Russia has warned South Korea against sending arms to Ukraine, threatening to deliver weapons to its North Korean enemy as retaliation.

The warning came after South Korean President Yoon Suk-yeol told Reuters in an exclusive interview that it might provide more than just humanitarian and economic aid to Ukraine if it faces a significant civilian attack.

Since the onset of the conflict, Seoul has been supporting Kyiv with everything but military assistance. Despite condemning Russia’s aggressive “special military operation,” South Korea has maintained a low-key stance and avoided antagonizing Moscow for economic and security reasons.

Not only the companies based in Russia will be in jeopardy, but also tensions with North Korea will likely increase considering Moscow’s influence over Pyongyang. So, South Korea has dug in its heels and not changed their minds despite the West’s pressure for weapons supply.

Shortly after the interview was released, Kremlin Spokesman Dmitry Peskov told reporters that Seoul’s sending weapons to Kyiv “would imply a certain involvement” in the conflict. Peskov noted that this will also mean South Korea has cemented its “unfriendly position in this story.”
