You’re joking, sure… but due to the high tensions with South Korea, North Korea has an insane stockpile of conventional weapons and a large capacity to make more. These arms are likely being traded for oil, consumer goods and food - all of which North Korea has historically had shortages of (since so much of their economy is militarily focused).
Additionally, NK got significant military aide from the USSR so their artillery gauges are actually compatible with Russian equipment both for historical stockpiles and domestically produced.
