The government will selectively allow South Korean business professionals to visit North Korea for checks on their past investments there, an official said Wednesday, amid a prolonged suspension of trade with the communist state following its deadly attack on a Southern naval ship last year. For business purposes, these individuals will also be allowed to meet their North Korean counterparts in a third nation outside the Korean Peninsula, the Unification Ministry official said, on the condition of anonymity. The ministry handles inter-Korean relations, which have seriously frayed following the torpedoing of the warship Cheonan in March last year.
