At least 3,000 North Korean soldiers now inside Russia, US says

At least 3,000 North Korean soldiers arrived in eastern Russia this month, the White House said Wednesday, and while it remains unclear what exactly they will do, it is a “highly concerning probability” that they will join the fight against Ukraine.

“We assess that between early- to mid-October, North Korea moved at least 3,000 soldiers into eastern Russia,” National Security Council spokesman John Kirby said. “We assess that these soldiers traveled by ship from the Wonsan area in North Korea to Vladivostok, Russia. … We do not yet know whether these soldiers will enter into combat alongside the Russian military, but this is certainly a highly concerning probability. After completing training, these soldiers could travel to western Russia and then engage in combat against the Ukrainian military.”

Earlier Wednesday, Secretary of Defense Lloyd Austin was the first senior US official to confirm on the record that North Korea had deployed troops to Russia as North Korea and Russia have forged increasingly friendly ties since Moscow’s invasion of Ukraine.

“We are seeing evidence that that there are North Korean troops that have gone to Russia,” Austin told reporters traveling with him in Rome on Wednesday. “What, exactly, they’re doing is left to be seen.”

The US does not believe the North Korean troops have reached Ukraine, but the movements have generated deep concern as a potentially serious escalation in the conflict. Austin said the US is still trying to determine what role the North Koreans will play and whether they intend to travel to Ukraine.

“If they’re a co-belligerent, their intention is to participate in this war on Russia’s behalf, that is a very, very serious issue, and it will have impacts not only on in Europe — It will also impact things in the Indo Pacific as well,” Austin said.

Kirby said Wednesday that the US has briefed the Ukrainian government and are keeping in close consultation with allies and partners.

A senior administration official said earlier Wednesday that the training of North Korean soldiers and possible preparation to send them to find to Ukraine is a sign of serious desperation on Russia’s part.

In Rome, Austin said Putin “may be even in more trouble than most people realize.” Kirby added that turning to North Korea for manpower “would be a sign of weakness, not strength, on the part of the Kremlin.” Kirby also said the move is a violation of UN Security Council Resolutions.

Asked what North Korea will get in return for helping Russia with manpower, Austin said the US is still trying to determine that as well.

In recent months, Moscow and Pyongyang have deepened their anti-United States military partnership and the growing alliance has concerned officials in Kyiv and Washington.

“I can tell you one thing, though,” Kirby said Wednesday. “If they do deploy to fight against Ukraine, they’re fair game. They’re fair targets.”

Ukrainian President Volodymyr Zelensky has repeatedly warned that North Korean troops are joining the war on Russia’s behalf, telling a NATO summit last week that “10,000” soldiers and technical personnel were being prepared.

A source in Ukrainian intelligence previously told CNN that a small number of North Koreans have been working with the Russian military, mostly to help with engineering and to exchange information on the use of North Korean ammunition.

Meanwhile, South Korea’s spy agency, the National Intelligence Service, said Friday that North Korea has shipped 1,500 soldiers, including special forces fighters, to Russia for training.
