North Korea has notified South Korea that it will expel all but 16 South Korean workers from the North’s Mount Geumgang resort.

According to the Unification Ministry in Seoul, the president of the North's Guidance Bureau for Comprehensive Development of Scenic Spots visited the Hyundai Asan office in the resort Friday and demanded that the workers leave by 10 a.m. Monday.

The sixteen who will be allowed to remain include 12 Hyundai Asan workers and four staffers at Emerson Pacific, which owns a golf course at the mountain resort.

Currently, 70 South Korean workers are stationed at Geumgang who are employed by Hyundai Asan and other private companies.

Prior to Friday, North Korea seized properties within the resort owned by the South Korean government and froze facilities owned by private companies.

But it has yet to freeze Hyundai Asan’s Geumgang office, its staff accommodations or a power plant that provides electricity to Geumgang facilities.

Hyundai Asan is the South Korean firm in charge of tour programs to North Korea.
