United States National Security Advisor Jake Sullivan said on Friday during a press briefing that Washington continues to be concerned over North Korea and Russia's "technology and security" relations.
Answering a question about a report that stated that Pyongyang's new missiles are potentially relying on Russia's technology, Sullivan noted that the US intelligence is "taking a hard look at" these reports. He added that although he is "not validating the reports," this is a "matter of concern."
Talking about third-party deliveries of F-16 fighter jets to Ukraine, he said that the pilot training "will be followed by the transfer" of this equipment.
