Are you sure, especially considering China?
I doubt there is any legal barrier, because there are a few existing projects with x86 cores on an FPGA, as well as some SoCs. Here's a 486: https://opencores.org/projects/ao486
Ok if China is doing something only for China market that tells you something.
As for opencores, yes you can design them, but do any companies making commercial products sell them?
I'm reasonably certain at least one Chinese fab has a license for some of AMDs older product lines
