I am not near left or right, a 1 line axis is not enough to put all the political positions into account.
After reading the first link, socialism is kindof interesting at its core, but in china you have a person that controls eveything, China is a totalitarian state capitalist system. While Socialism would give people freedom, China is doing the opposite. I am not fully invested into this topic but you can't tell me that stealing Money from bank accounts, allowing companies to do stupid investments that will become waste just to rise some numbers. Generally forbiding the fact that you have issues (disabled) or are different (religion or sexuality) is really just showing how similar this is to Hitlers time.
In Germany we have the Bundestag and its neither leftist or rightist as you elect the group you like which can be left-ist or right-ist, a group of multiple groups will be build for the few years that have together 50%. So if there is onr far-right group or far-left one, they won't be able to actually do all the harm except people elect that group 50%.
Besides having every few years either same or slight different groups that regime, there is also the Grundgesetz which protect the Human rights at its core and is not changable except all 2 buildings and 1 person allow for this. With this, everthing should be possible while having freedom.
But for China I really don't know what is the right thing. Its no different than America with capitalism at many levels because both intoxicate the human rights and nature environment. Somethinf like a Bundestag for China doesn't seem like a great idea if it would be the main thing, because China wants to grow and the Bundestag is too slow for direct and instant changes. But without, you can see corruption at many corners in China.
