The Russian presidency announced Monday that North Korean leader Kim Jong Un will visit Russia "in the coming days" at the invitation of Russian President Vladimir Putin.

Official media in Pyongyang reported that Kim would hold a summit meeting with Putin during the visit.

The Kremlin said in a statement that the leader of the Democratic People's Republic of Korea, Kim Jong Un, will conduct, "at the invitation of Russian President Vladimir Putin," an "official visit to the Russian Federation in the coming days."

South Korea's Yonhap News Agency had previously reported that Kim's train had apparently left North Korea heading to Russia, citing an unnamed official.

Russia, a historical ally of Pyongyang, has been a major supporter of the isolated state for decades, and relations between them go back to the founding of North Korea 75 years ago.

Putin in July praised Pyongyang's "steadfast support for special military operations against Ukraine."

North Korea and its leader Kim are among the staunchest supporters of Moscow's invasion of Ukraine.

Western countries, led by the United States, fear that Pyongyang may resort to supplying Russia with missiles and missiles.

The White House warned North Korea this month against any such step. US National Security Advisor Jake Sullivan told reporters, "They will pay a price for this in the international community."
