We don't know because the picture isn't very clear.
It *could* be a domestic variant of the CS/LR-17 but I would be surprised if that were the case given CS/LR-17 is a product first shown for export and given how carefully the PLA have guarded pictures of the new service rifle over the last couple of years.
That said the new rifle will almost definitely have lots of commonalities with the CS/LR-17 in terms of general configuration and various design features. But I would be surprised if it was a model or a variant of the CS/LR-17.
