This is a quite cool breakdown of the differences.
One thing it misses is in English (ie, the country) usage there is both.
Tea, obviously, is more common but the phrase "a cup of char" is clearly derived from the Chinese and Indian origins. Interestingly it (at least was) primarily a working class phrasing, possibly originating with sea-faring types and dock workers.
Of course now the US is confusing matters by making "chai" be ubiquitous for Massala chai, but that's a different matter!
