South Korea has expressed its regret over Japan’s decision to maintain its territorial claim over Korea’s easternmost islets of Dokdo in a new set of teaching guidelines for high school teachers.

Foreign Ministry spokesman Moon Tae-young said Friday that the new teaching guidelines have raised concerns that Japan will force erroneous ideas upon future Japanese generations. He said Japan’s decision could end up negatively impacting the development of future-oriented relations with Korea.

Moon stressed that regardless of what the Japanese government claims, the South Korean position is that no territorial dispute exists between the two countries over the islets.

Diplomatic sources in Seoul say the South Korean government will not summon its ambassador to Japan in protest, as has been done in the past.

The sources also said Japan’s decision not to use the name “Dokdo” in the teaching guidelines is considered as Tokyo’s attempt to warm South Korea-Japan relations since the inauguration of the Democratic Party government in Japan.
