The diplomatic documents Seoul released Friday detail behind-the-scenes negotiations between Japan and South Korea over reparations for Korean victims during Japan's colonial rule and other issues prior to the normalization of bilateral ties in 1965.
Seoul, which made public some of the archive documents in January, said it has now disclosed all material relating to the 1965 Treaty on Basic Relations Between Japan and the Republic of Korea.
The 35,350 pages detail negotiations over property claims, including how the Japanese and South Korean sides tried to narrow the gap between their positions.
