North Korea has already sent soldiers, missiles and ammunition to Russia earlier in the war, in exchange for financial support and military technology, among other things.
"At first we talked about hundreds, then thousands, and now a decision has been made to deploy between 30,000 and 50,000 North Koreans on Russian territory," Zelenskyy wrote in a post on X.
He further claims that one of North Korea's aims is to gain experience in modern warfare. Zelenskyy warns that North Korea could thus pose a greater threat to countries in its vicinity.
"Therefore, I believe that South Korea should have closer cooperation with Ukraine," the president writes.
