North Korea implement border restrictions

North Korea implemented border restrictions with South Korea on 1 December 2008. Border patrols were increased, and two checkpoints were closed after North Korean officials accused South Korea of not abiding by its agreements. Two major projects between the two countries -- the cross-border railway and the joint industrial complex in Kaesong -- have been severely affected by the closure, with South Koreans being expelled from the country. The number of employees with more than 88 Korean companies operating in Kaesong has been cut back by more than a fifth.
