How much further cooperation between Russia and North Korea will go depends on how the world will react, though it is not reacting enough so far, Ukrainian President Volodymyr Zelenskyy believes.

"What will happen next, how deep it goes, I think it really depends on how the world reacts. The world is not reacting enough so that Putin does not make a decision and invite even more North Korean army to the territory of the war against Ukraine," Zelenskyy said in an interview with Suspilne on the occasion of the 100th anniversary of Ukrainian Radio.

The President recalled that there are more than 11,000 North Korean soldiers in Kursk region, in addition, the DPRK has transferred at least 3.5 million 155-caliber artillery and missiles to Russia.

The head of the Ukrainian state also believes that Iran is an active participant in the war against Ukraine, since it provided Russia and built factories on its territory for the production of shaheds.

In addition, according to the president, he is sure that the Iranians on the territory of the Russian Federation taught Russians how to operate drones.

"The first attacks by Iranian drones against Ukraine, the Ukrainian population, have had devastating results. Were there Iranians there [in the Russian Federation]? I am sure, yes, according to intelligence," Zelenskyy stressed.
