In an April 2009 editorial, former Justice Ministers Daizō Nozawa of Japan and Kim Ki Chun of South Korea remarked on some of the similarities of the proposed Japan–Korea tunnel to the world's present longest undersea tunnel. The Channel Tunnel runs for 50.45 km linking the United Kingdom and France, and opened in May 1994: At 37.9 km, the tunnel has the longest undersea portion of any tunnel in the world.[36] The Japan–Korea tunnel faces technical issues and similarly the mistrust of two former adversaries created by centuries of conflict.
