Russia has to buy military hardware from North Korea and Iran as sanctions squeeze its ability to supply weaponry. Iran and North Korea, also targets of sanctions, have deepened ties with Russia since Putin invaded Ukraine. Kim Jong-un accused the West of pursuing a ‘hegemonic policy’ that justified Russia's use of force, and vowed to deepen ‘comradely friendship’ with Moscow. Putin said the two countries would expand their ‘comprehensive and constructive bilateral relations’. Last week the Biden administration said the first shipments of Iranian-made drones had been delivered to Russia, and Russian operators are in Iran receiving training on the Mohajer-6 and Shahed series weapons. Many of the drones have been beset by mechanical and technical problems since delivery. Iran officially denied delivering weapons to either side of the conflict, but the USA said Tehran was planning to supply Moscow with potentially hundreds of drones, some with combat capabilities for its war in Ukraine.
