We really wouldn’t describe Li Shang as a love interest, so if the new film has a more traditional one, that’s a significant difference.
The animated feature didn’t really have a love interest at all.
While Mulan certainly has feelings for Li Shang, and he returns them once he discovers the truth about her, nobody takes action specifically in an attempt to build a relationship.
Even if Mulan will be the lead character, and even if all the other characters are Chinese, this quote still makes it look like there will be one significant change to the live-action version of the film.
