Are you supporting her bottom? Rabbits often struggle if they feel they might fall, so one hand firmly under their rear end should help. I also find that when China struggles (she does sometimes), I hold her as close to me as possible, as low to the ground as possible, support her rear end, and speak softly and reassuringly, tickling her chin. She always calms down then and realises that she's safe in my hands. The trick is to make them feel as safe and reassured as possible.
Do it in stages, your rabbit will respond to things done on her terms. Good luck!
