There was nothing about Khan that tied him to India on the screen in the old continuity.

…you mean aside from the fact that he was a Sikh named “Khan Noonien Singh?”

There is a line of dialogue saying he came from India and a portrait of him is painted wearing a turban. The character was based on a war acquaintance of Roddenberry who was a religious Sikh as well of that ethnicity.

This thread is about racial stereotypes and Star Wars. The film in question was directed by the director of the current movie in the series.
