It spends a lot of time talking about the Indian's ability to cut through red tape, compared to the Chinese use of "connections", but only brings up "English" twice, and not as the decisive factor. I think it really plays down the importance of English skills.
I'd expect Brazilians to also do quite well, as they tend to have pretty good English.
The bottom line is these people speak English and are perceived to be able to bridge the gap between the East and West.
