North Korean leader Kim Jong Un met Russian President Vladimir Putin on Wednesday at the Vostochny Cosmodrome in Russia's far east, with the the two holding "negotiations" — including one-on-one talks — as Putin hinted at offering Pyongyang help in its quest to build spy satellites.

After shaking hands upon Kim's arrival by train, Putin escorted the North Korean leader on a tour of the spaceport near Russia's border with China — a conspicuous choice considering Pyongyang's two failed attempts to put a reconnaissance satellite into low-Earth orbit earlier this year.

Kim's visit included a close-up look at an assembly plant for Moscow's advanced Angara and Soyuz-2 space launch vehicles, Russian news agencies reported.
