More than two and a half years into the war in Ukraine, Russian President Vladimir Putin has gone to an ally for help.  Several thousand North Korean troops have arrived in Russia and are expected to join the fight.  Today, Russia expert Matthew Sussex from the Centre for European Studies at the ANU on what it means for the war. He explains that the North Korean troops are likely to be used in rear-area roles initially, freeing up Russian soldiers for front-line combat.  He highlights that this move is a significant escalation, as it involves a country from Asia sending troops to Europe.  Professor Sussex also discusses the potential benefits for North Korea, including military modernisation and enhanced missile capabilities.  Featured:  Matthew Sussex, an associate professor at the Centre for European studies at the Australian National University Key Topics: Ukraine war Russia-North Korea alliance North Korean military Vladimir Putin Kim Jong-un Russia-China relations South Korea
