If the US and/or UK place sanctions on exporting microprocessor technologies to China then that's that. Intel/AMD and ARM are subject to US and UK laws and regulations respectively.
RISC-V by contrast is much, much harder for any given country to regulate because of its free and open nature. At most the US and UK can embargo individual developments made within their jurisdictions, but they can't regulate the entire architecture. RISC-V doesn't have a kill switch named Intel/AMD or ARM.
