Putin, during a rare visit to Pyongyang, signed a mutual defense pact on Wednesday with North Korean leader Kim Jong Un, who pledged his country’s “full support” for Russia’s invasion of Ukraine.
Speaking on Thursday in Vietnam, Putin said Moscow would not rule out sending weapons to Pyongyang, calling it repercussions for the West supplying Ukraine.
The threat “is incredibly concerning,” State Department spokesman Matthew Miller told reporters.
“It would destabilize the Korean peninsula, potentially, depending on the type of weapons, and might violate UN Security Council resolutions that Russia itself has supported,” Miller said.
