The Mount Kumgang Tourist Region is thought to be one way for the North Korean government to receive hard currency from abroad. Therefore, the official currency of the tour is neither the South Korean won nor the North Korean won, but the Chinese RMB and US dollar. Since 2003, food and services to South Korean tourists are provided by some North Koreans. But most of the staff in the hotels are Chinese citizens of Korean heritage with Korean language skills. The area is developed by Hyundai Asan, which plans to expand the site with a proper ski resort to complement the current sleigh course, and complete golf courses. Many plans for expansion, however, are in their earliest stages.
