Russia has warned South Korea against sending weapons to Ukraine after Seoul said it may provide military aid to Kyiv if there is a large-scale attack on civilians. So far, South Korea has only given non-lethal and humanitarian assistance to Ukraine. The Kremlin says that the start of arms supplies would mean indirect involvement in the Ukraine conflict. Russia’s ex-leader Dmitry Medvedev warned that Moscow could send weapons to North Korea if Seoul sends weapons to Ukraine.
