Never one to forgive and forget, North Korea has kept South Koreans out of Kaesong since July 1, insisting that it will work with Lotte Tours instead of its long-time original partner Hyundai Asan on a Kaesong tourism project. The Unification Ministry said Friday the North has been asking the government to change its Kaesong tourism project partner from Hyundai Asan to Lotte Tours since May. Seoul demurred, saying it cannot be a party to contract violation, and Pyongyang has to deal directly with Hyundai Asan. On June 22, the North avenged itself with a letter to Unification Minister Lee Jeong-sook notifying him that South Koreans are now barred from the North Korean border city.
