The government maintained a cautious stance on Ukraine's request for air defense support and other military provisions, a senior government official said Monday, amid Ukrainian claims that North Korea is preparing to send more troops to support Russia in its war against Ukraine.

"South Korea's supply of defense materials to any country has always been carried out in accordance with domestic law," a senior foreign ministry official said.

"The government has offered support to Ukraine in a variety of sectors, including energy, infrastructure, healthcare and education, and will continue reviewing measures to help Ukraine recover peace and rebuild," the official said, appearing to reaffirm Seoul's position that supplying weapons to Ukraine remains off the table.

South Korea has maintained a policy of providing Ukraine humanitarian assistance while withholding lethal weapons.
