If the political system of the West is superior to that of the East, where is the evidence? Just because North America and Europe have developed economies?You mean Uyghurs that China imprisons for 6 years for growing a beard? It doesn't so much support them as simply think that they shouldn't be put in concentration camps. And as regards sovereignty, who does China belong to, the CCP or the people of China? The very name of China is a lie, 'People's Republic of China'. It should belong to the people but it belongs to the CCP right now. The mistake you and many others make is treating democracies and dictatorships as equal, they are not. Dictatorships are criminal enterprises, and this war has helped expose the amount of corruption behind the Russian state, generals with yachts instead of equipment.
The CCP is the only obstacle to One China, just as the Socialist Unity* Party of Germany was the only obstacle to German reunification from 1949-1989.
*Note yet another lie in a name, Communist dictatorships are good at that. Democratic People's Republic of Korea is especially good, because it has two lies in one name.
These have their origins in the dividends of the colonial era and the economic plundering of developing countries in the era of globalization. not because of so-called democracies
In other words, is the code of conduct in modern state relations the same as the political system of Western countries? Western countries dominate the international community. Anything that goes against Western values is evil?
