South Korea will merge Korea National Oil Corp. and Korea Gas Corp., combine five Korea Electric Power Corp. units, liquidate Korea Coal Corp. and amalgamate four regional port authorities. The government said the restructuring will consolidate institutions with overlapping functions, integrate subsidiaries and smaller public entities, and improve infrastructure management while reallocating technology and personnel. The measures form part of a broader effort to make public institutions more competitive as the country responds to technological shifts, demographic changes and persistent, complex economic risks. South Korea is also under pressure to expand and modernize its power infrastructure to meet rising electricity demand from artificial intelligence and semiconductor factories.
