During the politburo meeting of the central committee of the Workers' Party on Wednesday, officials analysed the significance of Kim's visit to Russia and introduced long-term plans for developing their bilateral relations, the Korean Central News Agency (KCNA) said.

Russian Ambassador Andrey Kulik was summoned Seoul's foreign ministry on Tuesday over Moscow's alleged discussions of military cooperation with Pyongyang during the summit between North Korean leader Kim Jong-un and Russian President Vladimir Putin, Yonhap news agency reported.

The train carrying Kim departed the railway station in Russia's Far Eastern city of Artyom as Russian officials saw him off, RIA Novosti news agency said. Kim also waved and gave a salute to the Russian officials, Yonhap news agency reported.

Kim arrived at a railway station in the city earlier in the day and was welcomed in accordance with traditions for a special guest, Yonhap News Agency quoted local Russian media outlets as saying.

Kim extended the invitation at an official dinner with Putin on Wednesday night after their summit, the North's official Korean Central News Agency (KCNA) said.

Analysts have predicted that North Korea may agree to supply Russia with ammunition and weaponry for its war in Ukraine, reports Yonhap News Agency.

Russia's state-run TASS News Agency said that while Putin flew to Vostochny from the Primorye Region where he participated in the Eastern Economic Forum, Kim arrived on a train to the spaceport's rail station.

Kim's remarks came as the leaders are expected to meet for their first summit in four years in Russia to discuss a possible arms deal as they seek to strengthen military cooperation, Yonhap news agency reported.

According to the BBC report, the green train with a yellow stripe train named 'Taeyangho', the Korean word for the sun and a symbolic reference to North Korea's founder Kim Il Sung, runs along at a speed of about 50km/h because of its heavy armoured protection.

The North's official Korean Central News Agency (KCNA) confirmed early Tuesday that Kim had left Pyongyang for Russia aboard his bulletproof train on Sunday afternoon, accompanied by leading officials of the regime's ruling party and the armed forces, reports Yonhap News Agency.
