Russia's state-run news agency says North Korean leader Kim Jong Un has wrapped up a visit to the Russian far eastern city of Komsomolsk-on-Amur, where he inspected a fighter jet manufacturing plant.
TASS news agency earlier reported that Kim arrived on a special train in the city in the Khabarovsk region on Friday morning, and that a welcome ceremony was held at the railway station. A limousine thought to be carrying Kim was later seen near the station.
The Russian government said on its official website that Kim inspected facilities that manufacture Sukhoi fighter jets and other aircraft. He was accompanied by Russian Deputy Prime Minister Denis Manturov, who also serves as minister of industry and trade.
The North Korean leader is said to have viewed a demonstration flight of a Su-35 fighter jet. Kim's father, the late Kim Jong Il, had also inspected the production site in 2002.
Manturov said Russia and North Korea are considering cooperating in aircraft manufacturing and other fields. He stressed that this is particularly important in achieving both countries' technical goals.
Kim held a summit with Russian President Vladimir Putin on Wednesday at the Vostochny spaceport. They are said to have held in-depth talks on cooperation in military technology.
TASS says the North Korean leader left Komsomolsk-on-Amur on Friday afternoon. He is due to head to Vladivostok, a central city in the Russian Far East, to view the Russian Navy's Pacific Fleet.
Russian media say the defense minister, Sergei Shoigu, may accompany Kim.
