The China Russia Relationship

How relevant is this invasion of Ukraine along similar arguments that are presented by Russia about their aims and the legitimacy of their attack on Ukraine? I think it's a very uncomfortable moment when you know, China who keeps on saying all this stuff about territorial indivisibility and sovereignty. A lot of what China has been trying to do with its military modernization, for example, is kind of seeing the Russian system as a potential model to follow in some respects.
