- 1948 Aug 05 - "Request for Arrangement of Lands Between Korea and Japan," by Patriotic Old Men's Association
The Korean request asks for "Docksum" (Dokdo), Tsushima, and "Parang Island." Relayed to the US State Department on September 16, 1948. This group claimed the name "Docksum" came from the fact that the island was shaped like a "Korean pot." They also seemed to think that "Docksum" and Liancourt Rocks was another name for "Ulleungdo," which tells us they had little or no information Liancourt Rocks.

- 1950 Mar 30 - US State Dept. Report on "Korea's Recent Claim to the Island of Tsushima"
Report mentions, "it is obvious" that Korea's demands for Tsushima "...have not been based on a rational, legal analysis of the issue," but "...appear to be both a reflection of and a calculated appeal to the nationalism and the anti-Japanese feelings that prevail throughout the Republic."

- 1951 Jul 19 - Korea Asks for Treaty Ammendments, Korea Ambassador to Sec. of State
"My Government requests that the word "renounces" in Paragraph a, Article Number 2, should be replaced by "confirms that it renounced on August 9, 1945, all right, title, and claim to Korea and the islands which were part of Korea prior to its annexation by Japan, including the islands of Quelpart, Port Hamilton, Dagelet, Dokdo and Parangdo."
- 1951 Jul 19 - Memorandum of Conversation between Korean Ambassador Yang & Ambassador Dulles
"Mr. Dulles then inquired as to the location of the two islands, Dokdo and Parangdo. Mr. Han stated that these were two two small islands lying in the Sea of Japan, he believed in the general vicinity of Ulleungdo." [Parangdo was later discovered not to exist.]
Footnote 2, "In a note of August 10, to the Korean Ambassador, Mr. Rusk, on behalf of the Secretary of State, stated in part: 'The United States does not feel that the Treaty should adopt the theory that Japan's acceptance of the Potsdam Declaration on August 19, 1945 constituted a formal or final renunciation of sovereignty by Japan over the areas dealt with in the Declaration."
Footnote 3, "In the document cited in footnote 2 above, Mr. Rusk continued: "As regards the island of Dokdo . . . this normally uninhabited rock formation was according to our information never treated as part of Korea and, since about 1905, has been under the jurisdiction of the Oki Islands Branch Office of Shimane Prefecture of Japan. The island does not appear ever before to have been claimed by Korea." (Korea had in the meantime withdrawn the claim to Parangdo.)
- 1951 Aug 10 - Sec. of State Dean Rusk's letter to Korean Amb. You Chan Yang
"As regards the island of Dokdo, otherwise known as Takeshima or Liancourt Rocks, this normally uninhabited rock formation was according to our information never treated as part of Korea and, since about 1905, has been under the jurisdiction of the Oki Islands Branch Office of Shimane Prefecture of Japan. The island does not appear ever before to have been claimed by Korea."
- 1951 Sep 08 - San Francisco Peace Treaty
In Article 2a, Liancourt Rocks (Takeshima) is not included in the territory Japan is required to renounce claim to.
- 1952 Oct 03 - "Koreans on Liancourt Rocks," US Embassy in Tokyo to Dept. of State
"The rocks, which are fertile seal breeding grounds, were at one time part of the Kingdom of Korea. They were annexed together with the remaining territory of Korea when Japan extended its Empire over the former Korean State. However, during the course of this imperial control, the Japanese Government formally incorporated this territory into the metropolitan area of Japan and placed it administratively under the control of one of the Japanese prefectures. Therefore, when Japan agreed in Article II of the peace treaty to renounce "all right, title and claim to Korea, including the islands of Quelliat, Port Hamilton, and Dagelet," the drafters of the treaty did not include these islands within the area to be renounced. Japan has, and with reason, assumed that its sovereignty still extends over these islands. For obvious reasons, the Koreans have disputed this assumption."
"There therefore exists a fair chance that some time in the near future American bombs may cause loss of life or other incidents which will bring the Korean efforts to recapture these islands into more prominent play,...."
- 1954 - Report of the Van Fleet Mission to the Far East
"The Island of Dokto (otherwise called Liancourt and Take Shima) is in the Sea of Japan approximately midway between Korea and Honshu (131.80E, 36.20N). This Island is, in fact, only a group of barren, uninhabited rocks. When the Treaty of Peace with Japan was being drafted, the Republic of Korea asserted its claims to Dokto but the United States concluded that they remained under Japanese sovereignty and the Island was not included among the Islands that Japan released from its ownership under the Peace Treaty. The Republic of Korea has been confidentially informed of the United States position regarding the islands but our position has not been made public. Though the United States considers that the islands are Japanese territory, we have declined to interfere in the dispute. Our position has been that the dispute might properly be referred to the International Court of Justice and this suggestion has been informally conveyed to the Republic of Korea."
