Promotional footage of a huge national flag of South Korea on its easternmost island of Dokdo was unveiled Sunday to mark Dokdo Day, a social media post showed.
A 30-by-20-meter Taegeukgi, unfurled by 70 South Koreans at a pier on Dokdo Island, was captured in 60-second footage taken by drone, according to Seo Kyoung-duk, a professor at Sungshin Women's University in Seoul, on social media.
The video also contained various images of Dokdo Island in the East Sea and a message recommending foreigners visit as part of a global promotional campaign for Dokdo.
South Korea has said Dokdo is historically, geographically and under international law its territory, categorically rejecting Japan's claim to the territory.
South Korea keeps a small police detachment on the islets, to showcase its effective control of Dokdo. (Yonhap)
