South Korean President Yoon Suk-yeol stated on Monday during an interview with Reuters that South Korea’s support for Ukraine would be determined based on the level of military cooperation between Russia and North Korea, which he described as a “distinct threat and grave challenge to the peace and security on the Korean Peninsula and in Europe.”

Yoon also expressed concern over Russia’s violation of U.N. sanctions resolutions through its involvement with North Korea, warning of negative consequences for ROK-Russia relations. Yoon highlighted plans to strengthen cooperation with NATO allies through a joint cyber defense training exercise and a meeting on the responsible military use of artificial intelligence, both set to take place in Seoul in September.
