"한일 국교 정상화" refers to the normalization of diplomatic relations between South Korea and Japan. This process began in the early 1960s, culminating in the signing of the Korea-Japan Treaty in 1965, which established formal ties and aimed to resolve issues stemming from Japan's colonial rule over Korea. The normalization led to various agreements, including economic cooperation and cultural exchanges. However, historical disputes, such as those related to wartime labor and comfort women, continue to affect relations. Despite these challenges, both nations strive to maintain a cooperative partnership in regional security and economic development.
