It replicates worldwide, it's not a US thing.

What do you mean "it replicates worldwide"? What replication are you referring to?

IQ differences between ethnic/population groups/racial groups. It's not only a US phenomenon

I don't think it's a US phenomenon in particular; I'm saying we have data about the US, and not about the rest of the world.

People tend to say this before citing "IQ and the Wealth of Nations" or something derived from it.

The US racial groups are US specific. The bundling of different ethnicities into a race (like grouping high pigmented out of Africa with Africans instead of with low pigmented out of Africa) is silly.
