Just came across an overview of AI policy for 2022 published by AI Hub. It covers ongoing AI policy debates across different regions. It also suggests this great EuropeanAI Newsletter. Not at all a comprehensive source, but a good place to start mapping developments.
United States: Blueprint for AI Bill of Rights
Canada: Draft Law on AI
Europe: Artificial Intelligence Liability Directive (AILD), following the 2021 proposed legal framework, and the 2020 white paper.
