Top diplomatic and military officials from the United States and South Korea are set to convene in Washington this Thursday as the two allies closely monitor and express concerns about North Korea’s deployment of about 10,000 troops to Russia.

Meanwhile, U.S. officials and analysts say that China could be displeased by Russia’s growing influence over North Korea, and that if Beijing chose, it could restrict exports of materials that Pyongyang might use for munitions production.

U.S. Secretary of State Antony Blinken and Secretary of Defense Lloyd Austin will co-host South Korean Minister of Foreign Affairs Cho Tae-yul and Minister of Defense Kim Yong-hyun to coordinate on pressing security threats facing the alliance.

State Department spokesperson Matthew Miller told VOA during Monday’s briefing that high on the agenda would be discussion of “North Korea’s expanding relationship with Russia,” which includes the deployment of North Korean troops to Russia; various other provocative actions by North Korea in recent months; and the U.S. commitment to security in the Indo-Pacific region.

The consultation between Washington and Seoul will come two weeks after establishment of the Multilateral Sanctions Monitoring Team, a group formed by the United States, South Korea, Japan and other allies to better coordinate enforcement of sanctions against North Korea.

The group said that while “the path to dialogue” with North Korea remained open, it was committed to “safeguard the global nonproliferation regime and address the threat arising from the Democratic People’s Republic of Korea’s [DPRK, North Korea’s official name] weapons of mass destruction and ballistic missile programs, which are in violation of U.N. Security Council resolutions.”

Some analysts suggest that by sending troops to support Russia’s war on Ukraine, North Korea may gain an opportunity to test the effectiveness of its ballistic missiles and munitions.

“We have communicated with the PRC about this matter to make clear that we are concerned about it, and that they ought to be concerned about this destabilizing action by two of its neighbors, Russia and North Korea,” Miller added. He was referring to People’s Republic of China.

Victor Cha, Korea chair at the Washington-based Center for Strategic and International Studies, noted that while China has been supportive of Russia’s war in Ukraine, North Korea’s involvement introduces an unsettling dynamic.

“For one,” Cha said, “China does not like Russia to have so much influence over North Korea.”

Cha added that Beijing could take specific actions, such as curbing exports of petroleum coke to North Korea, which can be used in munitions production.

“According to recent public reports, imports of this good [used for steel production] have dramatically increased while overall trade has only slowly started to return to normal,” he said.

Defense Department spokeswoman Sabrina Singh said Austin would also meet with his South Korean counterpart Wednesday, when he will host Kim at the Pentagon for the 56th U.S.-ROK Security Consultative Meeting. ROK refers to South Korea’s official name, the Republic of Korea.
