It's definitely significantly more common from China. I think part of it is Indian names can often be made easier for English speakers to work with anyways + cultural trends in recent times have made having unfamiliar sounding names less of a big deal over time. One of our teams is in Bangaluru with ~100 folks and maybe 8 of them bother using anglicized names in calls/emails.

A significant amount of my coworkers from India use a shortened form of their name, though.
