If the US tried their own belt and road people would be screaming about "imperialism/colonialism/white privilege"... thing's aren't as cut and dried as US evil and "oh shucks that clever Chinese government, not great but not terrible"

I think you would find very few people who think belt and road wouldn't be vastly superior to what the us is doing now

I don't remember any violent backlash to the Marshal plan.

American "belt & road" has been tried, but in a neoliberal way, through WB and IMF, and it has been an utter failure (see Joe Stiglitz or Ha-Joon Chang for examples). Chinese are way more pragmatic (smarter) about it.
