It's worth pointing out that fabless design companies build upon reference designs (whether ARM or RISC V) created by other companies (eg, ARM Holdings or SiFive), and both these kinds of businesses and are distinct from semiconductor fabrication companies like Taiwan's TSMC. Although fabless design companies like Allwinner and fabrication companies like SMIC both exist in China, there is accessible pathways to China-free chips, especially if you're willing to pay the premium for TSMC's high end manufacturing.
