What Korea needs to protest on Japanese assertions of sovereignty over Dokdo is (i) for removing the connivance on Japan's claims, (ii) for acquiring the effective control over Dokdo of Korea, and (iii) for reinforcing the relative ground claims into the dominant or absolute ground claims.
The protest subject on the basis of international law is a nation or an international organization. Therefore, the protest subject against Japan is not Kyongsangbuk-do⋅Ulleung-gun⋅ The Grand National Party⋅KBS⋅Dongailbo Northeast Asian History Foundation⋅Dokdo Center, but the nation, "the Republic of Korea(ROK)".
leader⋅the minister of Foreign Affairs⋅delegates. So, the national authority of the ROK on the protest against Japan is not the national assembly speaker⋅the minister of Education, Science and Technology⋅the president of Northeast Asian History Foundation⋅the president of Dokdo Institutethe⋅the chairman of Dokdo Center, but the president⋅ the minister of Foreign Affairs and Trade⋅the embassador of Korea in Japan.
The protest form on international law should be done by the diplomatic document through the diplomatic channel. The protest against Japan is not effective as protests through a news conference, a radio broadcast, TV, an resolution of the international conference, a statement of the seminar.
The protest content on international law should be clear because it is not effective as an ambiguous protest. So, the protest against Japan should be strong protests on the clear base.
The protest order of Interior Minister Yi, Ji-Yong and Foreign Affairs Minister Pak, Je-Sun for informing Dokdo under the jurisdiction of Japan by "Shimane Prefectual Notice No. 40" on March 28, 1906, the protest of Daehan-mail-sinbo of May 1, 1905, the protest of Hwangsung-sinmun of May 9, 1906 are not effective as international protests.
The protest through the homepage of Northeast Asian History Foundation for "10 issues of Takeshima" by The Ministry of Foreign Affairs of Japan in February, 2008 is not effective as the protest by international law. It should be needed the earliest protest through the diplomatic document by the ministry of Foreign Affairs and Trade.
