I'm curious.
Is that a major thing in the Pacific Islands?
I know the Japanese and Chinese both hate Koreans.
It's not quite that simple. Koreans do (if perhaps subconsciously) view themselves as the master race in the region and a solid majority of Japanese are Korean descendants, but it's much wider than just that.
But in Asia the Bangladeshis have had issues with Africans, in Bhutan it's the Nepalese, in Myanmar it's been Muslims as well as "natives" and Chinese descendants, in Cambodia it's ethnic Chinese, Vietnamese and Thais. When I was in Bahrain they didn't care for anyone from India, Sri Lanka, Philippines, etc., which ironically is where most of their labor force came from. In the Philippines there's certainly a noticeable objection to Koreans and black people. Thai people have no love lost for Chinese, there are the Uyghurs in China, etc., etc., etc.
Jews, Muslims and Blacks don't fare well across much of Europe. I have friends from Australia and they've said it's surfaced quite a bit more over the past few decades whereas before Australia might have been viewed as one of the places it was least common.
imho most of the time it boils down to experience (or lack thereof), how one was raised, and education. Sadly there are many people that have the experience of being around "others" and they go to school, but they have shitbags for parents that brainwash them from an early age. Yet make no mistake - the belief for instance that someone of darker complexion is inferior to you is not uniquely innate to Americans. Not by a long shot.
I think you sell the French and British way short...
Agreed. And really putting Americans at #1 doesn't line up with my experience, albeit the US has a long way to go.
