Unification Ministry to close humanitarian aid unit on North Korea SEOUL, May 4 (Yonhap) -- South Korea's Unification Ministry is set to close its bureau on humanitarian aid to North Korea as part of its restructuring, officials said Monday, a move that mirrors frozen political relations. The restructuring plan, when approved by a Cabinet meeting on Wednesday, will shut down the Humanitarian Cooperation Bureau established in late 1996, ministry officials said.
