No county on Earth is perfect. China has genuine problems, like the urban/rural divide, hukou systen, and more. At the same time, it's a constantly progressing country, among the fastest in the world, with a system that ensures the working classes are the primary beneficiaries of this progress.

The US empire is a genocidal settler-colony. It engages in constant war and genocide, plunders the global south of their social surplus, preventing it from being reinvested in development, brutally oppresses ethnic minorities and indigenous populations, and can't even afford to bribe the white settlers any longer. The spoils all go to the wealthiest imperialists as the country continues to decay and die away.

China, meanwhile, is a progressive force for the global south. It is helping the global south develop, entitling them more to their social surplus and assisting with south-south trade. It's uplifting themselves, while undermining imperialism, which uplifts others. China is equipped to deal with its problems and is working on them, the US Empire is exporting its problems to the global south and reaping the rewards.

Equating China and the US is imperialism denial and genocide trivialization.
