South Korea responded to the Russian-North Korean comprehensive strategic partnership agreement on June 20 and stated that it would reconsider its previous ban on sending lethal military assistance to Ukraine. South Korea's Yonhap News Agency reported that South Korean National Security Director Chang Ho-jin stated that South Korea will reconsider its stance on sending aid to Ukraine following the Russian-North Korean agreement and that South Korea is “grave[ly] concerned” and condemns the agreement.[13] South Korea has notably had a long-standing policy that prevents it from directly transferring arms into active conflict zones—a policy that has forced South Korea to send artillery shells to Ukraine via indirect transfers using third party intermediary states.[14] Chang also noted that any Russian military-technical cooperation with North Korea violates a series of United Nations Security Council (UNSC) resolutions and will result in unspecified corresponding retaliatory measures from South Korea. Chang stated that South Korea will also sanction four ships, five organizations, and eight individuals involved in the transfer of weapons and oil between Russia and North Korea in response to the agreement. North Korean state outlet Korean Central News Agency published the full text of the agreement on June 20, which includes provisions for “immediate military and other assistance... in the event of an armed attack by any state of several states” and “joint activities to strengthen [each country's] defense capabilities... to prevent war.”[15] Several Russian and South Korean sources noted that the agreement is almost identical to the Treaty of Friendship, Cooperation, and Mutual Assistance that the Soviet Union and North Korea signed in 1961.[16]
Russian President Vladimir Putin simultaneously attempted to downplay aspects of the Russia-North Korea agreement potentially in response to South Korea's concerns during a June 20 press conference in Vietnam. Putin reiterated several times during the press conference that the Russian-North Korean agreement mirrors the language of a previous security agreement that both countries signed in 1961 and that the agreement is only a “reproduction” of the terms of the 1961 agreement.[17] Putin stated that South Korea has “nothing to worry about” regarding the new agreement as long as South Korea does not perpetrate acts of aggression against North Korea. Putin threatened, however, that it would be a “very big mistake” for South Korea to supply lethal weapons to Ukraine and that Russia would take unspecified actions in response to such a policy. Putin claimed that the new agreement's clause on providing mutual security assistance does not apply to the war in Ukraine because Ukraine committed acts of aggression towards the Donetsk and Luhansk People's Republics (DNR/LNR) before Russia illegally annexed the territories and that Russia hopes that this agreement will be a “restraining factor” that prevents the situation on the Korean peninsula from intensifying. Putin also claimed that Russia has not asked anyone to “use [their] capabilities” in Ukraine and no one has offered to help Russia in this way, insinuating that there is no threat of third parties getting militarily involved in Ukraine. Putin may have tempered his rhetoric about Russia's June 19 agreement with North Korea in order to quell South Korean concern about the agreement and lull South Korea into reassurance and away from reconsidering its policy on aiding Ukraine. ISW has previously observed that Russia at times seems to be trying to mend its relationship with South Korea to mitigate the impacts of a growing relationship with North Korea, and Putin may have followed up his visit to North Korea with such statements in an effort to appease Seoul.[18]
Putin also used the press conference to reiterate a series of known information operations feigning Russia's interest in good faith negotiations with Ukraine, including by characterizing Russia's offensive operation into Kharkiv Oblast as solely defensive. Putin claimed that he expected the West to reject his June 14 demands for Ukraine's capitulation as a prerequisite for his envisioned peace negotiations and suggested that Russia has previously unsuccessfully presented these demands during “behind-the-scenes negotiations.”[19] Putin claimed that “sensible politicians” will realize that Putin's demands for Ukraine to “completely withdraw” its forces from the administrative borders of Donetsk, Luhansk, Zaporizhia, and Kherson oblasts and officially abandon its intention to join NATO are “realistic” and acceptable conditions for peace. Putin's terms for Ukraine's capitulation violate the basic principles of the United Nations Charter and other cornerstones of international law. Putin stated that any peace negotiations predicated on Russia withdrawing its forces from occupied Ukraine will “never happen.” Russian officials made similar claims about how Kherson City would “forever” remain in Russian occupation before Russian forces abandoned Kherson City in November 2022.[20] Putin reiterated his claims that Russia remains open to peace negotiations to end the war in Ukraine, placing the onus on Ukraine and the West for the lack of progress toward peace negotiations despite the fact that Russian officials, including Putin, continue to publicly signal that they are unwilling to participate in good faith peace negotiations with Ukraine.[21] Putin also reiterated claims that Russian forces are conducting offensive operations in the Kharkiv direction to defend Belgorod Oblast from Ukrainian shelling and that Russian forces have “no goals of approaching Kharkiv [City].”

The Russian Ministry of Foreign Affairs (MFA) criticized South Korean and Japanese objections to the Russian-North Korean strategic partnership agreement and directly tied the agreement to Russian President Vladimir Putin's “Eurasian security architecture” initiative. South Korea's Yonhap News Agency reported on June 21 that South Korean government sources stated that South Korea may send 155mm artillery shells and unspecified air defense systems to Ukraine, after South Korean National Security Director Chang Ho-jin stated on June 20 that South Korea would respond to the Russian-North Korean agreement by reconsidering its policy preventing it from sending aid to Ukraine.[11] The South Korean MFA summoned Russian Ambassador to South Korea Georgiy Zinovyev on June 21 to urge Russia to stop its military cooperation with North Korea.[12] Zinovyev accused South Korea of trying to “threaten and blackmail” Russia and that Russia's cooperation with North Korea is not directed against any other country and claimed that Russian-North Korean cooperation helps strengthen stability on the Korean peninsula.[13] Director of the Russian MFA's Third Department for Asia Lyudmila Vorobyova met on June 21 with Director of the Japanese MFA's Europe Department Masashi Nakagome following the introduction of a new round of Japanese sanctions targeting Russia.[14] The Russian MFA claimed that the Japanese sanctions are the “next step towards the complete destruction” of Russian-Japanese relations, which the Russian MFA claimed are at an all-time low.[15] The Russian MFA claimed that Russia would respond to the sanctions with “tough and painful countermeasures.” The Russian MFA responded to Nakagome’s protests about the Russian-North Korean strategic partnership by outlining Putin's June 14 initiative for the creation of “a new continent-wide security architecture” in Eurasia.
