Two days after meeting Putin at a spaceport, amid speculation they would agree an arms deal, Kim’s bullet-proof train arrived in Komsomolsk-on-Amur, Russian news agencies reported.
Kim is in the city, an important Russian industrial center, to visit an aviation firm producing military and civil equipment.
The RIA Novosti news agency published footage of Kim’s train arriving in the city, with the red carpet rolled out to greet him.
He was met with flowers, music, a dance group and ceremonial loaves of bread, the Interfax agency said.
Kim, who seldom leaves his country, held talks with Putin at the Vostochny cosmodrome on Wednesday.
Putin said on television Wednesday that Kim “will visit factories where civilian and combat aviation equipment is produced” in Komsomolsk-on-Amur.
His visit to Russia’s far east comes as US officials and experts have said Moscow is interested in buying North Korean ammunition to use in the conflict in Ukraine — an arms deal that would defy global sanctions.
Kim’s visit will last a few more days, Kremlin spokesman Dmitry Peskov announced on Thursday, without giving further details.
