The United States Department of Commerce is reportedly considering lawmakers' calls to make it harder for China to use the RISC-V instruction set architecture (ISA).

"While the benefits of open source collaboration on RISC-V promise to be significant, it can only be realized when contributors are working with the sole aim of improving the technology, and not aiding the geopolitical interests of the PRC," the representatives wrote in a November 2023 letter that called for creation of a "robust ecosystem for open source collaboration among the US and our allies while ensuring the PRC is unable to benefit from that work."

It's not clear what actions might or even could be taken. Their potential effectiveness is also debatable, as US tech bans haven't stopped China importing banned GPUs, while various actors have developed numerous evasion routes to bring banned tech into the Middle Kingdom.
