South Korea slammed Japan Tuesday for uploading a video on YouTube that lays claim to Seoul's easternmost islets of Dokdo in the East Sea, calling it "a grave provocation."
In late December, the Japanese government uploaded the 17-minute video that introduces a picture book showing that Japanese went fishing in waters off the Dokdo islets in the past. The footage was made for the purpose of being used in schools.
Japan has laid claim to the Dokdo islets that lie closer to Seoul than Japan in the waters between the two countries, but Seoul has rejected Japan's claim as nonsense as it regained its independence from Japan's 1910-45 colonial rule and reclaimed sovereignty over its territory, including Dokdo
