This isn't the case. People assume this is the case because only one side is reported for various reasons.

Just to be clear though: the Communist Party of China is not a massive fan of far-right parties, there are certain ideological barriers there.

Russia employed the former left-wing German Chancellor as part of their strategy making an invasion of Ukraine economically viable for them (it is worth pointing out that when right-wing politicians pointed this out, it was received as a crazy conspiracy theory..."liberal voters" distinguish themselves as people who believe themselves particularly unlikely to believe in "misinformation" whilst simultaneously believing in things that make no sense, most people who have a knowledge of politics are required to believe things that aren't true...if they were in touch with reality, they wouldn't vote).
