Mongoloid admixture is minimal overall in India. India and china differ much more. I know old stock Americans differ but the demographics have changed. So the two countries are more similar now.

Nagaland?

Costa Rica and Colombia still have broadly the same elements Panama has, just in different proportions. In any case, certain regions like Limon and Choco are as Black if not more so than Panama itself is.

Nagaland?

Entiendo, pero esa región tiene 2 millones de personas, eso no es nada en un país como India donde hay más de mil millones de personas.

El limon es como Azuero mas Colon y el choco una version mas SSA del Darien, el Darien es mas nativo y algo menos SSA

It's China/Russia

[Damião de Góis]

China and India look very different but they barely have a border. The new world have recent population composition so the answer is probably Russia/China if ethnic russians live in the far east, which i'm not sure.

Or his mother cucked his father? Nigga, mutations happen all the time, light eyes does not always equate to colonial ancestry. Anyway, it's very evident that those Dominicans are of sub-saharan Africa ancestry and could pass in Africa as there are "mulatto looking" Africans like Phyno.

It is not only his light eyes, even his facial features look mixed. Most light skin Igbos still look completely Negroid despite being lighter than other Africans while his face looks mixed to me.
