South Korea is keeping lethal aid to Ukraine off the table while continuing humanitarian and reconstruction support, Yonhap reported on 10 August. The outlet cited a senior South Korean Foreign Ministry official.

South Korea’s response maintains its established policy of providing humanitarian and nonlethal support to Ukraine, but not direct weapons. Seoul previously helped move artillery shells to Ukraine through the United States. While South Korea arms NATO members with K2 tanks and K9 howitzers to free up older kit for the Ukrainian front, it still draws the line at any direct transfer to Kyiv. Seoul rejects Ukraine’s purchase requests as North Korea sends Russia ammunition and troops in exchange for money and military technology.

South Korean law bars direct exports of lethal weapons to countries in active conflict, a rule rooted in constitutional principles and Seoul's wariness of antagonizing Moscow and Beijing while managing the threat from the North.

Ukraine is seeking South Korean interceptor missiles for its air defenses. The official neither addressed the request specifically nor formally rejected it:

“South Korea’s supply of defense materials to any country has always been carried out in accordance with domestic law,” the official said. Seoul will continue to support Ukraine’s recovery through assistance in energy, infrastructure, healthcare, and education. 

The official also declined to confirm whether Seoul and Kyiv were discussing military support. However, he said Moscow-Pyongyang military cooperation “is directly related to our security and violates the United Nations resolutions” and should stop immediately.

Seoul’s indirect aid stopped short of direct arms transfers

In 2023, Seoul transferred hundreds of thousands of 155 mm shells to the United States under a confidential arrangement. Washington then arranged for them to reach Ukraine, The Wall Street Journal reported.

South Korean exports have also helped NATO members replace weapons sent to Kyiv. Poland bought South Korean K2 tanks and K9 howitzers while transferring older tanks and Polish-built Krab artillery systems to Ukraine.

Yet Seoul rejected Ukraine’s request to buy air-defense systems, radars, and artillery propellant in November 2024. In February 2026, it still limited support to humanitarian and nonlethal aid while considering NATO’s request to help purchase US weapons for Ukraine.

North Korean deployments bring the war closer to Seoul

Ukrainian President Volodymyr Zelenskyy said a decision had been made to deploy 30,000–50,000 more North Koreans to Russia. He warned that they would gain modern combat experience and Russian technology that could later threaten Asian countries. Kyiv wants South Korean air defenses and has offered cooperation on drones.

The South Korean official cited by Yonhap declined to confirm either the reported deployment or Zelenskyy’s statement that Ukrainian and South Korean diplomats were discussing possible cooperation.

North Korea is already believed to have sent approximately 20,000 combat troops and military engineers to Russia’s Kursk region, according to Yonhap. Pyongyang has earned as much as $22 billion from arming Russia, helping it finance conventional and nuclear forces.

The Japanese outlet Kyodo News reported in November 2025 that North Korea had transferred about 6.5 million rocket and artillery munitions in exchange for Russian air-defense, space, and nuclear technologies.  Moscow and Pyongyang’s 2024 mutual defense pact formalized the expanding military relationship.
