According to Jinder on a recent episode of Talk Is Jericho, he wasn't originally meant to be an anti-American character for his WWE title push. The original promo where he won the #1 contendership was very different and meant to tie into his old gimmick in order to transition to a new Jinder.
Instead Vince wanted the promo and character changed at the last minute to be another anti-American gimmick. Jinder initially didn't like the changes but realized afterwards it did help draw a lot of heat for his character.
