South Korea condemned Japan on Friday for renewing its claim to islands in new high school education guidelines adopted by the education ministry the same day.

The South Korean Foreign Ministry summoned Japanese Ambassador to South Korea Yasumasa Nagamine the same day and lodged its protest over the Japanese claims to the South Korean-controlled islets, known as Dokdo in South Korea and Takeshima in Japan.

South Korea "strongly condemns the Japanese government's final adoption ... of the courses of study for high schools that contain unjustifiable claims to Dokdo, an integral part of (South Korea's) territory . . . and sternly demands an immediate withdrawal," a ministry spokesperson said in a statement.
