Russia–South Korea relations

Russia–South Korea relations (Russian: Российско-южнокорейские отношения, Rossiisko-yuzhnokoreyskie otnosheniya, Korean: 한러 관계, hanreo gwangye) or Russian–South Korean relations are the bilateral foreign relations between Russia and South Korea. Modern relations between the two countries began on September 30, 1990. Due to the 2022 Russian invasion of Ukraine, relations became very tense after South Korea imposed sanctions against Russia. Russia placed South Korea on a list of "unfriendly countries", along with Taiwan, Japan, Singapore, the United States, European Union members, NATO members (except Turkey), Australia, New Zealand, Switzerland, Micronesia and Ukraine.

Immediately following Japan's 1910-1945 colonial rule of Korea, the Cold War between the Soviet Union and the United States created the division of Korea into North and South states. Thereafter, since the two sides were separated by North Korea and opposing ideologies, there was little contact until the dissolution of the Soviet Union.

Since the 1990s, there has been greater trade and cooperation between the two nations. The total trade volume between South Korea and Russia in 2003 was 4.2 billion US dollars, which increased to 24.8 billion US dollars in 2018.
