Russia's president, Vladimir Putin, is to visit North Korea on a state visit and will be there on Tuesday and Wednesday this week, reports Russian state media.
During the meeting, "important documents" will be signed, according to a Kremlin adviser.
It was previously almost confirmed that Putin would travel there, but not when.
"Several documents will be signed", including some that will be "important, very significant documents", reports Kremlin adviser Yuri Ushakov, according to state media. It is also said that the two leaders will speak to the media during the visit, according to Ushakov.
A week ago, preparations were in full swing in Pyongyang, said Russia's ambassador there to the Russian daily Vedomosti.
After the visit to North Korea, Putin will travel on to Vietnam for a two-day visit, reports the state-controlled news agency Ria.
Vladimir Putin has visited North Korea once before, in 2000. Then, he was relatively new to the presidency and North Korea was ruled by the former leader Kim Jong-Il. The current North Korean leader, Kim Jong-Un, was, however, in Russia and met Putin as recently as last autumn.
Russia's government has strengthened its contacts with North Korea alongside the ongoing invasion war in Ukraine. North Korea is said to have supplied Russia with weapons, among other things.
