Factbox-Kim Jong Un's trips abroad as leader of North Korea
SEOUL (Reuters) -North Korean leader Kim Jong Un is expected to visit Russia's far-eastern port city of Vladivostok by armoured train this month to meet President Vladimir Putin, possibly to discuss supplying Russia with weapons for its war with Ukraine. It is likely to take almost a full day to travel more than 1,000 km (600 miles) to Vladivostok across the border with Russia, taking account of the North's sometimes archaic rail network. While he has made more trips abroad than his father, Kim Jong Il, as leader, Kim's travel is often shrouded in secrecy and heavy security.
