A noted long-time proponent of the tunnel project was South Korea's Sun Myung Moon (문선명), the late Korean founder and leader of the worldwide Unification Church. Moon proposed a "Great Asian Highway" as early as November 1981 at the 10th International Conference of the Unity of the Sciences and helped establish several related committees over the next three years.[22] Moon helped create the International Highway Construction Corporation (IHCC) in April 1982 to build the tunnel project and other transportation infrastructures, motivated by the project's potential for promoting international harmony and world peace.[22][23]
