tuesday night, Unification Minister Cho Myoung-gyon told a local broadcasting program that it is hard to push for the resumption of the two suspended projects without considering sanctions.

He reaffirmed Seoul's will to get them back on line first when inter-Korean relations further improve and North Korea gives up its nuclear weapons program.

With regard to a possible visit to the Kaesong complex by businesspeople who once operated factories in the industrial park, the spokesman said that their trip would not violate sanctions but the government stance on it would be determined based on consultations among relevant ministries and agencies going forward.

With inter-Korean relations warming since early last year, the two Koreas have pushed to bolster cooperation in diverse areas, but most major cross-border projects cannot proceed without sanctions exemptions from the United Nations.

Seoul had to receive a sanctions waiver from the UN to carry out a planned joint inspection of railways in the North late last year as part of efforts to reconnect the rail systems of the two Koreas as agreed to by their leaders in April.

Sanctions are regarded as a major hindrance to the North's push for economic development, an objective that was highly emphasized by the leader during his address on Tuesday. Kim warned that he would take a "new way" if the US continues its pressure and sanctions while not making good on its promises with the North during their June summit. (Yonhap)
