The Ukrainian defense and aerospace complexes did not supply weapons and military technology to North Korea, and false information disseminated by some foreign media about the alleged transfer of missile technology by Yuzhmash to the DPRK is most likely triggered by Russian special services, NSDC Secretary Oleksandr Turchynov has said.

"This information doesn't have a leg to stand on, is provocative in its content, and most likely provoked by Russian special services to cover their own crimes," the press service of the NSDC quoted Turchynov as saying on Monday.

"Ukraine has never supplied rocket engines and any missile technology to North Korea. And we believe that this anti-Ukrainian campaign was provoked by Russian special services to cover their participation in North Korean nuclear and missile programs," the National Security and Defense Council Secretary said.

Ukraine considers North Korea's regime "totalitarian, dangerous, and unpredictable and supports all sanctions against this country," Turchynov said.

Earlier on Monday, the New York Times published an article on its website saying that analysts studying photographs of North Korean leader Kim Jong Un inspecting new rocket engines had concluded "that they derive from designs that once powered the Soviet Union's missile fleet."

Those engines were manufactured at only a few plants in the former Soviet Union. U.S. government investigators and experts focused their inquiries on the Ukrainian Yuzhmash factory. During the Cold War, the factory in the city of Dnipro built powerful missiles for the Soviet arsenal, including the giant SS-18. It remained one of Russia's primary producers of missiles even after Ukraine's independence.

Following Ukrainian President Viktor Yanukovych's removal from power in 2014, Yuzhmash fell on hard times, suffering a lack of funding. Experts believe it is the most likely source of the engines that powered intercontinental ballistic missiles launched by North Korea in July.
