Kim, meanwhile, said that the recent move by Pyongyang to change its tax codes for foreign companies operating at the Mount Kumgang on the east coast is a move in the "wrong" direction.
"It is advisable that the North respect earlier understandings reached between the two sides on the development and operation of the scenic resort," the spokesman said.
Seoul halted all tourist visits to the mountains after a North Korean guard shot and killed a South Korean female tourist in July 2008. Since then, the North has unilaterally nullified its deal with Hyundai Asan Corp. The company ran and built the resort from the late 1990s onwards.
