Issued by China in 1995, this commemorative 20-fen stamp marks the inauguration of the China–Korea Submarine Optical Fiber Cable System, a major technological milestone in regional communications. The design features a map showing the cable route across the Yellow Sea, linking the two nations, along with a detailed illustration of the fiber-optic cable itself. The layout highlights both geographic connection and engineering precision, reflecting China’s rapid modernization in telecommunications during the 1990s. A desirable thematic item for collectors of technology, infrastructure, and Asian cooperation issues.
