Seoul - South Korea said Monday that it would recall its ambassador to Japan in protest of Japan's renewed claims on a group of South Korean-administered islets in the Sea of Japan, also known as the East Sea.

Foreign Minister Yu Myung Hwan also planned to summon Japan's ambassador to protest new guidelines for Japanese schools that describe the islets, known as Dokdo in Korean and Takeshima in Japanese, as part of Japanese territory, a spokesman for the Foreign Ministry in Seoul said.

Japan's education ministry on Monday released the supplementary instructions for teachers of junior high schools, which emphasize the importance of explaining Japan's territory to students and the need to recognize the nation's efforts to protect it.

Currently, one of six geography textbooks and three of eight social studies texts for junior high schools mention the islets.

Japan and South Korea have long disputed the ownership of the islands 700 kilometres west of Tokyo and 450 kilometres south-east of Seoul. They have a total area of 187,450 square metres. (dpa)
