Yes, I think they will, the change can probably be accelerated by pressure brought to bear by the West, Chinese culture is very ancient and has been largely remote to the rest of the World until this century. Pain, torture, cruelty, violence and barbarism are an integral part of that history and culture so it's a change of mind set that needs to brought home.
Consumers hold the key to bringing about this change, refusing to buy Chinese products whilst these atrocities persist, then change will be facilitated, when the fundamental justification for embracing and ignoring these horrors is denied-money! Retailers, importers, shippers will all bring pressure on the Chinese to behave in a civilised manner towards all living things. As long as money is more important than people (as it increasingly is in the West) the message will not get home.
For nearly ten years now I have not bought anything Chinese, always enquiring with the seller country of origin and labouring the point, if it's Chinese decline to purchase, explain why, and ask if they can offer a non Chinese product; to demonstrate I am not just a time waster.
This is the unstoppable consumer power that will change China!
