This is the best summary I could come up with:

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).

In late 2023, members of the House Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party (CCP) expressed concern that the Uncle Sam's many efforts to make it hard for advanced chips to reach China are being undermined by RISC-V.

"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."

That's code for "Banning sales of chips to China won't work if Beijing can build its own using RISC-V." The Committee members therefore called on US commerce secretary Gina Raimondo to consider what might be done about RISC-V.

RISC-V International CEO Calista Redmond defended open source collaboration, on grounds that it advances the development technology and leads to the creation of very useful things like USB and Ethernet, and pointed out that her own org is a mere publisher of a standard.

China has made it plain that it wants more of this sort of thing, by approving only processors it can control to some extent – because their architectures allow customization – and issuing its own bans on the import of US tech.
