North Korea said international investors are showing strong interest in the co-development of its Wonsan-Mount Kumgang International Tourist Zone, seven years after South Korea tours to the region were suspended, UPI reported. Oh Ung Kil, North Korea vice chairman of the tourist zone, said North Korea is working with several Asian and European companies on the region's development, Yonhap reported. Pyongyang's state media outlet KCNA said during a recent investment seminar several contracts were finalized with foreign firms in the design planning, IT and construction sectors. Firms offering food and drink, transportation and lodging services also were mentioned as investors – signs that pointed to direct foreign involvement in reviving tourism in the scenic mountain region.
