Japan defense force chopper nears disputed islets, draws Korean warning
A helicopter from Japan's Maritime Self-Defense Force flew close to South Korean-controlled islets claimed by Japan on Sept. 21 and returned after a warning was issued by the South Korean military, broadcaster KBS said Thursday.
The MSDF said it was aware the chopper entered the air defense zone as claimed by South Korea while conducting a take-off and landing drill on MSDF Destroyer Ariake, positioned around 50 kilometers east of Takeshima Islands, known as Dokdo in Korean.
A Japanese Defense Ministry official said, "There was no problem since it was on high seas."
