I would strongly caution you against falling for the identity politics of the West. It's not about "white" vs "colored" (I hate that term btw, as it implies being caucasian is normal while other ethnicities are aberrations). That's a narrative those in power use to divide the people.
When you focus on identity politics, you lose sight of who the real adversary is.
Western media attack Chinese achievements not because they're racist, but because the rise of China threatens the hegemonic power of the West. Racism is meaningless. It is a decoy created to misdirect the anger and frustrations of the people. Black slaves were not slaves because they had black skin, they were slaves because their nations were weak and could not defend themselves against the Europeans.
Your real enemies are the military industrial complex that is constantly in search of a new war, and the economic system that is always in search of new lands to exploit. AKA Imperialism and Capitalism.
Funny how little things have changed since 1949.
I think you may not have attended any course of "Social Economics based on Karl Max", or did you read something similar by yourself? Anyway, what you are saying is exactly the very basic of Karl Max's "Das Kapital", every human act is centered around one thing and one thing only, the economic activity, that determines everything human build on top of it, to justify, to defend and regulate. Capital is that economic activity, culture/religion/institution and racism included are just tools to serve the capital. There is no other struggles than class struggle.
To be clear, this is my compliment to you.
Truth can be discovered by a honest mind with logic, no need for text book or indoctrination.
