Crouching Tiger came out in 2000, so it wasn't a scheduling conflict with that film.
A film called THE TOUCH did come out in 2002, but filming had completed on January 12th of that year, just two days before filming began for DIE ANOTHER DAY. So perhaps she could have made her cameo as originally planned for the Hong Kong sequence. Too bad that didn't happen.
As far as THE TOUCH goes, she did have a scheduling conflict that prevented her from taking a role in the Matrix sequels. Had that not been an issue, she would have shared a scene with Monica Bellucci.
