North Korean leader Kim Jong Un visited a fighter jet factory in the Russian Far East city of Komsomolsk-on-Amur on Friday after arriving there by train in the morning, Tass news agency reported.

The plant in the Khabarovsk region manufactures warplanes such as Su-35 and Su-57 fighter jets as well as the Sukhoi Superjet 100 civilian aircraft, the news agency said.

Kim was accompanied by Russian Deputy Prime Minister Denis Manturov, who also serves as industry and trade minister, according to sources close to Russian authorities.

Kim has been visiting Russia at the invitation of President Vladimir Putin and Pyongyang is believed to be aiming to ramp up its military cooperation with Moscow through the plant visit.

On Wednesday, Kim met with Putin for the first time in over four years at the Vostochny Cosmodrome space launch center amid concern that North Korea could provide ammunition to Russia, which is struggling to replenish its rapidly depleting stockpiles as its war in Ukraine drags on.

After visiting Komsomolsk-on-Amur, the North Korean leader is expected to travel to Vladivostok to inspect the Russian military's Pacific fleet, the sources said.
