South Korean President Lee Jae Myung is keeping Ukraine inside Seoul’s diplomatic orbit without moving into the most sensitive territory for his government. In his first summit with Ukrainian President Volodymyr Zelenskyy since taking office, Lee pledged $100 million in support for Kyiv while reaffirming that South Korea will not provide lethal weapons.
The meeting, held in Ankara on the sidelines of the NATO summit, offered an early look at how Lee plans to handle one of the hardest questions facing South Korea’s foreign policy. Seoul is a U.S. treaty ally, a major arms producer and an increasingly important partner for NATO, but it also sits next to North Korea and has to weigh the consequences of Russia’s deepening military ties with Pyongyang.
Lee told Zelenskyy that South Korea would continue humanitarian assistance for the Ukrainian people and take part in international efforts to support Ukraine’s recovery and reconstruction. Zelenskyy thanked South Korea for its support and said he hoped to work more closely with Seoul and other partners to bring the war to an end and rebuild Ukraine.
The pledge signals continuity rather than a sharp turn under Lee’s new government. South Korea has supported Ukraine through financial, humanitarian and nonlethal channels, but it has avoided sending lethal weapons directly to Kyiv. That line remains in place even as Seoul expands its public commitment to Ukraine at a NATO gathering.
The war has also become more directly tied to South Korea’s own security concerns. Lee and Zelenskyy discussed North Korean prisoners of war captured in Ukraine and agreed that the issue should be handled under international law and humanitarian principles while respecting the individuals’ wishes. The discussion underscored how North Korea’s role in Russia’s war effort has turned the conflict into a matter that reaches well beyond Europe.
Lee had made a similar point a day earlier in a meeting with NATO Secretary General Mark Rutte and leaders of NATO’s Indo Pacific partners. He said instability from the war in Ukraine should not spread to Northeast Asia and called for an early end to the conflict and the establishment of peace.
South Korean officials said the new $100 million pledge expands Seoul’s existing support rather than changing its military policy. Wi Sung lac, South Korea’s national security adviser, said the commitment builds on aid that Seoul has provided through humanitarian and other channels. A senior presidential official said South Korea’s position against providing lethal weapons remains unchanged and that the government is preparing support in other areas.
Lee’s approach places South Korea in a familiar but delicate position. Seoul is staying aligned with the coalition backing Ukraine, but it is defining its role through aid, reconstruction and diplomacy rather than direct arms supplies. That balance reflects the limits of how far South Korea is prepared to go as the Ukraine war becomes increasingly connected to the security equation on the Korean Peninsula.
