Liancourt Rocks dispute Liancourt Rocks dispute The Liancourt Rocks dispute is a territorial dispute between South Korea and Japan. Both countries claim sovereignty over the Liancourt Rocks, a group of small islets in the Sea of Japan which are referred to as "Dokdo" () in Korean and in Japanese. North Korea also claims sovereignty of the islands. The Liancourt Rocks have been administered by South Korea since 1954 by the Korea Coast Guard. This action was taken after the United States stated in the Rusk documents that the Japanese claim to the Liancourt Rocks would not be renounced in their peace treaty with
Sukjong of Joseon in China to define the national borders between the two countries at the Yalu and Tumen Rivers. The Japanese government recognized Ulleung Island as Joseon's territory in 1696 (Korean Government insists that Liancourt Rocks was also recognized. But Japanese Government insists that Liancourt Rocks was not recognized as Joseon's territory). Sukjong's reign also saw agricultural development of far provinces and increased cultural activities including publications. He died after reigning for 46 years in 1720 at age 60. He was buried in Myeongreung (명릉) in Gyeonggi province, Goyang City inside Western Five Royal Graves (西五陵 서오릉 "seooreung"). Sukjong of Joseon Sukjong
