Putin Arrives in North Korea as Ukraine War Redefines Ties With Kim

President Vladimir V. Putin of Russia has arrived in North Korea, according to Russian state media, visiting for the first time in 24 years after vowing to bring ties with Pyongyang to new heights and jointly rebuff what he called the “global neocolonial dictatorship” of the United States.

The North’s leader, Kim Jong-un, met the Russian president on the airport tarmac early Wednesday local time, Russian state news agencies reported.

Mr. Putin arrived in the dead of night, descending from his airplane to a red carpet lined by uniformed guards to embrace the waiting North Korean leader, video later released by the Kremlin showed. Mr. Kim ushered Mr. Putin into a Russian-made Aurus limousine that he had received from him last year.

The war against Ukraine has driven Mr. Putin closer to Mr. Kim, who has won new status with the Kremlin by opening his vast munitions stores to Moscow.

Nine months ago, after Mr. Kim arrived by armored train in the Russian Far East, the two men met at a Russian cosmodrome and toasted their “sacred struggle” against the West. The North Korean leader, in between visiting sensitive Russian rocket and fighter jet facilities, invited Mr. Putin to make a reciprocal visit.

Now, the Russian president has taken him up on the offer. And the deepening relationship between the two authoritarian leaders poses a particular challenge for Washington. The United States once relied on Moscow’s cooperation in its attempts to curb North Korea’s nuclear and missile program. Now, it faces a Kremlin intent on playing spoiler to American geopolitical interests around the world.

Russian state media released footage showing large Russian flags and portraits of a smiling Mr. Putin lining the streets of Pyongyang as North Korea prepared to welcome the Russian leader.

What does Russia want?

Ahead of the trip, Mr. Putin issued an order authorizing the conclusion of a new “comprehensive strategic partnership” agreement with North Korea.

He also published an article in Rodong, the North’s main newspaper, praising Mr. Kim for resisting “economic pressure, provocations, blackmail and military threats from the United States” and thanking Pyongyang for its strong support of Russia’s operations in Ukraine.

Victory over Ukraine has been the guiding principle of Russian foreign policy for more than two years, and Mr. Putin’s top priority on the trip will be to ensure North Korea’s continued cooperation in helping him achieve his aims on the battlefield.

North Korea is one of the world’s most impoverished and isolated countries, but it has one of the biggest militaries.

The exact scope of the North’s military aid for Moscow’s war is unclear. Many analysts say the contribution has been meaningful, because the Russian military requires ever more ammunition in its war of attrition against Kyiv. Russian forces have recently been making territorial gains against Ukraine in part because they are able to expend more ammunition.

In an interview with Bloomberg last week, the South Korean defense minister, Shin Won-sik, said Seoul had tracked at least 10,000 shipping containers that could hold as many as 4.8 million artillery shells being ferried from North Korea to Russia. The minister predicted that Mr. Putin would ask for more during his trip.

Before Mr. Kim’s visit to Russia last year, U.S. intelligence reported that Moscow had purchased millions of artillery shells from North Korea. The United States has since accused Russia at the United Nations of firing multiple North Korean ballistic missiles into Ukraine.

But questions about the quality of the North’s supplies have arisen. Officials in Kyiv have said that Russia fired roughly 50 North Korean ballistic missiles at Ukrainian territory last winter and that the fail rate of the weapons was high.

The burgeoning relationship with Moscow has already yielded dividends for Pyongyang. In March, Russia vetoed the annual renewal of the U.N. panel of experts that had been scrutinizing North Korean sanctions violations for 15 years. The move highlighted the drastic shift in Moscow’s stance toward Pyongyang after years of playing a role in U.N. disarmament efforts there.

Before their mandate expired, U.N. monitors verified that debris from a January attack on the Ukrainian city of Kharkiv had come from a North Korean missile and said the weapons transfer had violated the U.N. arms embargo on Pyongyang, according to Reuters. The embargo prohibits the export and import of weapons.

Mr. Putin is unlikely to acknowledge any ammunition or weapons deliveries during the trip. Russia has denied any military transfers that violate the U.N. embargo.

The Kremlin foreign policy aide, Yuri V. Ushakov, told journalists at a briefing on Monday that the two leaders would discuss energy, transport, agriculture, economic and security issues during the trip.

Mr. Putin will also visit Vietnam later this week, underscoring the Kremlin’s propensity to contest American interests even in nations where Washington has been improving its ties. The Russian leader’s trip there comes after President Biden visited in September.

What does North Korea want?

Mr. Kim, whose grandfather came to power with Moscow’s backing in 1948 and founded North Korea, has been steadily expanding his arsenal of high-end weapons and looking increasingly for the Kremlin’s help.

The warming of relations between Moscow and Pyongyang has led to a breakdown of international efforts aimed at containing North Korea’s nuclear and missile ambitions and has raised questions about future sanctions enforcement.

Since the two leaders met last year, questions have persisted about what Mr. Kim has received in return for supplying Moscow with ballistic missiles and much-needed artillery shells.

Among other things, the conflict has given Pyongyang the rare opportunity to evaluate the performance of its missiles in live combat and potentially perfect their design.

North Korea would also welcome greater access to Russia’s sophisticated military technology, including its extensive knowledge of satellites. Two months after Mr. Kim’s visit to Russia last year, North Korea put its first military reconnaissance satellite into orbit, a launch that South Korean officials said had been aided by technological assistance from Moscow.

Russia, which has the world’s largest arsenal of nuclear weapons and one of its most sophisticated submarine programs, possesses a range of other technologies of interest to North Korea. Despite disarmament efforts over many years by Washington and the United Nations, Pyongyang has conducted six nuclear tests and developed intercontinental ballistic missiles capable of reaching the United States.

Isolated from the rest of the world owing to international sanctions, North Korea has a range of needs outside the military sector that Moscow could also help meet. South Korean officials have said that Russia, the world’s biggest wheat exporter, is supplying food and raw materials, as well as parts for weapons manufacturing.

In the article published in Rodong ahead of the trip, Mr. Putin said that Moscow would support North Korea’s struggle against “the cunning, dangerous and aggressive enemy” by deepening economic relations and establishing a new trade settlement system free from American interference.

Mr. Ushakov said that Russia’s trade with North Korea reached $34.4 million in 2023, nine times the amount of the previous year. He said the summit would include a discussion about restoring humanitarian ties that were suspended during the pandemic because of North Korea’s strict rules.
