South Korea will reject a reported proposal by Japan to take the issue of Dokdo, Seoul's easternmost islets claimed by Tokyo as its territory, to the International Court of Justice (ICJ), reaffirming its stance that Dokdo is "clearly a Korean territory historically, geographically and under international law," officials said Friday.

Japan has considered asking the ICJ to resolve the issue of Dokdo since President Lee Myung-bak made an unprecedented visit to the islets on Aug. 10 and Tokyo is set to announce the move as soon as Friday, Japan's Kyodo news agency reported.

Prospects for taking the issue of Dokdo, which lies closer to South Korea in the body of water between the Korean Peninsula and Japan, to the ICJ are elusive because Tokyo must secure Seoul's consent to have the case heard at the court.

"The government's stance is that there is no territorial dispute over Dokdo because it is clearly a Korean territory historically, geographically and under international law," a senior official at Seoul's foreign ministry said.

"So, we have neither any reason to go the ICJ nor any intention to go there," the official said on the condition of anonymity.

It would be the first time since 1962 for Japan to make such a proposal to South Korea.

Another ministry official said it would be a "provocation against our sovereignty" if Japan formally decides to take the issue of Dokdo to the court.

As soon as Japan announces the move, the Korean government will take necessary diplomatic actions, the official said.

Dokdo has long been a thorn in relations between South Korea and Japan. South Korea keeps a small police detachment on the islets, effectively controlling them.

Japan has long laid claims to Dokdo in school textbooks, government reports and other ways, undercutting better ties between the neighboring nations.

South Koreans see those claims as amounting to denying Korea's rights because the country regained independence from 1910-45 Japanese colonial rule and reclaimed sovereignty over its territory, which includes Dokdo and many other islands around the Korean Peninsula.

The territorial claims have been also viewed by South Koreans as a sign Japan has not fully repented for its imperialist past, along with Tokyo's strict unwillingness to address long-running grievances of elderly Korean women forced into sexual slavery for Japanese troops during World War II.
