Putin Will Head to North Korea as Ukraine War Redefines Ties With Kim

President Vladimir V. Putin of Russia will head to North Korea for the first time in 24 years on Tuesday after vowing to bring ties with Pyongyang to new heights and jointly combat what he called the “global neocolonial dictatorship” of the United States.

The war against Ukraine has driven the Mr. Putin closer to the North’s leader, Kim Jong-un, 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.
