Russian President Vladimir Putin has praised North Korea for "firmly supporting" Moscow's war in Ukraine, ahead of his first visit to Pyongyang in 24 years.

Russian President Vladimir Putin is expected to visit Pyongyang to meet North Korean leader Kim Jong Un on Tuesday, marking his first visit to the North Korean capital since 2000. The meeting follows their last encounter in September at Russia's Vostochny cosmodrome. In a letter published in North Korean state media, Putin pledged to strengthen trade and security ties with Pyongyang independently from Western influence.

Putin expressed support for North Korea's efforts to safeguard its interests amidst what he described as US pressure, blackmail, and military threats. He emphasized joint opposition to Western ambitions that seek to hinder a multipolar world order based on justice and mutual respect.

The United States has expressed concerns about the deepening relationship between Russia and North Korea. The Kremlin described Putin's visit as a "friendly state visit," with plans for potential agreements on security issues and joint public statements. A parade in Kim Il Sung square and cultural engagements are anticipated during Putin's visit, including a visit to North Korea's only Orthodox Church.

Putin will be accompanied by his new defense minister, Andrei Belousov, along with Foreign Minister Sergei Lavrov and Deputy Prime Minister Alexander Novak. The visit underscores Russia's efforts to strengthen ties with North Korea amid global geopolitical tensions, including its conflict in Ukraine.

The relationship between Russia and North Korea has grown stronger in recent years, particularly following Russia's increased global isolation due to its actions in Ukraine. This visit is seen as a move by Putin to bolster ties with an old Cold War ally while countering perceived efforts to isolate Russia on the world stage.

North Korea needs help with space technology after its recent failure to put a second spy satellite into orbit - as well as food, fuel, and foreign currency.

While Russia faces a continued shortage of weapons in its war in Ukraine.

Washington and Seoul have accused Pyongyang of supplying Moscow with artillery and other equipment, most likely in exchange for food and military aid and technology. Both North Korea and Russia deny the existence of an arms deal.

After North Korea, Mr Putin is expected to visit Vietnam, a Communist state and long-time ally, where both countries are expected to discuss issues such as trade.
