South Korea said Thursday that it would consider sending arms to Ukraine, a major policy change suggested after Russia and North Korea rattled the region and beyond by signing a pact to come to each other’s defense in the event of war. The comments from a senior presidential official came hours after North Korea’s state media released the details of the agreement, which observers said could mark the strongest connection between Moscow and Pyongyang since the end of the Cold War. It comes at a time when Russia faces growing isolation over its war in Ukraine and both countries face escalating standoffs with the West. According to the text of the deal published by the North’s official Korean Central News Agency, if either country gets invaded and is pushed into a state of war, the other must deploy “all means at its disposal without delay” to provide “military and other assistance.” But the agreement also says that such actions must be in accordance with the laws of both countries and Article 51 of the United Nations Charter, which recognizes a U.N. member state’s right to self-defense. North Korean leader Kim Jong Un and Russian President Vladimir Putin signed the pact at a summit Wednesday in Pyongyang. Both described it as a major upgrade of bilateral relations, covering security, trade, investment, cultural and humanitarian ties. The office of South Korean President Yoon Suk Yeol issued a statement condemning the agreement, calling it a threat to the South’s security and a violation of U.N. Security Council resolutions, and warned that it would have negative consequences on Seoul’s relations with Moscow. “It’s absurd that two parties with a history of launching wars of invasion — the Korean War and the war in Ukraine — are now vowing mutual military cooperation on the premise of a preemptive attack by the international community that will never happen,” Yoon’s office said. At the United Nations in New York, South Korean Foreign Minister Cho Tae-yul called it “deplorable” that Russia would act in violation of multiple U.N. sanctions resolutions against North Korea that Moscow voted for. Yoon’s national security adviser, Chang Ho-jin, said Seoul would reconsider the issue of providing arms to Ukraine to help the country fight off Russia’s invasion. South Korea, a growing arms exporter with a well-equipped military backed by the United States, has provided humanitarian aid and other support to Ukraine while joining U.S.-led economic sanctions against Moscow. But it has not directly provided arms to Kyiv, citing a longstanding policy of not supplying weapons to countries actively engaged in conflict. Speaking to reporters in Hanoi, where he traveled right after Pyongyang, Putin said Thursday that supplying weapons to Ukraine would be “a very big mistake” on South Korea’s part. “I hope it doesn’t happen. If it happens, then we will be making relevant decisions that are unlikely to please the current leadership of South Korea,” he said. South Korea “shouldn’t worry” about Moscow’s agreement with Pyongyang, he said, adding that it bears “no novelty” and merely replaces an old pact from the 1960s that expired. The new agreement calls for military assistance “only if aggression is committed against” one of the parties, and South Korea “is not planning aggression against the Democratic People’s Republic of Korea, which means that they shouldn’t fear […]
