Russian President Vladimir Putin met North Korea's foreign minister in the Kremlin on Monday at a time of mounting concern in the West that North Korean soldiers are about to enter the Ukraine war on Moscow's side. Video of the meeting showed the pair shaking hands for a full minute as Putin greeted Choe Son Hui. Putin noted that they were meeting on Russia's National Unity Day, a public holiday, and Choe conveyed "sincere, warm, comradely greetings" from North Korean leader Kim Jong Un.
