The Foreign Ministry on Friday again summoned the chief of mission at the Japanese Embassy in Seoul to lodge a protest against an English-language video promoting Tokyo's colonial claim to Korea's Dokdo islets.
The Foreign Ministry first summoned Takashi Kurai on Oct. 23, when the Japanese Foreign Ministry put a Japanese-language version of the video on YouTube.
A Foreign Ministry official said that was a "warning" that Seoul regards the video campaign as a "serious problem."
Foreign Ministry spokesman Cho Tae-yong said the Korean government "strongly protests" against the clips and wants them removed immediately.
He warned of "firm measures" against any attempt by Tokyo to "damage Korea's sovereignty" and "strongly urges Japan to wake up to the truth." He warned that the campaign would only harm Japan.
But the incident is not expected to affect bilateral security talks scheduled for the middle of this month. A Foreign Ministry official said Seoul awaits Tokyo's response but added that the Dokdo controversy "will not halt working-level talks between Korea and Japan." However, he said talks between the foreign ministers of the two countries now seem less likely.
The clips are part of a wider campaign by Japan's rightwing administration to stir voters with the rhetoric of resurgent nationalism and establish some sort of international legitimacy for the flimsy claim.
