Imperialism much?

Wut? Oh, you think that's imperialism? Stating the fact that Taiwan is part of China and that Hong Kong is also just a region (SAR if you even know what that is) of China? All this shows is you have no fucking clue what imperialism even is. You literally don't know what that word means. Not by ML standards clearly, but not even by general layman standards. And it shows you know absolutely nothing about the history of this situation, which is typical of the sinophobic liberal. Taiwan is ran by a fascist nationalist government that tried to wipe out the workers movements and that still claims to be the "rightful" rulers not only of all of China but also other sovereign nations like Mongolia. And you're saying that China allowing them to continue to operate while slowly working towards future reunification is "imperialism." That's just sick. Take a look at what the US via the IMF and World Bank does to impoverished global south nations (that are impoverished solely because the US impoverished them for the purpose of subjugation and unequal exchange) to begin to understand what imperialism looks like. Then come back and tell me China's lenient position on Taiwan is "imperialism."

The US being bad doesn't make China good.

Never said it did. BUT part of why China is good is because it is overtaking the US which is unambiguously bad. This is one of the many things China is doing (in this case passively, but it does a hell of a lot of active good too) that is beneficial to humanity.

There is no nation in this world worth simping for.

I don't know what you think "simping" for a country even means, given it's a slang term involving romantic attraction, but if by "simping" for a nation, you mean "expressing vocal approval and ideologically supporting it," then yes, there are nations absolutely worth "simping" for. Cuba immediately comes to mind as the obvious one. But China also deserves the vocal approval and support of leftists since it is in fact a socialist state and is in fact doing much good in the world, both for the masses of people living within it as well as for most of the rest of the world through BRI and the fact that it is undermining the actual imperialist's ability to beat the global south into submission. Russia deserves critical support for the latter bit as well, seeing as it is doing more than any other state to actively fight imperialism and the monopolarity of US hegemony.
