Others have already talked about the Japanese and Suadis.

My point would be that it has already been demonstrated that you can lose access to ARM technology as a consequence of US sanctions.

ARM is not a sufficiently independent ISA to guarantee sovereignty.

With RISC-V, you may lose access to a specific core, chip, or supply chain. But your ecosystem can pivot to an alternative. Long-term, you have the option of complete in-sourcing.

So, even working with Chinese chips and boards today can be progress, as long as more domestic RVA23 options can be expected to arrive later.
