South Korea has published an English version of its information booklet on Dokdo, the government said Tuesday, in an effort to strengthen the country’s control of the islets also claimed by Japan.

The book offers basic information about Dokdo, along with geography of the islets in the East Sea, according to the Ministry of Land, Infrastructure and Transport.

The book, “The Geography of Dokdo,” will soon be distributed to libraries and South Korean diplomatic missions around the world, it said.

The islets have traditionally been South Korean territories with the country still effectively controlling them. However, Japan continues to lay claim over Dokdo, citing its brief control over the islets during its 1910-1945 colonial rule of Korea.

“The English version of the Geography of Dokdo...will become an important source of information for foreigners in understanding current conditions, as well as geographical features of our land Dokdo,” the ministry said in a press release. (Yonhap News)
