The Kremlin says North Korean troops fighting alongside the Russian military in support of its offensive in Ukraine are restricted to deployment on Russian territory.

According to Russia's state-run RIA Novosti news agency on Friday, Kremlin spokesperson Dmitry Peskov said North Korean soldiers have not been deployed on Ukrainian soil.

He made the remarks while attending the Eastern Economic Forum(EEF) underway in Vladivostok. 

Some eleven-thousand North Korean soldiers who were sent to Russia last October supported Russian forces in Russia's Kursk region that had been occupied by the Ukrainian military.

In April, Moscow said it managed to drive out the Ukrainian forces from Kursk thanks to support from the North Korean troops.

During a meeting with North Korean leader Kim Jong-un on Wednesday, following Beijing's Victory Day military parade, Russian President Vladimir Putin said Russia will never forget North Korea's role in its fight against "modern neo-Nazism."
