The Chinese models are almost certainly taught to comply with "Chinese values" in the RLHF step, not from filtering the training data. There may be a few things which are too radioactive to be allowed even in the training material - but that's more likely to be things like child abuse images for a visual model, things non-Chinese values also have an issue with.

I'm pretty sure no county taking a stab at making their own model for sovereignty purposes will let "proper licensing" stand in their way.
