Trump, Putin, Xi: Kim Jong Un's overseas trips in pictures
Yahoo News UK takes a look at Kim's foreign trips since he became leader in 2011.
North Korean leader Kim Jong Un is expected to meet president Vladimir Putin in Russia this month, which would be his first official overseas trip in more than four years.
Kim will travel to the far-eastern port city of Vladivostok by armoured train to meet Putin, possibly to discuss supplying Russia with weapons for its war with Ukraine, according to reports.
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 North Korea's poor 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.
The trip, which has not been officially confirmed, would be his first since the coronavirus pandemic.
