 In 2012, the International Hydrographic Organization (IHO), the intergovernmental organisation that maintains a publication listing the limits of ocean and sea areas around the world, abandoned its most recent of several attempts in the last 25 years to revise S-23.This was primarily because of the lack of agreement between the Koreas and Japan over the naming issue.An IHO consulting group is meant to report on the issue in 2020.
