The Council of Europe has made a #treaty on #AI (Treaty number 225), open to other signatories, and has been joined by the US and other countries. I've taken a quick look, and while it's mostly fluff (AI shall be used for good and not evil type stuff) there are a couple of useful bits.

There's a risk framework that states have to set up, to consider the graduated risks of AI in different areas. A possibility for a moratorium of AI use in specific high-risk areas. An obligation that, where AI is used to make decisions, people affected can challenge them and be given an understanding of the systems involved. There's also an obligation to assure to people that they are notified they are communicating with an AI rather than a human.
